GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Note: Because PortAudioCpp is now in the main PortAudio SVN repository, having these per-release changelogs probably doesn't make much sense anymore. Perhaps it's better to just note mayor changes by date from now on.
PortAudioCpp v19 revision 16 06/05/22:
mblaauw:
- Added up-to-date MSVC 6.0 projects created by David Moore. Besides MSVC 6.0 users, MSVC 7.0 users may use these projects and automatically convert them to MSVC 7.0 projects.
- Changed the code and projects (MSVC 7.1 only) to be up-to-date with PortAudio's new directory structure.
- Added equivalents of the PaAsio_GetInputChannelName() and PaAsio_GetOutputChannelName() functions to the AsioDeviceAdapter wrapper-class (missing functions pointed out by David Moore).
- Added code to PortAudio's main SVN repository.
PortAudioCpp v19 revision 15 (unknown release date):
mblaauw:
- Changed some exception handling code in HostApi's constructor.
- Added accessors to PortAudio PaStream from PortAudioCpp Stream (their absense being pointed out
by Tom Jordan).
- Fixed a bug/typo in MemFunToCallbackInterfaceAdapter::init() thanks to Fredrik Viklund.
- Fixed issue with concrete Stream classes possibly throwing an exception and fixed documentation w.r.t. this.
- Moved files to portaudio/binding/cpp/. Made new msvc 7.1 projects to reflect the change and removed msvc 6.0
and 7.0 projects (because I can no longer maintain them myself). Gnu projects will probably need updating.
PortAudioCpp v19 revision 14 03/10/24:
mblaauw:
- Fixed some error handling bugs in Stream and System (pointed out by Tom Jordan).
- Updated documentation a little (main page).
- Fixed order of members so initializer list was in the right order in
StreamParameters (pointed out by Ludwig Schwardt).
- Added new lines at EOF's (as indicated by Ludwig Schwardt).
PortAudioCpp v19 revision 13 03/10/19:
lschwardt:
- Added build files for GNU/Linux.
- Fixed bug in Exception where the inherited what() member function (and destructor) had looser
exception specification (namely no exception specification, i.e. could throw anything) than
the std::exception base class's what() member function (which had throw(), i.e. no-throw guarantee).
- Changed the iterators so that they have a set of public typedefs instead of deriving the C++ standard
library std::iterator<> struct. G++ 2.95 doesn't support std::exception<> and composition-by-aggregation
is prefered over composition-by-inheritance in this case.
- Changed some minor things to avoid G++ warning messages.
mblaauw:
- Renamed this file (/WHATSNEW.txt) to /CHANGELOG.
- Renamed /PA_ISSUES.txt to /PA_ISSUES.
- Added /INSTALL file with some build info for GNU/Linux and VC6.
- Added MSVC 6.0 projects for building PortAudioCpp as a staticly or dynamically linkable library.
- Moved build files to /build/(gnu/ or vc6/).
- Moved Doxygen configuration files to /doc/ and output to /doc/api_reference/.
- Added a /doc/README with some info how to generate Doxygen documentation.
PortAudioCpp v19 revision 12 03/09/02:
mblaauw:
- Updated code to reflect changes on V19-devel CVS branch.
- Fixed some typos in the documentation.
PortAudioCpp v19 revision 11 03/07/31:
mblaauw:
- Renamed SingleDirecionStreamParameters to DirectionSpecificStreamParameters.
- Implemented BlockingStream.
- Updated code to reflect recent changes to PortAudio V19-devel.
- Fixed a potential memory leak when an exception was thrown in the HostApi
constructor.
- Renamed ``Latency'' to ``BufferSize'' in AsioDeviceAdapter.
- Updated class documentation.
PortAudioCpp v19 revision 10 03/07/18:
mblaauw:
- SingleDirectionStreamParameters now has a (static) null() method.
- StreamParameters uses references for the direction-specific stream parameters
instead of pointers (use null() method (above) instead of NULL).
- StreamParameters and SingleDirectionStreamParameters must now be fully specified
and now default values are used (because this was not very useful in general and
only made things more complex).
- Updated documentation.
PortAudioCpp v19 revision 09 03/06/25:
mblaauw:
- Changed some things in SingleDirectionStreamParameters to ease it's usage.
- Placed all SingleDirectionStreamParameters stuff into a separate file.
+ Totally redid the callback stuff, now it's less ackward and supports C++ functions.
PortAudioCpp v19 revision 08 03/06/20:
mblaauw:
- Made deconstructors for Device and HostApi private.
+ Added a AsioDeviceWrapper host api specific device extension class.
- Refactored Exception into a Exception base class and PaException and PaCppException
derived classes.
- Added ASIO specific device info to the devs.cxx example.
- Fixed a bug in System::hostApiCount() and System::defaultHostApi().
+ Moved Device::null to System::nullDevice.
- Fixed some bugs in Device and System.
PortAudioCpp v19 revision 07 03/06/08:
mblaauw:
- Updated some doxy comments.
+ Renamed CbXyz to CallbackXyz.
+ Renamed all ``configurations'' to ``parameters''.
+ Renamed HalfDuplexStreamConfiguration to SingleDirectionStreamConfiguration.
- Renamed SingleDirectionStreamParameters::streamParameters() to
SingleDirectionStreamParameters::paSteamParameters.
- Added a non-constant version of SingleDirectionStreamParameters::paStreamParameters().
- A few improvements to SingleDirectionStreamParameters.
- Allowed AutoSystem to be created without initializing the System singleton
(using a ctor flag).
- Added a BlockingStream class (not implemented for now).
- Fixed many bugs in the implementation of the iterators.
- Fixed a bug in Device::operator==().
+ Added a C++ version of the patest_sine.c test/example.
- Added a ctor for StreamParameters for a default half-duplex stream.
- Added SingleDirectionStreamParameters::setDevice() and setNumChannels().
- Renamed System::numHostApis() to System::hostApiCount().
+ Rewrote the iterators and related classes. They are now fully STL compliant. The System now
has a static array of all HostApis and all Devices. Only the System can create HostApis and
Devices and they are non-copyable now. All HostApis and Devices are now passed by-reference.
- Renamed (System::) getVersion() to version() and getVersionText() to versionText().
- Renamed (Device::) numXyzChannels() to maxXyzChannels().
- Changed some stuff in StreamParameters.
+ Added a C++ version of the patest_devs.c test/example.
PortAudioCpp v19 revision 06 03/06/04:
mblaauw:
+ Added this file to the project (roughly, a `+' denotes a major change, a `-' a minor change).
- Added System::deviceByIndex(), useful when a Device's index is stored for instance.
- Renamed System::hostApiFromTypeId() to System::hostApiByTypeId().
- Updated and added some Doxygen documentation.
- Made Stream::usedIntputLatency(), Stream::usedOutputLatency() and
Stream::usedSampleRate() throw an paInternalError equivalent exception instead of paBadStreamPtr.
- Changed exception handling in Stream::open() functions. They now follow the PA error handling
mechanism better and a couple of bugs regarding ownership of objects were fixed.
- Renamed Device::isDefaultXyzDevice() to Device::isSystemDefaultXyzDevice().
- Added Device::isHostApiDefaultXyzDevice().
- Added StreamConfiguration::unsetFlag().
- Removed CUSTOM from SampleDataFormat.
- System::hostApiByTypeId() now throws an paInternalError if the type id was out-of-range; this
is a temporary work-around (see comments).
- Changed CbInterface to use paCallbackFun() instead of operator()().
- Renamed ``object'' to ``instance'' in CbMemFunAdapter.hxx.
- Added StreamConfiguration::setXyzHostApiSpecificSampleFormat().
- Added StreamConfiguration::isXyzSampleFormatHostApiSpecific().
- Changed error handling in System::terminate(), it can now throw an Exception.
- Added error handling in System::defaultHostApi().
- Added error handling in System::hostApisEnd().
- Changed some (but probably not all) C casts to C++ casts to avoid confusion with a
certain Python person.
- Renamed RaiiSystem to AutoSystem (class and file) as this is a come common convention.
- Renamed System::numDevices() to System::deviceCount() to be more compatible with PortAudio
(although PortAudio uses Pa_CountDevices() instead, see comment).
- Renamed HostApi::numDevices() to HostApi::deviceCount().
- Changed INC_ to INCLUDED_ in the header multiple include guards.
- Changed the order of functions in the StreamConfiguration class' header.
- Written some more info in PortAudioCpp.hxx (Doxygen).
- Added CallbackStream.hxx and CallbackStream.cxx files.
+ Refactored StreamConfiguration to remove the duplication which was there. There is now a
HalfDuplexStreamConfiguration class. Also made some improvements to these classes while
doing the refactoring.
+ Moved all code files to source/portaudiocpp/ and changed includes.
+ Moved all header files to include/portaudiocpp/ to easy a binary build if needed. The project
must be set to have .../include/ as a path to look for includes.
+ Refactored the Stream class into a Stream base class and a CallbackStream derived class.
- Renamed Stream::usingXyz() to Stream::xyz().
- Updated some doxy comments.
- Changed ``using namespace portaudio'' in .cxx files to ``namespace portaudio { ... }''.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script). Here is a another example:
/bin/bash ./configure CONFIG_SHELL=/bin/bash
Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
configuration-related scripts to be executed by `/bin/bash'.
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

/// <h1>PortAudioCpp - A Native C++ Binding of PortAudio V19</h1>
/// <h2>PortAudio</h2>
/// <p>
/// PortAudio is a portable and mature C API for accessing audio hardware. It offers both callback-based and blocking
/// style input and output, deals with sample data format conversions, dithering and much more. There are a large number
/// of implementations available for various platforms including Windows MME, Windows DirectX, Windows and MacOS (Classic)
/// ASIO, MacOS Classic SoundManager, MacOS X CoreAudio, OSS (Linux), Linux ALSA, JACK (MacOS X and Linux) and SGI Irix
/// AL. Note that, currently not all of these implementations are equally complete or up-to-date (as PortAudio V19 is
/// still in development). Because PortAudio has a C API, it can easily be called from a variety of other programming
/// languages.
/// </p>
/// <h2>PortAudioCpp</h2>
/// <p>
/// Although, it is possible to use PortAudio's C API from within a C++ program, this is usually a little awkward
/// as procedural and object-oriented paradigms need to be mixed. PortAudioCpp aims to resolve this by encapsulating
/// PortAudio's C API to form an equivalent object-oriented C++ API. It provides a more natural integration of PortAudio
/// into C++ programs as well as a more structured interface. PortAudio's concepts were preserved as much as possible and
/// no additional features were added except for some `convenience methods'.
/// </p>
/// <p>
/// PortAudioCpp's main features are:
/// <ul>
/// <li>Structured object model.</li>
/// <li>C++ exception handling instead of C-style error return codes.</li>
/// <li>Handling of callbacks using free functions (C and C++), static functions, member functions or instances of classes
/// derived from a given interface.</li>
/// <li>STL compliant iterators to host APIs and devices.</li>
/// <li>Some additional convenience functions to more easily set up and use PortAudio.</li>
/// </ul>
/// </p>
/// <p>
/// PortAudioCpp requires a recent version of the PortAudio V19 source code. This can be obtained from CVS or as a snapshot
/// from the website. The examples also require the ASIO 2 SDK which can be obtained from the Steinberg website. Alternatively, the
/// examples can easily be modified to compile without needing ASIO.
/// </p>
/// <p>
/// Supported platforms:
/// <ul>
/// <li>Microsoft Visual C++ 6.0, 7.0 (.NET 2002) and 7.1 (.NET 2003).</li>
/// <li>GNU G++ 2.95 and G++ 3.3.</li>
/// </ul>
/// Other platforms should be easily supported as PortAudioCpp is platform-independent and (reasonably) C++ standard compliant.
/// </p>
/// <p>
/// This documentation mainly provides information specific to PortAudioCpp. For a more complete explaination of all of the
/// concepts used, please consult the PortAudio documentation.
/// </p>
/// <p>
/// PortAudioCpp was developed by Merlijn Blaauw with many great suggestions and help from Ross Bencina. Ludwig Schwardt provided
/// GNU/Linux build files and checked G++ compatibility. PortAudioCpp may be used under the same licensing, conditions and
/// warranty as PortAudio. See <a href="http://www.portaudio.com/license.html">the PortAudio license</a> for more details.

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
