The native Mac C/C++ compilers (Clang) do not support OpenMP so CMake by
default disables OpenMP for the project since it requires all project compilers
to support it. This means that we have to hack the build script on Mac to
compile the Fortran sources with OpenMP turned on and manually link in the
required OpenMP run time support to the executables.
This hack presumes that the Fortran compiler on Mac is gfortran.

Also moved the same large array from stack to heap which along with
other prior changes now allows the Windows jt9 OpenMP executable to
run with a default stack size again.
This also removes a crash on the Mac version which was probably due to
excessive stack usage.
Net result is an even faster JT9 decoder.

Set the CMake variables CMAKE_OSX_SYSROOT and CMAKE_OSX_DEPLOYMENT_TARGET
must be set before the project() command since they can effect compiler
detection and capability tests.
Only use the -stdlib=libc++ option on Mac OS X when using Clang tools.
On other platforms with Clang tools libc+ is not currently the best choice.

This change introduces the program jt9_omp which is a testbed for a
multi-threaded version of the jt9 decoder program. The program jt9_omp
should be a directly substitutable for jt9 except that JT65 and JT9
decodes are computed in parallel.
Also enable the OpenMP directives in decoder.f90 - note this is not
yet a working multi-threaded decoder and the existing jt9 is still the
correct decoder to be used in WSJT-X.
Increased the available stack size for jt9_omp.exe as this is a hard
limit on Windows and the default is not big enough for the OpenMP
version of jt9.
Also Fortran array bounds checking is now disabled for Release
configuration builds so as to improve performance a little.

The long FFTs can now use the multi-threaded FFTW routines.
Subroutine decode9.f90 was renamed jt9fano.f90.
The JT9 decoder's top-level functions were removed from decoder.f90
and put into a separate subroutine decjt90.f90.
Subroutine decoder.f90 is now configured for possible use of OpenMP
SECTIONS, with the JT9 and JT65 decoders running concurrently on
a multi-core machine. Note, however, that this concurrent processing
is not yet fully implemented. Probably calls to timer need to be removed;
some variables used in calls to jt65a and decjt9 may need to be
declared PRIVATE in decoder; some sections probably need to be declared
CRITICAL; probably some SAVE statements in downstream routines have
made them not thread-safe; etc., etc.
I'm a neophyte at using OpenMP. Comments, suggestions, and/or tests by
others will be welcome!

New command-line option for jt9: [-m nthreads]. Default is nthreads=1.
Also refactored a loop in filbig.f90 that was taking far too much
time.

The kvasd binary need only be downloaded if the MD5 hash for it has
changed.
Also fixed a defect in the status check of the MD5 hash download.
Also switched to HTTP protocol as it is quick and gives clearer error
messages.

The rigctl program is not used directly by WSJT-X but it does contain
the same Hamlib code from the Hamlib v3 fork as WSJT-X and
rigctld-wsjtx. So it makes sense to distribute it as a testing tool or
for any user that needs it to converse with the rigctld-wsjtx server.
Merged from wsjtx-1.4 branch.

Pass the temporary directory to jt9 and use it to give the correct
paths to temporary files. Also jt9 passes the absolute path to
kvasd.dat in the temporary directory to kvasd.
Clear out all the annoying cruft that has accumulated due to having to
run with $CWD as the temporary directory.
Use QStandardPaths to find the writable data directory where needed
rather than passing it around between objects. This now works because
the $CWD hasn't been changed.
Do away with the CMake option WSJT_STANDARD_FILE_LOCATIONS as it is no
longer needed.
Fix astro status file azel.dat formatting.

To comply with the WSJT_X GPL v3 license, the closed source KVASD
executable must be delivered separately and optionally to end
users. To facilitate this a new install option has been added to the
Windows installer to install KVASD by downloading it at install
time. The installer first downloads the KVASD EULA from the Internet
and presents it to the user for reading and agreement. If agreement
is given the KVASD binary is downloaded from the Internet and
checksummed using an MD5 hash, if that passes, it is installed along
with WSJT-X. An uninstall record is also written to ensure that, if
installed, KVASD will be un-installed if WSJT-X is un-installed.
To facilitate this enhancment to the NSIS installer the standard CPack
NSIS installer script template has been overridden with a project
specific version. This version also implements the more modern and
recomended nsDialogs mechanism for installer custom page construction
including the install options page. See CMake/Modules/NSIS.template.in
for details and CMakeCPackOptions.cmake.in for usage in this
installer.

In order to support the WSJT-X super build in LOCAL mode the location
of the User Guide needs to be specified.
A CMake cache variable WSJT_MANUAL_DIRECTORY has been added to allow

The minimum OS X version supported and SDK selection compiler options
were not being set for Fortran compiles on Mac.
As CMake 3.0.2 is the current release the facilities obsoleted by
CMake 3.0 have been removed. This also entails making CMake 2.8.10 the

The normal way to view console output from a Windows GUI application
(i.e. with a WinMain entry point) is to attach a debugger which will
then receive the application console output in its own console.
If it is required to build wsjtx.exe as a console application it may
be done by setting the new WSJT_CREATE_WINMAIN CMake option to
OFF. This option is only available for Debug configuration builds to
avoid accidental shipping of non-Debug configuration builds as a
console application.

Routine packmsg now tries the shortlist (Type 1 prefix or suffix) first.

of all valid types.

An ambiguity existed between release candidates and development
versions as there was no definitive identification for development
versions.
Added a new version number suffix of '-devel' which appears if the
release candidate number is missing or zero in Versions.cmake and the

Also re-factored setting of version number suffiexes to a single place
in in CMake/VersionCompute.cmake.

The location of documentation files on Linux distributions is
controlled to a certain extent. Using the QStandardPaths::locate()
method helps us with this.
Work round the misbehaviour of QCoreApplication::applicationDirPath()
when the CWD has been changed by working out the documentation
location before changing the CWD to a temporary directory. This path
is now provided by the Configuration settings class which also manages
other run time paths.
Updated Debian packaging to move a little nearer a conforming DEB
file.
Added a basic manpage for rigctld-wsjtx.

So that a manual can be viewed without an Internet connection a second
manual action has been added to the WSJT_X help menu. This shells out
to the default web browser with a local file target.
The build has been enhanced to install and package the current version
of the HTML user manual as downloaded from the project web site at
build time
The package file locations have been adjusted to be compatible with
the QStandardPaths class so that its locate() method can be used to
portably access resources like this local help file

Use the data-sections and function-sections gcc/g++ compiler options
to create sections for each function and data item then use
gc-sections in the link to discard all unreferenced sections.
This has most benefit if the hamlib library we statically link is also
compiled with data-sections and function-sections.
