Installing WSJT-X
=================
Binary packages of WSJT-X are available from the project web site:
http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html
Building from Source
====================
On Linux systems some of the prerequisite libraries are available in
the mainstream distribution repositories. They are Qt v5 and FFTW v3.
For MS Windows see the section "Building from Source on MS Windows"
below. For Apple Mac see the section "Building from Source on Apple
Mac".
Qt v5, preferably v5.1 or later is required to build WSJT-X.
Qt v5 multimedia support and serial port is necessary as well as the
core Qt v5 components, normally installing the Qt multimedia
development package and Qt serialport development package are
sufficient to pull in all the required Qt components and dependants as
a single transaction. On some systems the Qt multimedia plugin
component is separate in the distribution repository an it may also
need installing.
The single precision FFTW v3 library libfftw3f is required along with
the libfftw library development package. Normally installing the
library development package pulls in all the FFTW v3 libraries
including the single precision variant.
The Hamlib library is required. Currently WSJT-X needs to be built
using a forked version of the Hamlib git master. This fork contains
patches not yet accepted by the Hamlib development team which are
essential for correct operation of WSJT-X. To build the Hamlib fork
from sources something like the following recipe should suffice:
mkdir ~/hamlib-prefix
cd ~/hamlib-prefix
git clone git://git.code.sf.net/u/bsomervi/hamlib src
cd src
git checkout integration
mkdir ../build
cd ../build
../src/autogen.sh --prefix=$HOME/hamlib-prefix \
--disable-shared --enable-static \
--without-cxx-binding --disable-winradio \
CFLAGS="-fdata-sections -ffunction-sections" \
LDFLAGS="-Wl,--gc-sections"
make
make install
This will build a binary hamlib package located at ~/hamlib-prefix so
you will need to add that to your CMAKE_PREFIX_PATH variable in your
WSJT-X build. On Linux that is probably the only path you have on
CMAKE_PREFIX_PATH unless you are using a locally installed Qt
installation.
To get the sources either download and extract a source tarball from
the project web site or preferably fetch the sources directly from the
project's subversion repository. The project svn repository has a
non-standard layout in that the WSJT-X project is not on the trunk,
instead the main code line is in a branch at ^/branches/wsjtx
mkdir -p ~/wsjtx-prefix/build
cd ~/wsjtx-prefix
svn checkout svn://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx src
To build WSJT-X you will need CMake and asciidoc installed.
cd ~/wsjtx-prefix/build
cmake -D CMAKE_PREFIX_PATH=~/hamlib-prefix ../src
cmake --build .
cmake --build . --target install
The recipe above will install into /usr by default, if you wish to
install in you own directory you can add a prefix-path to the
configure step like:
cd ~/wsjtx-prefix/build
cmake -D CMAKE_PREFIX_PATH=~/hamlib-prefix \
-D CMAKE_INSTALL_PREFIX=~/wsjtx-prefix ../src
cmake --build .
cmake --build . --target install
this will install WSJT-X at ~/wsjtx-prefix.
Building from Source on MS Windows
==================================
Because building on MS Windows is quite complicated there is an
Software Development Kit available that provides all the prerequisite
libraries and tools for building WSJT-X. This SDK is called JT-SDK-QT
which is documented here:
http://physics.princeton.edu/pulsar/K1JT/wsjtx-doc/dev-guide-main.html
If you need to build Hamlib rather than use the Hamlib kit included in
the JT-SDK the following recipe should help. Reasons for building
Hamlib from source might include picking up the very latest patches or
building a different branch that you wish to contribute to.
On Windows there is a complication in that the compilers used to build
Qt and WSJT-X are the MinGW ones bundled with the Qt package but
Hamlib needs to be build from an MSYS shell with the tools required to
build an autotools project. This means that you need to tell the
Hamlib configuration to use the Qt bundled MinGW compilers (if you
don't then the thread support library use by Hamlib will be
incompatible with that used by Qt and WSJT-X). So on Windows the
Hamlib build recipe is something like:
In an MSYS shell:-
mkdir ~/hamib-prefix
cd ~/hamlib-prefix
git clone git://git.code.sf.net/u/bsomervi/hamlib src
cd src
git checkout integration
mkdir ../build
cd ../build
../src/autogen.sh --prefix=$HOME/hamlib-prefix \
--disable-shared --enable-static \
--without-cxx-binding --disable-winradio \
CC=<path-to-Qt-MinGW-tools>/gcc \
CXX=<path-to-Qt-MinGW-tools>/g++ \
CFLAGS="-fdata-sections -ffunction-sections" \
LDFLAGS="-Wl,--gc-sections"
make
make install
NOTE: <path-to-Qt-MinGQ-tools> should be substituted with the actual
path to your Qt bundled tools e.g on my system it is
C:\Tools\Qt\Tools\mingw48_32\bin
This will leave a Hamlib binary package installed at
c:/Users/<user-name>/hamlib-prefix which is what needs to be on your
CMAKE_PREFIX_PATH. On Windows you almost certainly will be using a
CMake tool chain file and this is where you will need to specify the
Hamlib binary location as one of the paths in CMAKE_PREFIX_PATH.
Building from Source on Apple Mac
=================================
These instructions are adapted from my Evernote page at:
https://www.evernote.com/pub/bsomervi/wsjt-xmacbuilds
There are several ways to get the required GNU and other open source
tools and libraries installed, my preference is MacPorts because it is
easy to use and does everything we need.
You will need Xcode, MacPorts, CMake and, Qt. The Xcode install
instructions are included in the MacPorts documentation.
MacPorts
--------
Install MacPorts from instructions here:
http://www.macports.org/install.php
More detailed instructions are available in the documentation:
https://guide.macports.org
The ports that need to be installed are:
autoconf
automake
libtool
pkgconfig
texinfo
gcc49
fftw-3-single +gcc49
asciidoc
These are install by typing:
sudo port install autoconf automake \
libtool pkgconfig texinfo gcc49 asciidoc \
fftw-3-single +gcc49
Once complete you should have all the tools required to build WSJT-X.
Uninstalling MacPorts
---------------------
If at some point you wish to remove the ports from your machine. The
instructions are here:
https://guide.macports.org/#installing.macports.uninstalling .
Hamlib
------
First fetch hamlib from the repository, in this case my fork of Hamlib
3 until the official repository has all the fixes we need:
mkdir -p ~/hamlib-prefix/build
cd ~/hamlib-prefix
git clone git://git.code.sf.net/u/bsomervi/hamlib src
cd src
git checkout integration
The integration branch is my system testing branch which has all my
latest published changes.
You need to make one small change to the sources to build on OS X
using the MacPorts tools, here is a sed command to make the change:
sed -i.orig '/libtoolize/s/lib/glib/' autogen.sh
To build:
cd ~/hamlib-prefix/build
../src/hamlib/autogen.sh \
--enable-static \
--disable-shared \
--disable-winradio \
--prefix=$HOME/hamlib-prefix
make
make install-strip
The above commands will build hamlib and install it into ~/hamlib-prefix
Qt
--
The binary Qt distributions from http://www.qt.io/download
unfortunately are built to use the libstdc++ C++ support library,
WSJT-X uses a less geriatric C++ dialet which uses the libc++ C++
support library. This means that you need to build Qt from
sources. This is not difficult but does take some time.
Download the Qt source tar ball from
http://www.qt.io/download-open-source/, the link is about half way
down the page, you want the full sources tar ball shown as a 'tar.gz'
link.
Unpack the sources and cd into the top level directory then type:
$ ./configure -prefix ~/local/qt-macx-clang -opensource \
-confirm-license -platform macx-clang -silent -nomake tests \
-nomake examples -sdk macosx10.10 -skip qtwebkit \
-skip qtwebkit-examples -skip qtquick1 -skip qtconnectivity \
-skip qtlocation -skip qtsensors -skip qtscript \
-skip qtwebsockets -skip qtwebengine -skip qtwebchannel \
-skip qtwayland -skip qtquickcontrols -skip qtdeclarative \
-skip qtxmlpatterns -skip qtenginio
$ make -j4
$ make install
If you are building on 10.8 or don't have the 10.10 Mac SDK (Xcode 6)
available, you can substitute '-sdk macosx10.9' above.
The build above will take a few hours to complete.
CMake
-----
Although CMake is available via MacPorts I prefer to use the binary
installer from cake.org as the MacPorts port doesn't include the
graphical CMake tool cmake-gui which I find quite useful.
Fetch the latest CMake universal 64-bit DMG from
http://www.cmake.org/download/ open the DMG then drag and drop the
application bundle onto the supplied /Applications link.
To complete the install process you need to run the CMake application
as root from a terminal shell:
sudo /Applications/CMake.app/Contents/MacOS/CMake
in the CMake application choose "Tools->Install For Command Line Use"
from the menu and then click the "Install Command Line Links".
WSJT-X
------
First fetch the source from the repository:
mkdir -p ~/wsjtx-prefix/build
cd ~/wsjtx-prefix
svn checkout svn://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx src
this links to the Subversion repository in a read-only fashion, if you
intend to contribute to the project then you probably want to get a
developer login and use a read-write checkout. Even if you don't it
can be upgraded at a later date.
The checkout is of the latest code on the project trunk, i.e. the
development branch. You can easily switch the checkout to another
branch or even a tag if you want to build a prior published
generation. For now we will build the latest development sources. To
configure:
cd ~/wsjtx-prefix/build
FC=gfortran-mp-4.9 \
cmake \
-D CMAKE_PREFIX_PATH="~/local/qt-macx-clang;~/hamlib-prefix;/opt/local" \
-D CMAKE_INSTALL_PREFIX=~/wsjtx-prefix \
~/wsjtx-prefix/src
The CMAKE_PREFIX_PATH variable specifies where CMake should look first
for other packages, the two elements may be different depending where
you have installed Qt and what version you have and where you
installed Hamlib (i.e. the --prefix configure option above in the
hamlib section).
If you already have the fftw3-dev package installed on your system it
may well get selected in preference to the one you built above in the
MacPorts installation. It is unlikely that a prior installation of
libfftw3f is correctly configured for use in a WSJT-X package, the
CMAKE_PREFIX_PATH above is augmented with the MacPorts installation
location (/opt/local) to ensure the correct libfftw3f.dylib and
headers are located.
To build:
cmake --build .
cmake --build . --target install
which installs the WSJT-X application bundle into ~/wsjtx-prefix
Updating and Rebuilding Hamlib
==============================
From time to time new fixes will be pushed to the Hamlib fork
repository integration branch. To pick them up type:
cd ~/hamlib-prefix/src
git pull
To rebuild hamlib with the changed sources:
cd ~/hamlib-prefix/build
make
make install-strip
Updating and Rebuilding WSJT-X
==============================
To update to the latest sources type:
cd ~/wsjtx-prefix/src
svn update
cd ~/wsjtx-prefix/build
cmake --build .
cmake --build . --target install
