Alternative to MSYS2

You can try to use gtk-fortran under Windows without MSYS2, but do not expect much support in that case. You can read this interesting page about using "GTK-Fortran with Code::Blocks IDE" under Windows 7 64bits, and also Creating a GUI using GTK3 and gtk-fortran. See also the Fortran Tools document in the Useful links section.

Prerequisites

You will need:

• Fortran compiler (recommended is gfortran 4.6 or higher: included in MinGW http://sourceforge.net/projects/mingw)
• CMake http://www.cmake.org/cmake/resources/software.html
• GTK
  • official version: GTK 2.24 http://www.gtk.org/download/win32.php (for testwin32gtk2 branch)
  • GTK 3.6.1 http://www.tarnyko.net/dl/ (for testwin32gtk3 branch)
• sed http://sourceforge.net/projects/gnuwin32
• PLplot http://sourceforge.net/projects/plplot (optionally)

Install

Install the dependencies manually.

PLplot

Windows binaries of PLplot are not distributed. Therefore you have to build your own binaries (after installation of MinGW and Cmake):

• download from http://sourceforge.net/projects/plplot (latest version is 5.9.9)
• extract the archive
• cd to the extracted archive folder
• mkdir build
• cd build
• cmake -DCMAKE_INSTALL_PREFIX=<installation directory> -DCMAKE_C_COMPILER=gcc -G "MinGW Makefiles" .. (be careful to use NO space in <installation directory>, e.g. C:\Program Files\PLplot will not work!!!)
• mingw32-make
• mingw32-make install
• add <installation directory>\bin, <installation directory>\lib and <installation directory>\lib\plplot5.9.9\driversd to PATH
• add <installation directory>\lib\pkgconfig to PKG_CONFIG_PATH

Known Problems and solutions

• GTK libraries not found after installation: Do you have spaces in the installation directory name? (e.g. C:\Program Files\GTK will not work!!!) - Reinstall GTK in a directory without spaces.
• Some GTK symbols are not found by the linker: Do you have older libgtk versions in PATH before the current version (installed by some other software, e.g. Graphviz)? - Prepend the directory with the current GTK libraries to PATH.

Status

gtk-fortran was successfully tested on the following Windows platforms:

• Windows 7 (32 bits) with gfortran 4.6.0 20110115 (experimental) and the dll of GTK 2.22.1, put in the src directory.
• Windows XP SP3 (32 bits) with gfortran 4.7.2-1 and GTK 2.24
• Windows XP SP3 (32 bits) with gfortran 4.7.2-1 and GTK 3.6.1
