== Buidling Mussa on Windows ==

Building Mussa on Windows takes a bit of effort, which is why we provide pre-built binary installers. This section contains additional Windows specific information about building Mussa in windows.

[http://www.mingw.org/ MingGW] Qt4 on windows requires the MinGW compiler. Thankfully the Qt installer will offer to install it for you. The CMake scripts do assume that MinGW and boost are being installed into the default locations of C:\MinGW and C:\Boost. If you install them elsewhere you will need to adjust several CMake variables.

 You'll also probably want to put MinGW, CMake, and darcs on your system path. [http://support.microsoft.com/default.aspx?scid=kb;en-us;310519 How To Manage Environment Variables in Windows XP]

== Boost Libraries ==

For some reason (haven't bothered to look into the details yet), boost builds some of the libraries with .lib, but mingw looks for .a, so, it's required to copy/rename a few libraries to have the .a extension. Below is a list of command prompt commands to make copies of the files needed by Mussa.

{{{
copy C:\Boost\lib\libboost_filesystem-mgw-s.lib C:\Boost\lib\libboost_filesystem-mgw-s.a
copy C:\Boost\lib\libboost_program_options-mgw-s.lib C:\Boost\lib\libboost_program_options-mgw-s.a
copy C:\Boost\lib\libboost_serialization-mgw.lib C:\Boost\lib\libboost_serialization-mgw.a
copy C:\Boost\lib\libboost_unit_test_framework-mgw-s.lib C:\Boost\lib\libboost_unit_test_framework-mgw-s.a
}}}

== Python Libraries ==

Because boost python bindings haven't been updated to Python 2.5 yet, the Python features of Mussa still require Python 2.3 or Python 2.4. If you get an error such as:

{{{
Linking CXX executable mussagl.exe
CMakeFiles/mussagl.dir/qui/mussagl.obj(.text+0xa56): In function `main':
C:/proj/mussa/qui/mussagl.cpp:102: undefined reference to `_imp__PyErr_Print'

}}}

It probably means you are trying to link against Python 2.5. Download Python 2.4 and tell cmake to use Python 2.4.
