Due to a lack of Windows developers, it is a good idea to allow Linux developers to do at least some basic check of their code. This HOWTO explains how to set up cross-compilation. MinGW under Debian ================== First, you need to install the "gcc-mingw-w64" package and get a MPlayer SVN checkout. To get a fully functional build, you need to get a lot of dependencies compiled first. This is outside the scope of this document. Then you need to run ./configure --enable-cross-compile --windres=i686-w64-mingw32-windres --cc=i686-w64-mingw32-gcc and make. To compile a 64-bit Windows binary, use ./configure --enable-cross-compile --windres=x86_64-w64-mingw32-windres --cc=x86_64-w64-mingw32-gcc instead. For files meant to run on a different computer you should usually use --enable-runtime-cpudetection. You should be able to run the generated binary with Wine, if you want to. The steps as command-lines: sudo apt-get install gcc-mingw-w64 svn co svn://svn.mplayerhq.hu/mplayer/trunk MPlayer-mingw cd MPlayer-mingw ./configure --enable-cross-compile --windres=i686-w64-mingw32-windres --cc=i686-w64-mingw32-gcc make Wine ==== First, you need to install the "Wine" package and get a MPlayer SVN checkout. You don't need any dependencies other than those you already have for your Linux build, because the Wine and Linux build will use them together. Configure with ./configure --target=i686-wine --cc="winegcc -m32" --windres=wrc --enable-gui and add any options you normally use for your Linux build, then run make.
