Mingw cross compilation

This page explains how to build and test globulation2 for windows on a Debian GNU/Linux operating system.

For any problems or suggestions, don't hesitate to contact me. Ion bidon

Remark: if you use another mingw compiler than the one requested to download in this page, compilation might fail.

Compile globulation2 for windows on Debian using mingw

1. install mingw :

   apt-get install mingw32 mingw32-binutils mingw32-runtime

2. install wine from the wine repository :

   Change the file /etc/apt/sources.list and add

   deb http://wine.sourceforge.net/apt/ binary/

   apt-get update && apt-get install wine && ln -s /usr/bin/wine /usr/bin/wine-auto

3. create the following directory :

   mkdir libs

4. download glob2_required_libs_mingw.tar.bz2 :

   wget http://globulation2.org/dev/glob2_required_libs_mingw.tar.bz2

5. untar the libraries like this :

   tar jxf glob2_required_libs_mingw.tar.bz2 -C ./libs

6. download boost c++ precompiled libraries :

   wget http://viral.media.mit.edu/releases/boost-1.33.1-mingw-bin.tar.gz

7. manually install boost c++ with the following commands :

   tar zxf boost-1.33.1-mingw-bin.tar.gz

   mv boost/include/boost-1_33_1/boost ./libs/include

   mv boost/lib/* ./libs/lib

8. Download a mingw compiler that works :

   wget http://mirrors.ircam.fr/pub/videolan/testing/win32/mingw-gcc3.3.1-linux-crosscompiler.tar.bz2

9. As root, unpack the compiler (it will create a mingw directory in /usr/local) :

   tar jxf mingw-gcc3.3.1-linux-crosscompiler.tar.bz2 -C /

10. From the directory containing the libs directory, type the following :

    export CC="i586-mingw32msvc-gcc"

    export CXX="i586-mingw32msvc-g++"

    export CFLAGS="-I$PWD/libs/include $CFLAGS"

    export CXXFLAGS="-I$PWD/libs/include -I$PWD/libs/include/freetype2 $CXXFLAGS"

    export LDFLAGS="-L$PWD/libs/lib $LDFLAGS"

    export PATH=/usr/local/mingw/bin:/usr/i586-mingw32msvc/bin:$PWD/libs/bin:$PATH

    rm ./libs/bin/auto*

    change the third line of ./libs/bin/sdl-config from prefix=/usr to point to the libs directory (hard path) or from the directory containing the libs directory, type:
    

    perl -e '$pwd=%ENV->{PWD};$tmp="";while(<>){chomp;if(s/prefix=\/usr/prefix=/g){$_="prefix=".$pwd."/libs"}$tmp.= $_."\n"}open(FI,"+< ./libs/bin/sdl-config");print FI $tmp;' ./libs/bin/sdl-config

11. download glob2 cvs (as anonymous for example) :

    export CVS_RSH="ssh"

    cvs -z3 -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/glob2 co glob2

    cd glob2

    cp ../libs/bin/SDL.dll ../libs/bin/libvorbis-0.dll ../libs/bin/libogg-0.dll ../libs/bin/libvorbisenc-2.dll ../libs/bin/libfreetype-6.dll .

    cp ../libs/lib/libvorbisfile.a ../libs/lib/libvorbis.a ../libs/lib/libogg.a .

    Open the configure.in file, find:

    CPPFLAGS="$CPPFLAGS $SDL_CFLAGS"

    and replace with:

    CPPFLAGS="$CPPFLAGS $SDL_CFLAGS -I/usr/include/freetype2" LDFLAGS="$LDFLAGS `sdl-config --libs` -lSDL_ttf"

    In the same file, find:

    LIBS="$LIBS -logg -lwsock32"

    and replace with:

    LIBS="$LIBS -lwsock32 ../libvorbisfile.a ../libvorbis.a ../libogg.a"

12. compiling glob2 :

    ./bootstrap

    ./configure --host=i586-mingw32msvc

    make

13. To make the executable smaller :

    strip ./src/glob2.exe

Test globulation2 for windows on Debian

1. download glob2_windows_runtime.tar.bz2

   wget http://globulation2.org/dev/glob2_windows_runtime.tar.bz2

2. extract it with :

   tar jxf glob2_windows_runtime.tar.bz2

3. go in the glob2 directory where you have compiled glob2 and type

   ./syncdata

   ./syncmaps

4. copy the content of glob2/data/ to glob2_runtime/data/
5. copy the content of glob2/maps/ to glob2_runtime/maps/
6. copy glob2.exe which is in the src directory (glob2/src/) to glob2_runtime/
7. run wine glob2.exe from the glob2_runtime directory and play :)
