This page explains how to compile Globulation 2 on windows using mingw.

Note: Globulation 2 does not compile with mingw gcc versions 3.2.3, 2.95.3-8 and 3.4.2. But don't worry, gcc version 3.3.1 works and is included in glob2_required_libs_mingw.tar.bz2.

Setting up mingw

(Warning! For the first 3 steps, all install directories must be the exact same. Do not use spaces or capitals for the installation directory. For this guide, we will use the default c:\mingw)

• Download and install MinGW-3.1.0-1.exe into the directory c:\mingw.

• Next, download and install MSYS-1.0.10.exe in the same directory as MinGW (c:\mingw). At the end of the installation, it will ask you if you want to continue with the post-install. Select yes, and yes again when it ask if you have mingw installed. When it ask you to indicate the directory where it is installed, type in c:/mingw (yes, with a forward slash as the program prefers it that way).

• And lastly, download and install msysDTK-1.0.1.exe in the same directory as mingw and msys (c:\mingw)

Compiling Prerequisites

• Download glob2_required_libs_mingw.tar.bz2 from http://globulation2.org/dev/glob2_required_libs_mingw.tar.bz2 and put them in the home directory of mingw (c:\mingw\home\XXX\ where XXX is the username)

• Double click the MSYS icon that has been placed on your desktop during MSYS's installation.

• Go in the directory where you put the glob2_required_libs_mingw.tar.bz2 (for example cd ~) and untar the libraries like this :

tar jxf glob2_required_libs_mingw.tar.bz2 -C /

• Download boost c++ precompiled libraries :

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

• 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 /usr/include && mv boost/lib/* /usr/lib

• To allow the important command "make" to run, use the following command:

mv /usr/bin/mingw32-make.exe /usr/bin/make.exe

• Finally, download and install Mercurial locally so the command hg will work. Use the latest premade binary available from http://mercurial.berkwood.com/ . When you get to the end of the install, make sure you check "add mercurial to your computers search path" or something similar. And now you are ready to go.

Compiling Globulation 2

Compiling from released source code

• Download and extract the release to c:\mingw\home\XXX\ (where XXX is the username), then run:

mv glob2-0.8.xx glob2_release

• Open glob2_release/configure.in and 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 -logg -lwsock32 /lib/libvorbisfile.a /lib/libvorbis.a /lib/libogg.a"

• In order for compiling to work properly, open the mingw console, and run the following commands:

cd glob2_release

(note there is a . at the end of the following command)

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

• Go to the bootstrap file, right click, hit save page as, save it to your computer, the move it to the folder glob2_release (in c:\mingw\home\xxx\glob2_release)

• Now to start compiling globulation 2. Don't worry about the warnings. If something is wrong, it will grind to a halt and it will let you know why:

./bootstrap && ./configure && make

• To make the executable smaller in size, run the following command:

strip ./src/glob2.exe

Compiling from Mercurial

• Download Globulation 2 from mercurial:

hg clone http://hg.globulation2.org/glob2/

• Open glob2/configure.in and 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 -logg -lwsock32 /lib/libvorbisfile.a /lib/libvorbis.a /lib/libogg.a"

• Before compiling glob2, run these commands from the mingw console:

cd glob2

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

• Now to start compiling globulation 2. Don't worry about the warnings. If something is wrong, it will grind to a halt and it will let you know why:

./bootstrap && ./configure && make

• To make the executable smaller in size, run the following command:

strip ./src/glob2.exe

• Finally, to get the data, maps, and campaigns needed to play the game, run the following commands:

./syncdata

./syncmaps

Testing Globulation 2 on windows

• Download glob2_windows_runtime.tar.bz2

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

• Extract it with :

tar jxf glob2_windows_runtime.tar.bz2

• Copy the folders data/, maps/, and campaigns/ and the files AUTHORS and COPYING to glob2_runtime/, overwriting any existing files

• Copy glob2.exe which is in the src directory (glob2/src/) to glob2_runtime/

• Run glob2.exe from the glob2_runtime directory and play :)
