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

Setting up Python, Scons, and Mercurial

• Download and install python-2.5.1.msi into the directory "C:\Python25" (default install is Python25, don't change this)
• Download and install scons-0.97.win32.exe into the same directory as the python install (C:\Python25\)
• Download and install Mercurial-0.9.4-f48290864625.exe locally (to any directory, preferably default C:\Mercurial though) so the command hg will work. 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.

Setting up MinGW and MSYS

• Download and install MinGW-5.1.3.exe into the directory c:\mingw (lower case) and select the MinGW base tools and g++ compiler packages only during the installation selection process
• And, download and install MSYS-1.0.10.exe into the directory c:\msys\1.0\ (lower case). 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).

Compiling Prerequisites

• Download glob2_required_libs_mingw-scons.tar.bz2 and put it in the home directory of msys (c:\msys\1.0\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-scons.tar.bz2 (for example cd ~) and untar the libraries using the command below. This process could take a while:

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

Compiling Globulation 2

Step 1: Preparing for a compile

Compiling from Released source code

• Download and extract the release to c:\msys\1.0\home\XXX\ (where XXX is the username), then run (changing the version numbers):

mv glob2-x.x.xx glob2_source

Compiling from Mercurial source files

• Download Globulation 2 from mercurial:

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

• Extract the master (the stable branch) from the mercurial download (this can also be used to extract other branches, such as core_rewrite_2007):

hg clone -r master glob2 glob2_source

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

cd glob2_source
hg update tip
./syncdata
./syncmaps

Step 2: Continue compiling

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

cd glob2_source

• 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.

scons

If there are any problems, run it one more time using the following line. If problems persist, write a bug report.

scons --no-cache mingw-true

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

strip ./src/glob2.exe

Testing Globulation 2 on windows

• Drag the required dll's into the root source folder:

cd glob2_source
cp -a /local/bin/SDL.dll /local/lib/*.dll .

Running Globulation from compiled source

• Drag the glob2 executable into the root source folder:

cp -a ./src/glob2.exe .

• Run glob2.exe from the glob2_source directory and play :)

Building a Globulation 2 NSIS installer

• Download and install nsis-2.29-setup.exe into all its default installation folders (just keep clicking Next).
• Go to (using windows explorer) the windows folder, located inside the glob2_source directory and drag and drop win32_installer.nsi onto the NSIS icon to initialize the build process.
• If all things go well, an exe ready for installation on windows computers is now ready within the windows folder. Test it (install and play), and if it works, send it to your friends ;)

Conclusion

That concludes this Mingw compilation tutorial. If you have any problems, please write a bug report and one of the Windows maintainers should be able to help you. More information on bug reports can be found at the Bug Reports page. Happy compiling.
