Windows Cross Compile Guide

Preface

This guide describes how to cross-compile Warzone for Windows on Linux (starting with r8841 for trunk, r8851 for 2.3, older instructions below). Instructions are for a Debian unstable system, but should be easy to adapt for other distros.

Requirements

You need the following packages: subversion, nsis (to build an installer), mingw32-runtime, mingw32-binutils, and either the old mingw32 or gcc-mingw32 (at least version 4.4.2-2), plus of course the Warzone source and the usual build tools (autoconf, automake, make... using ​ccache is not required, but very recommended). All library dependencies are downloaded during the build process.

Configuration

For preparation, run "./autogen.sh", and to build an installer with correct translations "./configure && make && make -Cpo update-po && make distclean" (this is necessary until #1473 is fixed).

You can configure the build with a win32/__BUILD_CONFIG.USER file, where you can set two options. DOWNLOADS specifies where downloaded source packages are saved, default is win32/downloads. You can set this to some other directory to not redownload the files after e.g. cleaning the complete source tree. HOST_TRIPLET depends on the configuration of the used cross-compiler, on Debian unstable, this would be HOST_TRIPLET=i586-mingw32msvc which is already the default, you only need to set this if you need a different prefix. These options can also be set when calling the build script: "win32/__BUILD_SCRIPT HOST_TRIPLET=i586-mingw32msvc".

Building etc.

The whole process is handled by win32/__BUILD_SCRIPT (run it like that from the top of the source tree, or as ./__BUILD_SCRIPT from the win32 dir). For a simple build of the game you don't need any options (except the host triplet mentioned above). To build an installer, you also need the nsis package, and the --enable-installer option. If you want to use other options for the configure script, just pass them to the build script.

Note: If you make a version for other people to use, please add --with-distributor=<your name/website>, so that we know where builds are from when people send us crashdumps.

After a successful compile run, the binary is located in win32/build/src/warzone2100.exe, the installer in win32/build/pkg/nsis/.

To remove the compiled files use the clean option to the script, very-clean also removes the downloaded sources. Those are saved in win32/downloads.
