MXE (Aleph One downstream)

This fork patches zziplib and ffmpeg for optimal use within Aleph One. See the Developer Notes for instructions on building Aleph One for Windows.

Original documentation follows.

MXE (M cross environment)

MXE (M cross environment) is a GNU Makefile that compiles a cross compiler and cross compiles many free libraries such as SDL and Qt. Thus, it provides a nice cross compiling environment for various target platforms, which:

• is designed to run on any Unix system
• is easy to adapt and to extend
• builds many free libraries in addition to the cross compiler
• can also build just a subset of the packages, and automatically builds their dependencies
• downloads all needed packages and verifies them by their checksums
• is able to update the version numbers of all packages automatically
• directly uses source packages, thus ensuring the whole build mechanism is transparent
• allows inter-package and intra-package parallel builds whenever possible
• bundles ccache to speed up repeated builds
• integrates well with autotools, cmake, qmake, and hand-written makefiles.
• has been in continuous development since 2007 and is used by several projects
