MXE (M cross environment)

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
