This project is a scratch area for my Python cross compilation work.

One day I'll tidy it up and finish the configuration side of things.

I started this project to make it possible to cross compile GDB with CPython integration.


The build machine can be any of GNU/Linux, Windows and Darwin. The host machine can be any of GNU/Linux, Windows and Darwin. Given the current situation with respect to available cross compilers, the following table illustrates which cross compilation combinations are possible.

Build Machine: GNU/Linux Valid Hosts: GNU/Linux,Windows,Darwin

Build Machine: Windows Valid Hosts: Windows,Darwin

Build Machine: Darwin Valid Hosts: Darwin

To setup a Windows (MinGW-w64 with MSYS) build environment, execute: scripts/windows/BootstrapMinGW64.vbs

It'll ask you: "Do you want Git with your MSYS?" Select Yes. "Install MSYS shell dev tools?" Select Yes. "Install MSYS developer tools?" Select No. "Choose GCC Architecture, Do you want the default GCC to be 64bit?" Select No. "Symlink" Select No.

To get cross compilers: Windows: MinGW-w64 project (Ruben's personal toolchains) Darwin: or

To target Darwin, you will need a fully working MacOSX SDK, usually from an Xcode dmg. Care should to be taken when extracting these as they contain symlinks and many extraction methods fail to handle these correctly.

To build a nest of snakes given the right compilers on your PATH and a Darwin SDK, execute: ./ --python-version=2.7.3,3.3.0 \ --systems=linux-x86,linux-x86_64 \ windows-x86,windows-x86_64 \ darwin-x86,darwin-x86_64 \ --darwin-sdk=PATH_TO_MacOSX10.7.sdk

...cross your fingers and wait a long time.

Something went wrong with that request. Please try again.
