1 - Pyrex Pyrex Builder provides a straight-forward interface which allows you to identify files (.c, .h, and .pyx), frameworks, and compiler flags needed for the module. From there, a single button click will preform all the compiling, linking, and bundling tasks automatically. The build settings can also be saved, and loaded later; further reducing time spent creating modules. License: Freeware OS: Mac OS X 10.3 Size: 4.16 MB
