How to compile and link multiple python modules (or packages) using cython?

Question

I have several python modules (organized into packages), which depend on each other. e.g.

• Module1
• Module2: imports Module1
• M

Answer 1

Edit. First two options refer to Cython's specific code, what I've missed is that the question is about pure python modules, so option 3 is the solution.

There are a few options:

1. See this "How To Create A Hierarchy Of Modules In A Package": https://github.com/cython/cython/wiki/PackageHierarchy

2. I prefer the "include" statement: http://docs.cython.org/src/userguide/language_basics.html#the-include-statement I have many .pyx files and they are all included in main.pyx, it's all in one namespace. The result is one big module: http://code.google.com/p/cefpython/source/browse/cefpython.pyx

3. You can compile all your modules at once using setup by adding more than one "Extension":

setup(
    cmdclass = {'build_ext': build_ext},
    ext_modules = [Extension("example", sourcefiles), Extension("example2", sourcefiles2), Extension("example3", sourcefiles3)]
)

4. A more efficent compilation - see here.

setup (
    name = 'MyProject',
    ext_modules = cythonize(["*.pyx"]),
)
