Impossible to run cython module directly?

I have a very basic test script for cython test1.pyx: ``` def do_something(f): return f def main(): f = 1 print do_something(f) if __name__ == "__main__": main() ``` Which I compile with: ``` cython test1.pyx gcc -Wall -O2 -g -lm -shared -pthread -fPIC -fwrapv -fno-strict-aliasing -Iinclude/python2.6 -o test1.so test1.c ``` And it works: ``` ./bin/python -c "import test1; test1.main()" 1 ``` But calling it directly as a module doesn't work: ``` ./bin/python -m test1 /mypath/bin/python: No code object available for test1 ``` Why does this not work? How can I get it to work to directly call a cython script? Cython version 0.12.1
