[pypy-dev] Using PyPy as a compiler

[Hart's Antler]

Hello,

I've got the pypy compiler working! see the function at the bottom.  But now i'm having some
problems when importing the module and testing some of its functions.

here's the commands i typed to make the module:
pypy/tool/pyrexc myModule.pyx
gcc -c -fPIC -I/usr/include/python2.3/ myModule.c
gcc -shared myModule.o -o myModule.so

when i import the module and try isFloatingPoint(None, '0.001') it returns the error below, looks
like it can not find 'contains'  where does contain come from, should i have linked to another
library when making the .so file?

>>> mod.isFloatingPoint(None, '0.001')
Traceback (most recent call last):
