When I build a swig-generated C extension module against CPython 2.6, and
attempt to load it using cpyext, I get:
/usr/local/pypy-1.5/bin/pypy
>>>> cpyext.load_module('_odirectcmodule.so', 'odirect')
Traceback (most recent call last):
File "<console>", line 1, in <module>
ImportError: unable to load extension module './_odirectcmodule.so':
./_odirectcmodule.so: undefined symbol: PyClass_Type
>>>>
1) Is that the right way to load a C extension module using cpyext?
2) Do I need to recompile the module for pypy?
3) Are there known issues with cpyext and swig?
4) Of swig, Cython, hand-coded C, and ctypes, which is the better bet today
for reliability with use from PyPy?
Thanks!
PS: This is, I believe, a module that really does need some C - it does
bitwise address arithmetic to get page alignment.
