Thanks for the implementation, can't wait to try. But again I'm running into
some problems.
I installed the c stl with configure --prefix='/home/me/libcalg'
Changed the setup.py:
#!/usr/bin/env python
# python setup.py build_ext --inplace
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext = Extension(
"cy_hash",
["cy_hash.pyx"],
language="c",
include_dirs=['/home/me/libcalg/include/libcalg-1.0'],
library_dirs=['/home/me/libcalg/lib'],
libraries=['calg'], #also tried 'libcalg/calg'
cmdclass = {'build_ext': build_ext}
)
setup(
cmdclass={'build_ext': build_ext},
ext_modules=[ext]
)
When I run python setup.py build_ext --inplace
I get a warning: /usr/lib/python2.5/distutils/extension.py:133: UserWarning:
Unknown Extension options: 'cmdclass'
warnings.warn(msg)
When I run python -c 'import cy_hash as cc; cc.test()'
I get: ImportError: libcalg.so.0: cannot open shared object file: No such
file or directory
The file is compiled and ready in '/home/me/libcalg/lib' and is rwx
accessible for me. What's going on here?

Thanks for the implementation. I noticed that your compare was only
comparing pointers, so if you had two equal strings at different
memory addresses it wouldn't find them (which may or may not be what
you'd want) Also, your pointers would go out of scope as soon as test
ended (so you couldn't return ht and use it later).
I built on what you had to get a float -> float hashtable. Note that
this technique only works since the float value fits inside a void*,
anything bigger and you'd have to allocate memory manually to stick
it into the hashtable.
