[C++-sig] Problems loading installed extensions: help needed

[Jose Vicente Nunez Zuleta]

Hmmm, thats sounds weird. I mean, why the debug symbols should matter to
the Python interpreter?

Also, renaming the module to pyd should not matter, i guess Python
should be able to load the extension as an 'so'.

Any ideas?

How i can check what Python is trying to load at runtime? (like a
verbose flag)

Thanks,

JV.
