[PYTHON-CRYPTO] M2Crypto build error - _lib.h:5: error: redefinition of typedef 'Py_ssize_t'

[Philip Kershaw]

Thanks for the help.   

0.18.2 still breaks for me unfortunately but I can build by commenting out:

/*
#if PY_VERSION_HEX < 0x02050000
typedef int Py_ssize_t;
#endif
*/

My OpenSSL version is 0.9.8f.   The system is 32-bit I think:

# uname -a
Linux ndg 2.6.9-42.0.2.ELsmp #1 SMP Thu Aug 17 18:00:32 EDT 2006 i686 i686 
i386 GNU/Linux

I've copied in the easy_install output again below...

Cheers,
Phil
