Error "Symbol not found: _EVP_DigestFinal_ex"

[marc-fan]

Hi,

I try to compile the new version of pybloomfiltermmap. All seems to work when I launch "python setup.py install", but when I try to import the module, it returns the following error:

MacBook-Pro:axiak-pybloomfiltermmap-70a85e6 root# python
ActivePython 2.6.7.20 (ActiveState Software Inc.) based on

import pybloomfilter
Traceback (most recent call last):

I verify if _EVP_DigestFinal_ex exists in my system:

0000000000056840 T _EVP_DigestFinal

0000000000056840 T _EVP_DigestFinal
00000000000567b0 T _EVP_DigestFinal_ex

I can't undestand where I'm wrong!

Can you help me to solve this problem?
Thanks in advance!

Did you ever fix this? I believe this is a missing dependency and I do not have a mac to test this on.

I'm getting this on Arch Linux x86_64, Linux 3.5.4, with Python 2.7.

>>> import pybloomfilter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/lib/python2.7/site-packages/pybloomfilter.so: undefined symbol: EVP_DigestFinal_ex

I also see EVP_DigestFinal_ex in my libcrypto.so:

$ nm /usr/lib/libcrypto.so | grep DigestFinal
0000000000114d70 T EVP_DigestFinal
0000000000114870 T EVP_DigestFinal_ex

This seems to prevent w3af_gui from starting on my machine.

Hey guys, Please try installing release 0.3.8. I have OS X now but was not able to reproduce this bug. I've included crypto as a library when compiling so that should help...

Thanks axiak, that did fix my issue even though I am not on OS X but Arch Linux. :)
