Import Error: Undefined Symbol after compiling from source #3

I experience an error when starting log2timeline.py after compiling libfwsi from git into pyfwsi on an arch linux system.

> log2timeline.py --version
Traceback (most recent call last):

ImportError: /usr/lib/python2.7/site-packages/pyfwsi.so: undefined symbol: libfwsi_file_entry_extension_get_access_time

The package was compiled via:

env PYTHON=python2.7 PYTHON_VERSION=2.7 ./configure --enable-python;
make;
sudo make install;
cd pyfwsi;
python2.7 setup.py build; 
sudo python2.7 setup.py install;

The file /usr/lib/python2.7/site-packages/pyfwsi.so has been created through the compiling steps.

Sorry if this may be a stupid question, but I compiled libsigscan just before that, and experienced no problems with the same command.

Okay, funny how problems solve themselves once you formulate them in writing for others. After spending 2 hours trying to compile the library, I changed to compile command to env PYTHON=python2.7 ./configure --enable-python --prefix=/usr; and make ; and sudo make installand it worked.

Thanks again for the nice software you created, and sorry for spamming your issue tracker :-)

Nope sounds familiar ;) It helps because you need to make what you are doing more verbose and hence think about the problem from a different perspective.

Good to hear you have solved it. Sounds to me you might have 2 copies of libfwsi on your installation check /usr/local/lib and /usr/lib (or equiv).
