neo_cgi.so: undefined symbol: NERR_PARSE
Marcio Marchini
Can anybody help shed some light into this problem, please?
Backgound:
* I have installed Trac under Windows in the past, it was easy
* A colleague installed Trac under Red Hat, he suffered but it was
working fine
* We moved to a new server (new hardware) and I am trying to get Trac up
and running on the new hardware
The error:
Traceback (most recent call last):
File "/usr/local/lib/python2.5/site-packages/trac/web/main.py", line

TracError: ClearSilver not installed
(/www/svn.foo.org/egg-cache/clearsilver-0.10.1-py2.5-linux-i686.egg-tmp/neo_cgi.so:
undefined symbol: NERR_PARSE)
I believe I have multiple versions of Clearsilver due to a combination
of rsyncing files from the old server and/or my attempt to recompile
Clearsilver from source and/or my attempt o install it with easy_insall.
Here:
[root@mail clearsilver]# find / -name neo_cgi.so -print
/www/svn.foo.org/egg-cache/clearsilver-0.10.1-py2.5-linux-i686.egg-tmp/neo_cgi.so
/usr/lib/python2.3/site-packages/neo_cgi.so
/usr/local/lib/python2.5/site-packages/neo_cgi.so
/usr/local/src/clearsilver-0.10.4-oldserver/python/neo_cgi.so
/usr/local/src/clearsilver-0.10.4-oldserver/python/build/lib.linux-i686-2.5/neo_cgi.so
/usr/local/src/clearsilver-0.10.4/python/neo_cgi.so
I believe the old server was using 0.10.4. Since I could not re-run
./configure, I renamed teh dir to
/usr/local/src/clearsilver-0.10.4-oldserver and untar'ed again into
/usr/local/src/clearsilver-0.10.4 again and re-ran configure etc.
I believe it was teh easy_install attempt which installed the older
version, 0.10.1, but I could be wrong.
Here's teh dates/details for teh different ones:

[root@mail bugzilla]# python --version
Python 2.5.1
Even if I delete the egg cache, it comes back. Where is it getting that
stuff from? SHouldn't my ./configure for clearsilver have replaced this
stuff?
Can anybody bring some light into this please? I am not a Python expert
and by no means a Clearsilver expert either. easy_install does not seem
able to uninstall, so I ran "rpm -e clearsilver" and re-installed from
sources (0.10.4) using configure. But the problem persists.
Thanks,
marcio

For the record, I am replying to my own message jut to share how I
solved the problem, hoping it may help others. The solution was to go to
Clearsilver 0.10.5, with these steps:
Make sure you remove any clearsilver eggs from
/usr/local/lib/python2.5/site-packages. Also any neo_cgi.so in there.
Now this:
cd /usr/local/src/clearsilver-0.10.5
./configure --with-python=/usr/local/bin/python
make
make install
cd python
python setup.py bdist_egg
cp
/usr/local/src/clearsilver-0.10.5/python/dist/clearsilver-0.10.5-py2.5-linux-i686.egg
/usr/local/lib/python2.5/site-packages
chmod 644
/usr/local/lib/python2.5/site-packages/clearsilver-0.10.5-py2.5-linux-i686.egg
restart apache
