Okay, this is confusing.
This specific problem is usually caused because Oracle libraries are not in a
standard directory location. It is therefore necessary to set DYLD_LIBRARY_PATH
environment variable to say where they reside.
When I did the ‘otool -L’ test on cx_Oracle.so I asked you to ensure you had
unset the DYLD_LIBRARY_PATH environment variable. With that not set, if
DYLD_LIBRARY_PATH was required I would have expected ‘otool -L’ to not be able
to resolve the Oracle library, yet it was.
Even if you hadn’t unset it, it means it was in your environment either way.
This means that when you ran mod_wsgi-express it should have inherited
DYLD_LIBRARY_PATH and it still should find the Oracle libraries when loading
cx_Oracle.so.
Few more things to check.
Find the ‘apachectl’ script that is generated by mod_wsgi-express. Usually it
would be at:
/tmp/mod_wsgi-localhost\:8000\:502/apachectl
What does it have for:
SHLIBPATH=""
if [ "x$SHLIBPATH" != "x" ]; then
DYLD_LIBRARY_PATH="$SHLIBPATH:$DYLD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH
fi
It should probably be the same, but want to check.
Also edit:
/tmp/mod_wsgi-localhost\:8000\:502/envvars
and add to it:
env
This will output to console when running mod_wsgi-express all the environment
variables set.
What does DYLD_LIBRARY_PATH show in that? Are there any other DYLD environment
variables set?
Also trying running mod_wsgi-express with this test WSGI application:
https://raw.githubusercontent.com/GrahamDumpleton/mod_wsgi/develop/tests/events.wsgi
<https://raw.githubusercontent.com/GrahamDumpleton/mod_wsgi/develop/tests/events.wsgi>
What DYLD environment variables get through to the WSGI application.
