[Rdkit-discuss] Struggling with apache + rdkit + django

[Téletchéa S. <ste...@un...>]

Dear all,

I am willing to incorporate some rdkit functionalities using a django 
backend for an internal project
(basically ligand annotation and comparison with docking studies) which 
will be published once ready.

Using the "developper" mode of django and conda I can properly get all 
of them working properly,
but I'm struggling in translating this into a real web service.

For what it counts, I am admin on the machine and for now not a lot of 
services are up so I can test things...

So far I have tried:
- installing rdkit with conda + all required dependencies + wsgi file 
pointing to it
- installing django + dependencies using pip + install from scratch of 
rkdit (Ubuntu Linux 14.04 LTS, 64bits):
     a) using a custom location, works with django manage.py runserver 
but not when launched from apache
     b) building rdkit using different locations (adding 
/etc/ld.so.conf.d/rdkit.conf + ldconfig -> libraries are correctly detected)
     c) adding various path in the wsgi.py configuration file
     d) and many more ...

There are other django services working fine on the machine so it does 
not come from there.
I have also tried to run only this service with no better luck.

I think it is the combination of externally adding LD_LIBRARY_PATH + 
PYTHONPATH that is the culprit,
since the web server responds to the requested address, but after "a 
certain amout of time", I see in apache2 logs:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
End of script output before headers: wsgi.py
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Unfortunately there is no other error message, so I am unable to trace 
the rest of the error.

Does it rings a bell to someone?

Thanks a lot in advance,

Stéphane Téletchéa
