I have install freeswitch and wikipbx. But When I start web-server
#python manage.py runserver 0.0.0.0:8000

in browser I am getting this :

ViewDoesNotExist at /
Could not import wikipbx.wikipbxweb.views. Error was: No module named ESL

I am also not able to build ESL module
Build ESL with Python

I changed directory to libs/esl directory under freeswitch source tree & try to run following command.
$ make pymod

but I got error

As described in WSGI configuration docs, you should have in your apache config something like:

WSGIPythonPath /usr/src/wikipbx:/usr/src/django:/usr/src/freeswitch/libs/esl/python

The last part of that path contains ESL python bindings directory. I suppose you've missed this step. The message from compiler is not an error - it just tells that you've compiled that library.

1. Is python2.6 the default version installed on your OS? What does this command return:

python --version

2. Make sure ESL library is built:

ls /usr/src/freeswitch/libs/esl/python/_ESL.so

Looks like that's the case, but an extra check won't hurt.

3. Run python with PYTHONPATH environment variable used for wikipbx:

PYTHONPATH=/usr/src/wikipbx:/usr/local/lib/python2.6/dist-packages/django:/usr/src/freeswitch/libs/esl/python python2.6

Execute this command:

import ESL

Do you get any errors?

Thanks for the reply.

I followed the steps. I didn't get any error. My python version is 2.6.
I copied libs/esl/python/ESL.py & _ESL.so to /usr/local/lib/python2.6/dist-packages/ and error is solved.
have I done any mistake with that ? is it correct ?

No, that's fine. The only problem you can have from this is if someday freeswitch will change event socket protocol to something incompatible with current version and you update freeswitch but don't copy ESL libs from the new version. But I think that it's a very unlikely situation.

Which version of mod_wsgi do you run? It looks like there's some change with its configuration directives, otherwise I don't understand why WSGIPythonPath didn't work.

My mod_wsgi (libapache2-mod-wsgi) version is 2.3. I have install through synaptic package manager in ubuntu 9.04.

I've seen cases where WSGIPythonPath seemed to be ignored and I had to manually add to sys.path in the .wsgi script. Unfortunately I didn't write down the exact mod_wsgi / python versions.

According to mod_wsgi docs, starting from v2.0 it doesn't work it daemon mode. But there's parameter for daemon mode directive that lets you set python path instead.
