With windows compilation I’ve gotten into a point where I’m able to build _pjsip.c into a pyd file with .Net, but currently when trying to import _pjsip in python causes Exception: Calling pjlib from unknown/external thread.. register external threads with pj_thread_register() do you have any clue where I could be going wrong, or how do I call pj_thread_register() before importing library?

Samenvatting:

SELinux is preventing sip_im_session from loading /usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so which requires text relocation.

Gedetailleerde omschrijving:

The sip_im_session application attempted to load /usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests ( http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. You can configure SELinux temporarily to allow /usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so to use relocation as a workaround, until the library is fixed. Please file a bug report ( http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Allowing Access:

If you trust /usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t '/usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so'"

Fix Command:

chcon -t textrel_shlib_t '/usr/lib/python2.5/site-packages/sipclient-0.3.0-py2.5-linux-i686.egg/pypjua/_pjsip.so'

I checked out trunk cleanly and updated all dependencies. I get the same error under Fedora and FreeBSD; however, under Ubuntu the same procedure results in a working instance.
