Thanks Graham. i have rebuilt my virtualenv. The first thing that I am
doing is:
./configure --prefix=$PYTHON_INSTALL_DIR --enable-shared
So now my python 2.7.2 is built with enable-shared. I have the problem that
now I need to tell the system where to find the python library. I do it
like this:
export LD_LIBRARY_PATH=/usr/local/python/2.7.2/lib:$LD_LIBRARY_PATH
Without this, I can not even run python (which I suppose is expected).
There is probably a better way than setting LD_LIBRARY_PATH here and there,
but I do not know it.
So this is working, everywhere, *except* within apache: the python started
by apache can not find the libpython library. I have modified
the /etc/init.d/apache2 apache, adding the export LD_LIBRARY_PATH command
at the top of the file, but apache is still unable to find it. I get this
error:
$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2
apache2: Syntax error on line 204 of /etc/apache2/apache2.conf: Syntax
error on line 1 of /etc/apache2/mods-enabled/wsgi.load: Cannot load
/usr/lib/apache2/modules/mod_wsgi.so into server: libpython2.7.so.1.0:
cannot open shared object file: No such file or directory
...fail!
/usr/lib/apache2/modules/mod_wsgi.so exists, and has just been created:
$ ls -l /usr/lib/apache2/modules/mod_wsgi.so
-rw-r--r-- 1 root root 214591 2012-08-02 14:29
/usr/lib/apache2/modules/mod_wsgi.so
Do you know why apache can not find the libpython library? Can you suggest
a workaround?
Thanks,
Daniel
