Just had to recompile apache. Thanks for all the help. -----Original Message----- From: mod_python-bounces at modpython.org [mailto:mod_python-bounces at modpython.org] On Behalf Of Sean Glover Sent: Tuesday, April 24, 2007 8:01 PM To: mod_python at modpython.org Subject: FW: [mod_python] mod_python,python_handler error "Can't get/create interpreter" Looks like 'hashlib' and '_hashlib' alike are installed ok.

Problem is that new Python 2.5 'hashlib' module is the one that is loading '_md5' module. The 'hashlib' module being required by 'urllib2'. The thing is that 'hashlib' shouldn't be trying to import '_md5' if the '_hashlib' module imports okay from 'hashlib', which is what it should use these days instead of '_md5'. What do you get if you try importing '_hashlib' from command line Python. If that doesn't work then your Python installed is borked in some way and you will need to work out how to get 'hashlib' module to import successfully from command line Python before you can get any further. Note that if 'hashlib' does import okay from command line, the problem may be that '_hashlib' has shared library dependencies that can't be resolved when imported under Apache. In that case you will need to run: ldd _hashlib.so from Python library directory and work out what libraries it uses and where they are. If they are in a non standard location then you may have to set directory in LD_LIBRARY_PATH for Apache to tell it where they are. Ideally Python would be rebuilt while setting LD_RUN_PATH in environment with that non standard library location so that directory gets embedded in '_hashlib.so'. Hopefully that makes half sense. :-) Graham > Error: > > [Mon Apr 23 20:21:28 2007] [error] make_obcallback: could not call init.\n > Traceback (most recent call last): > File "/usr/local/lib/python2.5/site-packages/mod_python/apache.py", line > 937, in init > from mod_python import importer > File "/usr/local/lib/python2.5/site-packages/mod_python/importer.py", line > 24, in <module> > from mod_python import publisher > File "/usr/local/lib/python2.5/site-packages/mod_python/publisher.py", > line 50, in <module> > from cache import ModuleCache, NOT_INITIALIZED > File "/usr/local/lib/python2.5/site-packages/mod_python/cache.py", line > 27, in <module> > import urllib2 > File "/usr/local/lib/python2.5/urllib2.py", line 88, in <module> > import hashlib > File "/usr/local/lib/python2.5/hashlib.py", line 104, in <module> > md5 = __get_builtin_constructor('md5') > File "/usr/local/lib/python2.5/hashlib.py", line 31, in > __get_builtin_constructor > import _md5 > ImportError: No module named _md5 > [Mon Apr 23 20:21:28 2007] [error] get_interpreter: no interpreter callback > found. > [Mon Apr 23 20:21:28 2007] [error] [client 76.64.190.137] python_handler: > Can't get/create interpreter., referer: http://randonom.com/test/python/ > > Sean > > -----Original Message----- > From: Graham Dumpleton [mailto:graham.dumpleton at gmail.com] > Sent: Monday, April 23, 2007 7:09 PM > To: Sean Glover > Cc: mod_python at modpython.org > Subject: Re: [mod_python] mod_python, python_handler error "Can't get/create > interpreter" > > On 24/04/07, Sean Glover <seanglover at sympatico.ca> wrote: > > [Mon Apr 23 18:52:47 2007] [error] make_obcallback: could not call init.\n > > Traceback (most recent call last): > > File "/usr/local/lib/python2.5/site-packages/mod_python/apache.py", line > > 937,in init > > from mod_python import importer > > File "/usr/local/lib/python2.5/site-packages/mod_python/importer.py", > line > > 24, in <module> > > from mod_python import publisher > > File "/usr/local/lib/python2.5/site-packages/mod_python/publisher.py", > > line 50, in <module> > > from cache import ModuleCache, NOT_INITIALIZED > > File "/usr/local/lib/python2.5/site-packages/mod_python/cache.py", line > > 27, in <module> > > import urllib2 > > File "/usr/local/lib/python2.5/urllib2.py", line 88, in <module> > > import hashlib > > File "/usr/local/lib/python2.5/hashlib.py", line 104, in <module> > > md5 = __get_builtin_constructor('md5') > > File "/usr/local/lib/python2.5/hashlib.py", line 31, in > > __get_builtin_constructor > > import _md5 > > ImportError: No module named _md5 > > [Mon Apr 23 18:52:47 2007] [error] get_interpreter: no interpreter > callback > > found. > > [Mon Apr 23 18:52:47 2007] [error] [client 76.64.190.137] python_handler: > > Can't get/create interpreter. > > And there be the real problem.
