what do i need to do so that mod_wsgi will find libmysqlclient.16.dylib? (osx 10.7 with apache mod_wsgi)
- by compound eye
I am trying to run django on osx 10.7 (lion) with apache mod_wsgi and virtualenv.
My site works if I use the django testing server:
(baseline)otter:hello mathew$ python manage.py runserver
but it doesn't work when I run apache. The core of the error seems to be
Library not loaded: libmysqlclient.16.dylib
I think its to do with the path apache is using to locate libmysqlclient.16.dylib
when I run otool in the lib directory it looks good
otter:lib mathew$ pwd
/usr/local/mysql/lib
otter:lib mathew$ otool -L libmysqlclient.16.dylib
libmysqlclient.16.dylib:
libmysqlclient.16.dylib (compatibility version 16.0.0, current version 16.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1)
but from outside it can't find it
otter:lib mathew$ cd /
otter:/ mathew$ otool -L libmysqlclient.16.dylib
otool: can't open file: libmysqlclient.16.dylib (No such file or directory)
if i manually set DYLD_LIBRARY_PATH otool works
otter:lib mathew$ DYLD_LIBRARY_PATH=/usr/local/mysql/lib otter:lib
mathew$ otool -L libmysqlclient.16.dylib libmysqlclient.16.dylib:
libmysqlclient.16.dylib (compatibility version 16.0.0, current
version 16.0.0) /usr/lib/libSystem.B.dylib (compatibility version
1.0.0, current version 125.0.1)
When I run the django testing server, my .bash_profile sets up the virtualenv and the path to the mysql dynamic library
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH
export PATH
When i run apache it finds my virtualenv paths, but it doesn't seem to find the dynamic library path.
I tried adding this path to /usr/sbin/envvars
DYLD_LIBRARY_PATH="/usr/lib:/usr/local/mysql/lib:$DYLD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH
and to /private/etc/paths.d/libmysql
/usr/local/mysql/lib
then restarted the machine
but that has not changed the error message.
Error loading MySQLdb module: dlopen(/usr/local/python_virtualenv/baseline/lib/python2.7/site-packages/_mysql.so,
2):

I don't think is a permissions issue:

What do i need to do so that mod_wsgi will find libmysqlclient.16.dylib?
apache and mysql are both 64 bit:
otter:lib mathew$ file /usr/sbin/httpd /usr/sbin/httpd: Mach-O
universal binary with 2 architectures /usr/sbin/httpd (for
architecture x86_64): Mach-O 64-bit executable x86_64 /usr/sbin/httpd
(for architecture i386): Mach-O executable i386 otter:lib mathew$
otter:lib mathew$ file /usr/local/mysql/lib/libmysqlclient.16.dylib
/usr/local/mysql/lib/libmysqlclient.16.dylib: Mach-O 64-bit
dynamically linked shared library x86_64
