Hi,
A question from a new mod_python user:
When I run within an otherwise working apache2/mod_python, if my script imports MySQLdb I get a dyld compability version error:
File "/Users/jim/Sites/WatchEvents.py", line 97, in ?
import MySQLdb, pickleFile "/opt/local/lib/python2.4/site-packages/MySQLdb/__init__.py", line 27, in ?
import _mysql
ImportError: Failure linking new module: /opt/local/lib/libssl.0.9.7.dylib: dyld: /opt/local/apache2/bin/httpd version mismatch for library: /opt/local/lib/libssl.0.9.7.dylib (compatibility version of user: 0.9.7 greater than library's version: 0.9.0)
Now, /opt/local/lib/libssl.0.9.7, like /opt/local/apache2/bin/httpd, and the installed copy of _mysql.so report having "(compatibility version 0.9.0, current version 0.9.7)". [Perhaps it matters that /usr/local/lib/libssl.0.9.7 has "(compatibility version 0.9.7, current version 0.9.7)", but I don't see where it's used] As I understand it [from man ld] this sort of dyld error should only occur when the program compatibility version is > the lib version -- yet the lib is version 0.9.7, >= all the compatibility versions in play.
Can anyone see what I'm missing?
I should point out that MySQLdb was installed in the usual way using setup.py, and I did redo this after fully updating the darwinports tree and rebuilding apache2. Apache2, mod_python, and python24 all come from darwinports. MySQLdb is of course installed, as is MySQL from Server Logistics. [Perhaps the MySQL version is the problem? Because the MySQL is not from darwinports, I had to hack the MySQLdb setup.py file to get it to use the darwinports version of libssl and thus have exactly the same compatibility version. Should I have hacked something more?] This is on lhe latest MacOS X 10.3.8.
All these components work fine if I don't import MySQLdb, and MySQLdb works fine in the python interpreter.
If anyone has any suggestions I'd greatly appreciate them. And BTW I'd be happy to link statically if that's doable/better/easier.
Jim
PS: according to locate (after running locate.update) the only libssl are:
