python-2.1
linux-2.2, others?

the freeze tool does not export global symbols. As a
result the frozen executable fails with unresolved
symbols in shared objects.

fix: include the LINKFORSHARED flag in freeze.py:

I think this patch will fix most of the "freeze fails" reports and requests in newsgroups. The bug itself is still in 2.2 and 2.1.2 :-(

This seems to have bene found on Linux. While the patch
looks reasonable to me, I am not in a position to test. Can
anyone else with a Unix background tell me this seems
reasonable?

Is there a test case I can use to trigger this error?

Thanks for reporting. This problem is already fixed in the CVS.
