Yes, the main program uses wxWidgets (and the same exact version as
the plugin).

However, for distribution reasons, we now build wxWidgets statically.  Are
you
thinking that if we built wxWidgets as a shared library and used the same
shared library in the main app as in the plugin, then I wouldn't have the
problem?

If so, that makes sense.  I think I'll just avoid --no-undefined for plugins
that
use wxWidgets instead since our lives got a lot simpler once we started
linking statically.

Thanks for replying,
