Hi Paul,
FWIW - I've got some classes in both, and the second one to load is
calling into the code from the first one to load.
Is there a way to keep each one from seeing the classes/code in the
other?
there's no way to prevent this in Objective C at the moment (google for
"flat namespace"). Defining common classes in one plugin and having
other plugins counting on that plugin to be loaded is probably asking
for trouble.
The two ways to get around this problem are:
1) if you can, put all of your plugin classes into a single bundle. We
use this technique ourselves; I can explain how it works if you'd like.
2) if you can't do #1, put the common classes in a shared framework, and
have both plugins link to the framework.
Really, the only reason not to do #1 is if the two plugins are two
separate products, sold separately, and the user could legitimately have
one installed but not the other. But it sounds like if that were the
case, what you're doing wouldn't work (plugin B depends on plugin A,
right?).
I should have been more clear. They are independent plugins that happen
to have some C++ classes in each that are named the same.
Say I have a C++ class GlobalStuff in each one, and it's declared
statically. The second one to load is calling into the methods of the
instance in v1, even though they are declared statically. This doesn't
happen with similar code in other hosts.
