Hi all,
I'm creating a plugin for an application in which is not mine but is
open source so i have the code for it.
What i'm trying to do is to subclass an object that's within the app
and when my plugin is loaded, to pose it as the original object. The
problem is that i'm getting an undefined symbol error when when
compiling my plugin.
I *could* include the header and implementation files of the original
object within my plugin, but this means that if in a future version
this object will change and my plugin will be loaded, both versions
of the object will be loaded and this is not a good thing.
I think it's par for the course when you're trying to write a class-
posing plugin, though. You'll have to release another version of your
plugin for each future release of the app that is incompatible at the
binary level.
What should I do?
Make your plugin open source?
Best wishes,
Hamish
