Hello all,
Since the program I'm trying to modify (replace all the glContexts of) is
written in Objective-C, I need to be able to use the equalizer classes from
within a Cocoa Framework. I thought I would try to compile eqHello.cpp as
eqHello.mm since in Objective-C++ you can mix & match most syntax.
So I made a new XCode project and got all the libraries linked in and such,
and compiling the eqHello file as a .cpp compiles and runs (although it
crashes). Compiling it as a .mm file fails with the following errors:

I feel like I'm going about it the completely wrong way, except the errors
(things like const void* and the BOOL) look like namespace errors.
help?
