.m to .mm causes missing function pointers

Hello,

I have added some ObjC sources ( using Cocoa frameworks ) to an iTunes Visual plugin. Everything worked great until I decided to convert the .m ( ObjC ) source into a .mm ( ObjC++ ) source. Now my ObjC functions for that source file can no longer be linked. They are missing. Just by renaming the source suffix to .mm. I do need the C++ for data structures to pass between my C++ and ObjC sources. Has anyone experienced this? Any better methods to pass data structures between C++ and ObjC? I have read the list and using a void reference pointer seems to be viable and even desired.?

thanks!
