>From older documentation. "The class hierarchies are separate; a C++ class cannot inherit from an Objective-C class, and an Objective-C class cannot inherit from a C++ class." This may or may not help. I use the following inline macro for C++ prototypes in dual purpose headers. #ifdef __cplusplus #define CPP(x) x #else #define CPP(x) #endif That way you can import or include the same header into a .m or .mm source file. --Richard Charles _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
