In my project Core libraries are part of C/C++ files, while UI needs to be developed in Objective C,
I am able to access/Call C++ functions from Objective C/.mm files
but reverse no luck so far, i.e. i am not able to call Objective C functions from C++ Files,
when i tried to include Objective C header even system header
#import <foundation/foundation.h>
getting around 1000+ compilation error,
something like this
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:180:0 /Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:180: error: expected unqualified-id before '@' token
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:182:0 /Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:182: error: expected initializer before '*' token
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:183:0 /Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSObjCRuntime.h:183: error: 'NSString' was not declared in this scope

Am i missing some pre-compile flag etc..
can anyone suggest me, the best possible way to call/access objective C class which is inherited from NSObject, without modifying much C++ code, i just need to call one function
Code structure / Order to include header files are
Some system header file
Some Core Class Header file
#import <foundation/foundation.h>
If you have a .cpp file with C++ code that needs to use Objective-C as well, either rename that .cpp file to .mm or pass
-x objective-c++to the compiler.
