I have been working in Objective-C for my game. I have a class that is made with OBJC++ so that i can use fstream as well as the cocoa framework. the whole program compiles fine, but when ever I link to my Model header, all of a sudden fstream cannot be found and using namespace std; gives aparse error before namespace. Can ne1 help me out?

    It sounds like the linker is expecting Obj-C and getting Obj-C++.



    No, wait... you're getting a parse error on *LINKING*?? That makes zero sense.

    tell me about it. I think i might have found a way to go without using the C++ section. But that will require changing around a hundred lines or so. And I still wont be sure it works. Maybe I sould change the calling class to an OBJC++ class just to see what happenes. When I get back home I wil try it.

    check the extension of the source file



    eg if you have cpp code in a .c file most linkers

    will barf

    Ah.....



    .c = C

    .cpp/C = C++

    .m = Obj-C

    .M = Obj-C++





    Sure that 'Obj-C++' file doesn't have a .m extension?

    c++ is .cc under unix/linux/solaris etc etc

    .cpp is also commonly used
