Re: Problem mixing C and C++ codes

Altera_Forum · ‎07-27-2004

Hi all,

I am justing using NIOS IDE for one day.

I can compile/link C sources in IDE. I can also compile C++ sources, but linker complained "undedfined main",

since I compile the source with the 'main' function in a C++ way (because the main function needs to access C++ programs.

Any suggestion how to mix C codes with C++ classes?

Regards,

Kwok Wong

Problem solved: define C main function in C++ program

extern "C" {

int main() {

// C++ codes

}

FYI, you can also say:

extern "C" int main() {
    // C++ codes
}

Might be a little easier on the eyes.
