Question

This error comes only when im working in a C file (not CPP)

I came across a very weird error while working on some opengl sample, I narrowed it down to below code, which produces the same error I’m getting, type not found

#include "stdlib.h"
void Initialize(int, char*[]);

void main()
{
}

void Initialize(int argc, char* argv[])
{
    int i;
    for(i = 10; i>0;i--)
    {
        int j=0;
        j = j+2;
        int GlewInitResult2;
    }
}

I used visual studio 2008, OS: windows xp

cant understand why this is happening? is this a compiler bug?

(btw, it compiles fine if i save the file as a .CPP file)

Answer 1

You have declarations after statements. In newer versions of C (like C99), you can have this but in older versions you cannot. Microsoft’s C compiler is old. In C++ it’s OK, which is why it builds.
