Hi,

There is user made assembly function in my program, which I was using in different ".c" files and it was working fine .

But when I used it in a ".cpp" file I got a link error L1822 : Symbol functionname__FUc in file is undefined.

I tried everything to resolve it.

Included ansixbf.lib file.

Included the extern prototype of the function but its not working .

So if anybody knows about this link error plz help.

Thanks.

Hello

Did you specify in the prototype of the assembly that it should use the C name mangling?

In order to do that the prototype should be enclosed between

#ifdef __cplusplus
extern "C" {
#endif

and

#ifdef __cplusplus
}
#endif
