Hi, All:

I have an Linux object file, for example, foobar.o. Can I know which
version
of gcc build it?

What if it was build with a COBOL compiler, and not gcc at all?

In any case, this is not a language issue, since the language doesn't
define the format of object files. Try asking in
news:comp.os.linux.development.apps or maybe somewhere in
news:gnu.gcc.*.

Hi,

you may need this line in your header file or cpp (up to you)

extern "C"
{
void your_asm_func();
....
....
....
}

I would add above in header file.
If you don't add you will have a problem when you link it.
Why? because c++ compiler mangle name difference from c compiler.

Regards,
