I'm on Windows XP and using GNU G95 (2003 standard) with the option
-fno-underscoring and GNU C++ 18.104.22.168.
Because I have no problem to call Fortran from C this can't ba a
conflict with the names. Meanwhile I found out that the problem is not
related to Fortran. Now I have this C main:
extern "C" void qqcprint();
and my C routine is quite the same:
extern void qqcprint()
The module is in the project al well as in the linked modlib qqmodlib.a
But the message I get is always
[Linker error] undefined reference to `qqcprint'. The 'nm' program was
not in the delivery.
