Calling subroutine in fortran module

[Amit]

I tried calling a subroutine in a fortran module from C ,but couldn't.I
always get the error: undefined reference in the main.o file (main is
in C calling the subroutine).

for calling the subroutine I used the following name:
modulename_MP_subroutinename_(...)
and all possible variant (upper case,lower case).Can anybody help (for
a unix system)

Probably not here. The C language doesn't define the mechanism for
calling Fortran subroutines; it's likely to depend on the OS and on
the C and Fortran compilers. If the documentation for your Fortran
compiler doesn't have the information you need, you might try
comp.unix.programmer.

We must do something. This is something. Therefore, we must do this.

Not here. It's off topic and not remotely portable nor
standardized. Try a newsgroup that deals with your particular
system and compiler(s).

comp.unix.programmer.

Or comp.lang.fortran, who do accept crosslanguage issues (as c.l.c
with its much higher traffic does not) and whose regulars have
experience with such issues on a variety of systems. But it is true
the correct answer frequently depends on your Fortan compiler (and
options) and sometimes your OS and/or C compiler, so specify them.
