Linking c and fortran code

[chris at frostnet dot net]

I'm trying to build an application written in C and Fortran but am having
trouble linking the fortran and c object files.

I've compiled the c code with gcc under cygwin, and the fortran code with
microsoft's fortran compiler (there is a large amount of fortran 90 and 95
code which g77 doesn't grok). When linking the resultant object files, ld
can't find the required symbols for a few std fortran calls, a lot of Xt and
standard C calls (eg printf or strlen), and none of the c code seems to be
able to resolve symbols provided by the fortran code.

If I add an extra underscore to the required symbol names for at least
standard fortran calls to the object files for the fortran code, they
sometimes will resolve (so __foo instead of _foo).

I'm linking in the Mrm, Xm, Xt, Xaw, X11, SM, ICE, and math libraries (in
that order).

Should it be possible to link code like this? Is there anything I could
read to try to figure out what else I need to be doing? Or any suggestions
on what I've left out?

Sorry that this is a bit off topic; I asked the general cygwin group and
didn't get any responses.

a big thanks in advance!
