Subject: Mixed Programming

Hi,

    I've been trying to do some mixed C-Fortran programming using
f2c.  All the code fragments compile; moreover, test programs based
entirely on either language work properly.  However when I try to
link the real application I run into trouble, specifically: I first
passed all the fortran sources through f2c, compile with gcc, and
save the output in a library called libFOBJS.a.  I then link the
objects created from the C sources (COBJS) and try to link everything
as follows:

        gcc -m486 -O2 COBJS -lFOBJS -lF77 -lI77 -lm -lc

I get the following output:

fmt.o: Undefined symbol _sig_die referenced from text segment
err.o: Undefined symbol _sig_die referenced from text segment
wrtfmt.o: Undefined symbol _sig_die referenced from text segment
wrtfmt.o: Undefined symbol _sig_die referenced from text segment

These symbols are not used in any of my sources.

Any ideas as to what is wrong?


Thanks in advance,


David Ronis
