   I'm trying to compile fortran code converted to C via f2c.  I'm getting many
   undefined references, most (if not all) of which are generated by f2c.  I'm
   including all the libraries (i.e. -lgpp -lgpl -lm -lpc) that are mentioned
   in the FAQ.  I also used nm to search for these in all the libraries.

   I'm hoping that someone recognizes these and tells me that I should be doing
   such and such.  Some of the undefined references are:

   do_fio e_wsfe s_wsfe i_len s_copy

   and many more.

   One other thing.  Does djgpp support double complex variables.  I'm also
   getting an undefined reference to zsqrt and nm doesn't report it being in
   libm.a Do I have to write one myself?

   Thanks, Skip Egley

You need to link in the libraries supplied with f2c, namely:

libF77.a  and  libI77.a

add '-lF77 -lI77' to your link line and a '-L' option pointing to the directory
containing the f2c libraries.
