Which library?  Is that the libf2c library, or some library that you
need to build using f2c?

Please post a complete report.  It doesn't help a bit to see all those
"whatever"s here and there instead of the commands exactly as you
typed them and as the Makefile issued them, and the precise error
messages as printed by the linker.

Generally, it's a bad idea to invoke ld directly rather than via gcc,
because gcc passes some DJGPP-specific arguments to ld, without which
it would generally not work.

Again, please post a complete script of the command and the error
messages.

Are you sure that makefile was supposed to work with DJGPP?
