ld: symbol(s) not found for architecture x86_64

[rafter]

Hello,
This is my first question in this forum so if I'm posting in the wrong place I apologize. I'm an astronomer trying to work with a piece of software called vpguess. This software requires a program called pgplot (along with cpgplot) and a few libraries (cfitsio). After installing both the gcc and gfortran compilers (64 bit I think??) and using 'make' from the command line I install pgplot and cpgplot. When I update the Makefile for vpguess and try to 'make' I get the following error:


Undefined symbols for architecture x86_64:
"_cpgask", referenced from:
_vpgedit in vpgedit.o
_vpgopen in vpgopen.o
#a long list of the "referenced from" fortran programs, then finally at the end the error
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make: *** [vpguess] Error 1

I believe this has something to do with the 32-bit/64-bit compilers but when I updated and recompiled everything I still get the same error messages. Any thoughts ideas?

Thanks in advance for any help,
Stephen

This may mean it's not linked properly.

Okay. So I'm very new to the Mac OS. How do I go about linking the proper libraries or whatever it is I need to do?

You will need to find someone with

gcc and gfortran compiler
