The FAQ lists which functions are in which headers and which libraries. In
summary:

For math functions, include MATH.H and link with -lm
For random numbers, include RANDOM.H
For PC specific functions and CONIO.H functions link with -lpc
For graphics functions include GRAPHICS.H and link with -lgr
For C++ classes loink with -lgpp

Note that thew order of the -l entries on the command line is important.
Use:

gcc yoursrc.c othersrc.c custmlib -lm -lgpp -lgr -lpc -o yourobj.cof

(Omit any -l's that you don't need)

As for reading the NM output, try

NM somelib.a >TEMP.TXT

then try

EDIT TEMP.TXT
