Disclaimers: I am guessing what you have in your makefile,
and I don't know much about g++/libgmp, but I see several
possible problems with your command. The particular problem
that you are asking about seems to be that
a) -lgmp should follow *.C
b) I am not 100% sure that this is what happens, but it is likely
that the loader thinks that -lgmp is the executable you are
trying to create (because of the -o option), and does not
link libgmp at all.
There are other things related to make that I'll skip here
The linkage rule should probably be sth like (assuming GNU make)
prog: $(OBJS)
$(CXX) -o $@ $^ -lgmp
where $(OBJS) will be all your *.o files (you can through in -g and -O
if you feel like it). A version closer to yours, but less clean
(IMHO), will look like
g++ -o prog -g -O *.C -lgmp
If you think I can be of further help, or if it is not entirely clear
why I suggest linking objects separately from compiling sources,
you are welcome to contact me off the list.
