I am not sure what you mean by "link". Like in linking a program to a .so/.la file?

In that case, assuming you are using gcc, you just send the -l flag as many times you want:

gcc file.cpp -o program -lmath -lpthread -lsomeotherlibrary

There is a difference between linking static libraries and shared libraries. Here is a sample from a Makefile:

Quote:

INCS=-I/usr/include/GL -I.
LIBS=-lm -lGL -lGLU
AUXLIBS=./libaux.a ./libtk.a

cube:
gcc -c openglbk_0/cube.c $(INCS)
gcc -o cube cube.o $(AUXLIBS) $(LIBS)
@echo "done cube build"

Static lib usually end with .a, shared libs tend to use the .so naming convention. Shared libs are prefixed with '-l', and a libfile name 'libGL' is used as '-lGL' (note: 'lib' is omitted in the usage). Static libs are simply defined by their pathname.
