The point is that if you use g++ -c then you are compiling the code to
object form -- not linking it together to form an executable.  The -l...
commands tell the compiler what libraries your program needs to link to
-- and hence if you are using the -c option they are superfluous.  So,
the compiler, being nice and helpful, tells you that.

You only need to use -lgsl -lgslcblas -lm when you are calling g++ to
link together your object files into an executable.
