the easiset is to use a makefile.
Put it into the same dir as the source and then type 
"make" instead of "g++" or "gcc"
The make file should have this in it:


GSLLIBS = -L/usr/local/lib -lgsl -lgslcblas
GSLINCS = -I/usr/local/include

# space seperated list of source files in program
SOURCES = source.cpp

# change testProgram.exe to the name you wish your
# executable program to be
xycprogram: $(SOURCES)
        g++ -o $@ $(GSLINCS) $(GSLLIBS) $(SOURCES)
