Re: to compile a simple program with gsl

[Achim Gaedke <achim at zpr dot uni-koeln dot de>]

achim@Sparcy02> gcc -c -I/zpr/gnu/include/gsl demo.c

This caueses errors, just because the gsl headers themself use
include-paths like gsl/gsl_math.h, that can't be found.

Please use #include <gsl/gsl_*.h> ,too.

The command 

achim@Sparcy02> gsl-config --cflags
-I/zpr/gnu/include

gives you the flags for compiling gsl-programs:

achim@Sparcy02> gcc -c -I/zpr/gnu/include demo.c

results in demo.o

The same procedure for linking:

achim@Sparcy02> gsl-config --libs
-L/zpr/gnu/lib -lgsl -lgslcblas -lm
achim@Sparcy02> gcc -o demo demo.o -L/zpr/gnu/lib -lgsl -lgslcblas -lm

achim@Sparcy02> ./demo 
 6 3 6 3 4 7 4 6 4 3

I think, this is the full truth.
