[Help-gsl] Problems linking - Undefined symbol

[Stephan Klatt]

Hi,

I'm rather new to the C business, so my question will probably be rather
basic; sorry for that.

I want to use gsl_matrix. So I included <gsl/gsl_matrix.h> in my
program code and wrote
gsl_matrix *m = gsl_matrix_alloc(3,3);
just like in the example program of the manual. Compiling is no problem,
but when I try to link, I get the error message
"Undefined Symbol gsl_matrix_alloc; first referenced in file testing.o"
How can that be? Thanks for any help!

Stephan.
