Dear Michele,
It looks to me like you are linking with libgsl, but not with libgslcblas. You need both to resolve some gsl functions. This is usually handled by the "pkg-config" mechanism - on a linux system you would add `pkg-config gsl --libs` to your linking line, or `gsl-config --libs`. To show you what those outputs look like on my system: ~ $ pkg-config gsl --libs -lgsl -lgslcblas -lm Maybe you can add those three link instructions (-lgsl -lgslcblas -lm) directly in your own build system, and then your final executable should link.
