That's from 2002. Use GSL 1.15 from ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz. Secondly, what are the compilation and link lines appearing above the linking error message that you see? For example, when I run 'make' within the siman directory, I see messages beginning like /bin/sh ../libtool --tag=CC --mode=compile gcc ... libtool: compile: gcc ... /bin/sh ../libtool --tag=CC --mode=link gcc ... libtool: link: ar ... What do you see? I suspect that what you see is missing a '-lm' flag which is why you're getting undefined reference errors to math routines like atan and exp. - Rhys
