The -ffast-math option is not recommended for use with GSL. If you build the library with that option the "make check" test suite will fail. -- regards, Brian Gough Network Theory Ltd, Commercial support for GSL --- http://www.network-theory.co.uk/gsl/ _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
