Hi. If you didn't find the solution yet the best thing is to send a complete program that can be compiled and shows the problem. Without that it's difficult to guess. The test suite exercises all the minimisers on some non-trivial problems so it should work and if it does not it might be a bug. _______________________________________________ Help-gsl mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-gsl
