Brian is right. It's all very well putting "--with-mpfr" into the configure script, the trick is actually doing something in response! That requires working with the mpfr_t type, not regular C doubles. Every piece of arithmetic has to be re-written; you can't use the ordinary C math operators with mpfr_t, nor any ordinary C math functions. -- Allin Cottrell Department of Economics Wake Forest University _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
