Hello,
It looks like the test tolerances are too tight for 32 bit - all of
my testing has been on 64 bit systems and I unfortunately don't have
access to a 32 bit system to debug this. Just to verify, did you see
these same failures for version 2.0? That code didn't change at all
between 2.0 and 2.1 but just wanted to make sure.
The first thing I would try is to locate lines 178-179 of
multifit/test_nonlinear.c:
178 const double xtol = pow(GSL_DBL_EPSILON, 0.9);
179 const double gtol = pow(GSL_DBL_EPSILON, 0.9);
and increase these tolerances (set both them to 1.0e-3 as a starting
point). Could you let me know if the test passes with this change? Then
it would simply be a matter of finding a good value to get 32 bit tests
to pass.
