gsl-2.1 breaks rb-gsl #24
Description
The latest rb-gsl release does not build against the current gsl 2.1 release. I see:
histogram.c: In function 'rb_gsl_histogram_fit_gaussian':
histogram.c:1222:23: error: 'gsl_multifit_fdfsolver' has no member named 'J'
gsl_multifit_covar(s->J, 0.0, covar);
^
histogram.c: In function 'rb_gsl_histogram_fit_rayleigh':
histogram.c:1356:23: error: 'gsl_multifit_fdfsolver' has no member named 'J'
gsl_multifit_covar(s->J, 0.0, covar);
^
histogram.c: In function 'rb_gsl_histogram_fit_xexponential':
histogram.c:1492:23: error: 'gsl_multifit_fdfsolver' has no member named 'J'
gsl_multifit_covar(s->J, 0.0, covar);
