The configure script errors out when checking:
AC_TRY_LINK([#include <gsl/gsl_complex.h>],
[gsl_complex a; GSL_SET_COMPLEX(&a, 1.0, 1.0); gsl_complex_logabs(a);],
HAS_GSL_LIB=yes, HAS_GSL_LIB=no)
This works fine on F25.
I checked gsl, and the package not only hasn't changed recently, it hasn't even been built in rawhide (still f25 version). gcc has also not changed.
The package was building fine Friday, and in fact, still builds successfully on my rawhide box (and another developers box).
Any ideas?
