S.O. is amazing but not magic. Patience. :P > Since my GCC installation lives in > "E:\programming\c\libraries\gsl-1.15.tar\gsl-1.15", I changed the directive to > > //-------------------------------------------------------------------------------------- > #include <gsl-1.15/multifit/gsl_multifit.h> > //-------------------------------------------------------------------------------------- This sounds like you are not running 'make install' before trying to compile and link against GSL. Instead, the sounds like you are simply running 'make' and then trying to compile and link against the built sources. Is that the case? I ask because I expect installed headers to be in locations like <gsl/gsl_multifit.h>. - Rhys
