Hello all,
I recently downloaded the GSL but have been having trouble with the
#include options in these files.
Header include commands for GSL invariably take the form of, say,
#include <gsl/gsl_rng.h>
but the header file concerned is usually not actually located in the
gsl/ directory, so the compiler fails to find it. (Note that I *am*
using the -I compiler option to tell it where the gsl/ directory is.)
The result is that even the simple example program given in the GSL
manual, which makes use of the gsl_sf_bessel.h header, won't compile!
The error message produced in that case is: gsl/gsl_sf_bessel.h: No such
file or directory. I get a similar message when, e.g., I try to compile
the ran1.c random number generator, although this also fails to find the
config.h header.
Note that I deliberately *don't* want to just compile to object form the
whole GSL. Rather, I'd like to be able to compile individual modules
as-and-when necessary for different projects. I'd also like a solution
that is independent of the compiler used---gcc is great, but sometimes
other compilers can produce faster number-crunching and that's often
important to me.
... So, how do I solve this "include" problem without rewriting the GSL
code? :-)
Many thanks & best wishes,
-- Joe
