Subject: | using gsl library.... |
This is newbii !!! We are trying to use the ocmlgsl library. we are trying to call the ugaussian_P function belonging to Gsl_cdf. This works: open Gsl_fun;; let _ = Gsl_error.init () ; Gsl_rng.env_setup () let rng = Gsl_rng.make (Gsl_rng.default ()) let sigma = 3. let _ = Printf.printf "# gaussian with sigma=%g\n" sigma ; for i=1 to 10 do let x = Gsl_randist.gaussian rng 3. in Printf.printf "%+.7f\n" x done This does not compile: let _ = Gsl_error.init () ; Gsl_rng.env_setup () let rng = Gsl_rng.make (Gsl_rng.default ()) let sigma = 3. let _ = Printf.printf "# gaussian with sigma=%g\n" sigma ; for i=1 to 10 do let x = Gsl_cdf.ugaussian_P 3. in Printf.printf "%+.7f\n" x done C:\ocaml\gsl\ocamlgsl-0.4.0\examples>ocamlopt -cclib gsl.lib -I .. bigarray.cmxa ..\gsl.cmxa bs.ml File "bs.ml", line 23, characters 12-31: Unbound value Gsl_cdf.ugaussian_P Do you have any ideas what I do wrong? I am using my own Windows 1.6 build of GSL that I build yesterday. Regards Lars Schouw BTW. I asked this on the ocaml_beginners mailing list and they told me this is to Windows specific. BTW2: From the ocaml_beginner mailing list It works on Debian if you do /usr/lib# ln -s libgsl.so.0 libgsl.so /usr/lib# ln -s libgslcblas.so.0 libgslcblas.so /usr/lib# ldconfig > Then I compiled your second example with: > > $ ocamlopt -cclib -lgsl -I +gsl gsl.cmxa test.ml -o test and ran it with: > > > > $ ./test > > # gaussian with sigma=3 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 > > +0.9986501 BTW3: If I try this I get an unbound module error C:\ocaml\gsl\ocamlgsl-0.4.0\examples>ocamlopt -cclib -lgsl -I +gsl > gsl.cmxa bs.ml -i bs > File "bs.ml", line 2, characters 0-12: > Unbound module Gsl_fun __________________________________ Yahoo!
