Hi Lars, it depends on how exactly you've installed it, but the following works here (on an MSVC build of both ocaml and GSL) $ ocamlopt bigarray.cmxa -I +gsl gsl.cmxa bs.ml -cclib gsl.lib $ ./camlprog.exe # gaussian with sigma=3 +0.9986501 +0.9986501 +0.9986501 +0.9986501 +0.9986501 +0.9986501 +0.9986501 +0.9986501 +0.9986501 +0.9986501 If gsl.cmxa is in ".." you should have: C:\ocaml\gsl\ocamlgsl-0.4.0\examples>ocamlopt -cclib gsl.lib -I .. bigarray.cmxa gsl.cmxa bs.ml James Lars Schouw wrote: >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.
