Pre compiled gnu scientific library for win one-click-instal


#1

hi all-

after a but of hacking with msys and mingw i think i’ve compiled an easy
to
install version of the rb-gsl bindings. for those of you who don’t know
what
these are, the gnu scientific library (gsl) is by far the best
collection of
open source algorithms for scientific computing available. you can read
about
the gsl and ruby bindings to it here

http://www.gnu.org/software/gsl/manual/html_node/
http://rb-gsl.rubyforge.org/

the installer also installs the amazing narray package, which integrates
nicely with the gsl

http://narray.rubyforge.org/index.html.en

this is the first thing i’ve compiled using the msys/mingw approach so
i’m not
100% certain that my approach – which i’ll be writing up on the sciruby
wiki
(http://sciruby.codeforpeople.com) in a few days and which applies to
compiling any posix package under windows in a way that’s one-click
compatible
– is the best one.

because of this please consider this pre-release experimental. the
purpose of
my releasing it now is to uncover any gotchas before writing up the
process
for others to follow.

here are the steps to install

that’s it.

you should now be able to run something like this from the dos prompt

set RUBYOPT=

c:\ruby\bin\ruby -r gsl -e’ p GSL::Rng.new.uniform ’

which print out a random numder. it’s important to unset the RUBYOPT
environment variable as the gsl and rubygems have a naming conflict with
the
Rational class that i’ve not yet found a resolution too.

i’m in uncharted territory here so any and all comments are welcome.

enjoy.
