after a but of hacking with msys and mingw i think i’ve compiled an easy
install version of the rb-gsl bindings. for those of you who don’t know
these are, the gnu scientific library (gsl) is by far the best
open source algorithms for scientific computing available. you can read
the gsl and ruby bindings to it here
the installer also installs the amazing narray package, which integrates
nicely with the gsl
this is the first thing i’ve compiled using the msys/mingw approach so
100% certain that my approach – which i’ll be writing up on the sciruby
(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
– is the best one.
because of this please consider this pre-release experimental. the
my releasing it now is to uncover any gotchas before writing up the
for others to follow.
here are the steps to install
download this tar ball
unpack using winzip, etc. if using winzip be aware that you need
your options as the defaults will destroy valid tar balls. this is
‘feature’ of winzip.
cd do the directory you just unpacked and run
you should now be able to run something like this from the dos prompt
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
Rational class that i’ve not yet found a resolution too.
i’m in uncharted territory here so any and all comments are welcome.
