rb-gsl's Issues

Fails to build on Ruby 2.1

I don't have a ton of time to look into this (sorry!) and am not even sure where the canonical version of this gem lives (yours is the most accessible/maintained), but…

With Ruby 2.1 and a brew-installed gsl 1.15, I get these errors (and many warnings, but ignoring those) installing the gem:

linalg.c:74:28: error: read-only variable is not assignable
    RBASIC(omatrix)->klass = cgsl_matrix_LU;
    ~~~~~~~~~~~~~~~~~~~~~~ ^
linalg.c:695:28: error: read-only variable is not assignable
    RBASIC(mdecomp)->klass = cgsl_matrix_QR;

    RBASIC(vA)->klass = cgsl_matrix_PTLQ;
    ~~~~~~~~~~~~~~~~~ ^
7 errors generated.
make: *** [linalg.o] Error 1

AFAIK, Ruby 2.1 no longer allows assignment to klass in this manner (it's now declared as const). brianmario/escape_utils#48 appears to solve a similar problem in that codebase, so maybe the same approach could work here. I'd dig deeper into this, but I really just need a normal variable so I'll write my own Box-Muller in Ruby until the gsl bindings support Ruby 2.1.

Make sure the command "gsl-config" is in search path.

when I install ,it get the error "Check GSL>=0.9.4 is installed, and the command 'gsl-config' is in search path.(RuntimeError)" when I do "ruby setup.rb config"

How can I do with the first support "Make sure the command "gsl-config" is in search path." in Windows..

Incompatible type for «gsl_vector_complex_equal» 

compiling vector_complex.c
vector_complex.c:1989:12: error: incompatible type for «gsl_vector_complex_equal»

Got this with gsl 1.15-2, Linux x86-64

inconsistency between GSL::Rand#sample and GSL::Rand#choose

I'm trying to get either a sample of a rounded Vector (GSL::Vector#round) and the choose and sample are behaving differently.

how to test it:

r = GSL::Rng.alloc(GSL::Rng::MT19937,rand(10000))
g = GSL::Vector.alloc([1,2,3,4,5,6,7,8,9,10])
r.sample(g,2) # OK
r.sample(g.round,2) #OK
r.choose(g,2) #OK
r.choose(g.round,2) #TypeError: wrong argument type GSL::Vector::Int (GSL::Vector expected)

Release a new version

The version available on rubygems does not work with gsl 1.15, which makes versioning slightly annoying when I update my packages. Can you release a new version?
