Hi,

I am struggling to make numo-linalg (0.1.5) work in windows 10. I am using it successfully on macos. It is amazing BTW :-)

Notes:

  • I am using Msys2
  • I have installed numo-narray
  • I have installed openblas using pacman
  • I have also tried to compile it from source. Same results
  • I have installed lapack using pacman

libopenblas.a and liblapacke.a are both in C:\msys64\mingw64\lib so I install the gem with

gem install numo-linalg -- --with-openblas-dir=C:\msys64\mingw64\lib --with-lapack-lib=C:\msys64\mingw64\lib

The problem is that when I try default, level 1, 2 or 3, for example

require "numo/linalg/linalg"
Numo::Linalg::Loader.load_openblas "C:\\msys64\\mingw64\\lib"

I always get

RuntimeError: cannot find OpenBLAS library
from C:/Apps/rubies/Ruby22-x64/lib/ruby/gems/2.2.0/gems/numo-linalg-0.1.5/lib/numo/linalg/loader.rb:90:in `load_openblas' 

Any idea?
Thanks
