problem with installing

[weepy]

my install log looks like :

You need to have those libraries installed.

[weepy]

I do. I installed libsnd from source and did a gem install for narray.

in irb

require "narray"
=> true

[fugalh]

The C compiler needs to be able to find narray.h as well, you may need to set CPPFLAGS and LDFLAGS. (It may be easier to install narray from source, which will install it to a standard location unlike a gem install.)

(The sf_open error is a red herring, it actually succeeded in the second stanza.)

[weepy]

ok got it working. I install narray from source. i also had to do a gem install (so it was accesible from my ruby install). I also had to add a require "rubygems" in lib/audio.rb for some reason. Once i'd done this -- i managed to run rake and rake install.

Next up tests.... test_audio.rb passes, but test_sndfile.rb fails everything with "RuntimeError: Invalid test wav"
