Problem with building gem, require path

ruby-talk
1

Hi all,

Windows XP
Ruby 1.8.2

I'm having a bit of trouble building a proper gem for one of the
Win32Utils packages (win32-ipc). This is a C extension. Everything
appears to be fine, except that it installs the shared library (.so)
under "lib", instead of "lib/win32". I've set the Gem#required_paths,
so I'm not sure what I'm doing wrong.

Here is the spec:

require "rubygems"

spec = Gem::Specification.new do |gem|
  gem.name = "win32-ipc"
  gem.version = "0.4.1"
  gem.author = "Daniel J. Berger"
  gem.email = "djberg96@gmail.com"
  gem.homepage = "http://www.rubyforge.org/projects/win32utils"
  gem.platform = Gem::Platform::WIN32
  gem.summary = "A base class for Win32 synchronization objects."
  gem.require_paths << "lib/win32"
  gem.test_file = "test/tc_ipc.rb"
  gem.has_rdoc = true
  gem.extra_rdoc_files = ["CHANGES","README"]
  gem.extensions = ["extconf.rb"]
  gem.rubyforge_project = "win32utils"

  files = Dir["doc/*"] + Dir["examples/*"] + Dir["lib/win32/*"]
  files += Dir["test/*"] + Dir["[A-Z]*"]
  files.delete_if{ |item| item.include?("CVS") }
  gem.files = files
end

if $0 == __FILE__
  Gem.manage_gems
  Gem::Builder.new(spec).build
end

The result is ipc.so installed under
c:/ruby/lib/ruby/gems/1.8/gems/win32-ipc-0.4.1-mswin32/lib instead of
the desired
c:/ruby/lib/ruby/gems/1.8/gems/win32-ipc-0.4.1-mswin32/lib/win32.

Any ideas? I've tried a few things for 'required_libs' without
success.

Regards,

Dan

gem.require_paths << "lib/win32"

Hello,

i found that rubygems copies the libraries in the first require_path,
regardless which path stands in the mkmf create_makefile command. Thats
because installer.rb of rubygems overrides the RUBYARCHDIR and RUBYLIBDIR
variables of the resulting Makefile not considering the target_prefix.
I think its meant to require all files with the autorequire, so the actual
location of the library doesn't matter.
Try gem.require_paths = ['lib/win32','.'] or something to make sure your
desired path is in front or nevermind at all.
I mentioned the use of target_prefix in the Makefile on
Rubygems-developers-mailinglist, but nobody seems to notice.
