Knowing you're in the middle of readying 1.5.0, I'm want to see whether this is
a real RubyGems issue or something else.
I use an operating_system.rb and a custom devkit.rb to enhance how "gem install
my_native_gem" and "ruby -r devkit extconf.rb" behaves when building for
Windows using RubyInstaller. As of ruby-core trunk@30653 the
operating_system.rb functionality appears to have stopped working. Things stil
work on "ruby 1.9.2p160 (2011-01-16 revision 30579) [i386-mingw32]"
I suspect this isn't a RubyGems issue, but an expected ruby-core trunk
stabilization issue. Is the following "failure" (operating_system.rb's
pre_install hook not working so build tools not put on PATH) expected at this
point in the RubyGems refactoring?
=== FAILING CASE ===
# file: C:\ruby19trunk\lib\ruby\1.9.1\rubygems\defaults\operating_system.rb
#
# :DK-BEG: override 'gem install' to enable RubyInstaller DevKit usage
Gem.pre_install do |gem_installer|
unless gem_installer.spec.extensions.empty?
unless ENV['PATH'].include?('C:\\DevKit\\mingw\\bin') then
Gem.ui.say 'Temporarily enhancing PATH to include DevKit...' if
Gem.configuration.verbose
ENV['PATH'] = 'C:\\DevKit\\bin;C:\\DevKit\\mingw\\bin;' + ENV['PATH']
end
ENV['RI_DEVKIT'] = 'C:\\DevKit'
ENV['CC'] = 'gcc'
ENV['CPP'] = 'cpp'
ENV['CXX'] = 'g++'
end
end
# :DK-END:

=== WORKING CASE ===
While I'm tracking down other rdiscount 1.6.8 functionality issues, with the
following devkit.rb library I can manually get this build to work:
# file: C:\ruby19trunk\lib\ruby\site_ruby\devkit.rb
#
# enable RubyInstaller DevKit usage as a vendorable helper library
unless ENV['PATH'].include?('C:\\DevKit\\mingw\\bin') then
puts 'Temporarily enhancing PATH to include DevKit...'
ENV['PATH'] = 'C:\\DevKit\\bin;C:\\DevKit\\mingw\\bin;' + ENV['PATH']
end
ENV['RI_DEVKIT'] = 'C:\\DevKit'
ENV['CC'] = 'gcc'
ENV['CPP'] = 'cpp'
