Installed Fedora5. Installed Ruby 1.8.4. Installed rubygems. Installed rails. Created test app to verify that ruby and rails were working. When I attempted to install mongrel via: sudo gem install mongrel I get this error: Install required dependency daemons? [Yn] y Install required dependency gem\_plugin? [Yn] y Building native extensions. This could take a while… can’t find header files for ruby. ERROR: While executing gem … (RuntimeError) ERROR: Failed to build gem native extension. Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/mongrel- 0.3.11 for inspection. ruby extconf.rb install mongrel\n How should I resolve this? -Larry – Best Regards, -Larry “Work, work, work…there is no satisfactory alternative.” — E.Taft Benson ---

Thanks, ruby-devel intalled. But mongrel couldn’t find rdoc. It runs, just no docs. Here is the error message. I thought rdoc was include in ruby. Anyways, here is the error message. /usr/lib/site\_ruby/1.8/rubygems/custom\_require.rb:21:in `require__': no such file to load -- rdoc/rdoc (LoadError) from /usr/lib/site_ruby/1.8/rubygems/custom_require.rb:21:in `require’ from /usr/lib/site\_ruby/1.8/rubygems/doc\_manager.rb:43:in `generate_rdoc' from /usr/lib/site_ruby/1.8/rubygems/gem_commands.rb:215:in `execute’ from /usr/lib/site\_ruby/1.8/rubygems/gem\_commands.rb:214:in `execute' from /usr/lib/site_ruby/1.8/rubygems/gem_commands.rb:153:in `execute’ from /usr/lib/site\_ruby/1.8/rubygems/command.rb:49:in `invoke' from /usr/lib/site_ruby/1.8/rubygems/cmd_manager.rb:94:in `process\_args’ from /usr/lib/site\_ruby/1.8/rubygems/cmd\_manager.rb:67:in `run' from /usr/lib/site_ruby/1.8/rubygems/gem_runner.rb:13:in `run’ from /usr/bin/gem:17 On 3/23/06, Łukasz Piestrzeniewicz [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > > Installed rails. > > can’t find header files for ruby. > > [http://lists.rubyonrails.org/mailman/listinfo/rails](http://lists.rubyonrails.org/mailman/listinfo/rails) – Best Regards, -Larry “Work, work, work…there is no satisfactory alternative.” — E.Taft Benson ---

Would people find it helpful to have a set of “platform specific blockers/solutions” document for things like this? Debian has similar niggling little things like this. Thoughts on what would be required? Zed A. Shaw > **[Zed A. shaw](https://zedshaw.com/)** > > Personal essays and writings by Zed A. Shaw. ---

I’m not sure what you mean by ‘blockers/solutions’, but I would be nice to have an easy to find installation guide that would cover specifics on various platforms. Is this something that should be put into the wiki? -Larry On 3/23/06, Zed S.
