Description of problem: When I install rubygem-ffi-1.0.9-8.el6.x86_64.rpm from EPEL, gem list does not show the gem and attempt to install gem which requires ffi fails: # gem install --local /root/rpmbuild/SOURCES/gssapi-1.1.2.gem ERROR: While executing gem ... (Gem::DependencyError) Unable to resolve dependencies: gssapi requires ffi (>= 1.0.1) When I install the package from Katello koji http://koji.katello.org/koji/buildinfo?buildID=2072, things work. Version-Release number of selected component (if applicable): rubygem-ffi-1.0.9-8.el6.x86_64 How reproducible: Deterministic. Steps to Reproduce: 1. Install rubygem-ffi from EPEL. 2. Run gem list Actual results: # gem list *** LOCAL GEMS *** archive-tar-minitar (0.5.2) commander (4.0.3) gssapi (1.1.2) highline (1.6.16) httpclient (2.3.2) net-ssh (2.5.2) open4 (1.3.0) parseconfig (0.5.2) rhc (1.10.1) test-unit (2.2.0) Expected results: # gem list *** LOCAL GEMS *** archive-tar-minitar (0.5.2) commander (4.0.3) ffi (1.0.9) gssapi (1.1.2) highline (1.6.16) httpclient (2.3.2) net-ssh (2.5.2) open4 (1.3.0) parseconfig (0.5.2) rhc (1.10.1) test-unit (2.2.0) Additional info: When I unpack the two rpms and diff them, the difference is # diff -ru rubygem-ffi-1.0.9-5.el6.x86_64 rubygem-ffi-1.0.9-8.el6.x86_64 Only in rubygem-ffi-1.0.9-5.el6.x86_64/usr: lib Only in rubygem-ffi-1.0.9-8.el6.x86_64/usr/lib64: gems Only in rubygem-ffi-1.0.9-5.el6.x86_64/usr/lib64: ruby Only in rubygem-ffi-1.0.9-8.el6.x86_64/usr: share And since gem env shows # gem env RubyGems Environment: - RUBYGEMS VERSION: 1.8.16 - RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux] - INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.8 - RUBY EXECUTABLE: /usr/bin/ruby - EXECUTABLE DIRECTORY: /usr/bin - RUBYGEMS PLATFORMS: - ruby - x86_64-linux - GEM PATHS: - /usr/lib/ruby/gems/1.8 - /root/.gem/ruby/1.8 - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :benchmark => false - :backtrace => false - :bulk_threshold => 1000 - REMOTE SOURCES: - http://rubygems.org/ I assume rubygem-ffi-1.0.9-8.el6.x86_64's lack of the /usr/lib directory is the cause of the problem.
Created attachment 878984 [details] dist-git patch Attached is a patch against the el6 git branch that fixes the build issues with placement of the library and gemspec. Scratch build: http://koji.fedoraproject.org/koji/taskinfo?taskID=6675314 (works for me)
Dominic, there is possible to use the Fedora approach, i.e. to require rubygems-devel with all the macros. The only difference between should be the ruby(abi).

The only difference between should be > the ruby(abi). Thanks, I forgot rubygems-devel is now available in EL6. It seems that neither ruby_sitearch or gem_extdir* are defined though, so unless I'm missing something, I'll still need to define and use ruby_sitearch. Attached a new patch which removes lots of %globals and relies on rubygems-devel.
You don't need to move the extension anywhere, since it is already installed into platform specific directory => You don't need gem_extdir nor ruby_sitearch.
The .so gets installed into this path inside an x86_64 buildroot: /builddir/build/BUILDROOT/rubygem-ffi-1.0.9-9.el6.x86_64/usr/lib/ruby/gems/1.8/gems/ffi-1.0.9/lib/ffi_c.so Is that acceptable? I thought it'd have to be under /usr/lib64 at least, hence the mv to /usr/lib64/ruby/site_ruby/1.8/x86_64-linux. If there's a reference (native) rubygem I could base this on, that'd be useful, as I'm looking at rubygem-nokogiri at the moment. Or if you have the time to fix it yourself, that'd be great too. Thanks.
Hm, interesting. I thought that the gems were installed into platform specific directories, but apparently, I was wrong. Then the sitearch dir is the right one. Sorry for confusion.
