Issue #8400 has been updated by jonforums (Jon Forums). @usa, nice...just scanning r40693 :) :) Looks like NET_LUID redef when using mingw-w64 headers is cause of this fail http://ci.rubyinstaller.org/view/Ruby%20Trunk/job/ruby-trunk-x86-build/1514/console Mingw-w64 headers do this L14: http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/tags/v2.0.6/mingw-w64-headers/include/iptypes.h?revision=5856&view=markup L87: http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/tags/v2.0.6/mingw-w64-headers/include/ifdef.h?revision=5856&view=markup Haven't looked at mingw.org or msvc headers to see if simple #ifdef for mingw-w64 would be a potential fix. ---------------------------------------- Bug #8400: skip `Rinda::TestRingFinger` tests on platforms not implementing `getifaddrs()` https://bugs.ruby-lang.org/issues/8400#change-39310 Author: jonforums (Jon Forums) Status: Open Priority: Normal Assignee: Category: core Target version: current: 2.1.0 ruby -v: ruby -v: ruby 2.1.0dev (2013-05-12 trunk 40676) [i386-mingw32] Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN The 32 and 64bit trunk builds at ci.rubyinstaller.org are failing `make test-all` 32bit => http://ci.rubyinstaller.org/view/Ruby%20Trunk/job/ruby-trunk-x86-test-all/1333/console 64bit => http://ci.rubyinstaller.org/view/Ruby%20Trunk/job/ruby-trunk-x64-test-all/1218/console as is my Win7 32bit system because non applicable tests are being allowed to fail with `NotImplementedError` rather than being skipped: [ 1948/13374] Rinda::TestRingFinger#test_make_socket_ipv6_multicast = 0.00 s 7) Error: Rinda::TestRingFinger#test_make_socket_ipv6_multicast: NotImplementedError: getifaddrs() function is unimplemented on this machine c:/Users/Jon/Documents/RubyDev/ruby-git/test/rinda/test_rinda.rb:535:in `getifaddrs' c:/Users/Jon/Documents/RubyDev/ruby-git/test/rinda/test_rinda.rb:535:in `prepare_ipv6' c:/Users/Jon/Documents/RubyDev/ruby-git/test/rinda/test_rinda.rb:665:in `test_make_socket_ipv6_multicast' [ 1949/13374] Rinda::TestRingFinger#test_make_socket_ipv6_multicast_hops = 0.00 s 8) Error: Rinda::TestRingFinger#test_make_socket_ipv6_multicast_hops: NotImplementedError: getifaddrs() function is unimplemented on this machine c:/Users/Jon/Documents/RubyDev/ruby-git/test/rinda/test_rinda.rb:535:in `getifaddrs' c:/Users/Jon/Documents/RubyDev/ruby-git/test/rinda/test_rinda.rb:535:in `prepare_ipv6' c:/Users/Jon/Documents/RubyDev/ruby-git/test/rinda/test_rinda.rb:679:in `test_make_socket_ipv6_multicast_hops' Also, after you've made a commit, I ask that you swing by http://ci.rubyinstaller.org/ to double-check that your commit didn't break the relevant mingw-based Windows build.
