perl-OpenGL-0.6702-4.fc23 fails to build in F23 because tests fail on linking with Mesa OpenGL library: + make test "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t # Failed test 'require OpenGL;' # at t/00_require.t line 3. # Tried to require 'OpenGL'. # Error: Can't load '/builddir/build/BUILD/OpenGL-0.6702/blib/arch/auto/OpenGL/OpenGL.so' for module OpenGL: /builddir/build/BUILD/OpenGL-0.6702/blib/arch/auto/OpenGL/OpenGL.so: undefined symbol: glWindowPos4dMESA at /usr/lib64/perl5/DynaLoader.pm line 193. # at (eval 4) line 2. # Compilation failed in require at (eval 4) line 2. # Looks like you failed 1 test of 1. t/00_require.t ....... Dubious, test returned 1 (wstat 256, 0x100) Failed 1/1 subtests This is caused by upgrading mesa-libGL-devel from 10.6.0-0.devel.5.51e3453 to 10.6.0-0.devel.6.5a55f68.
