The new little-endian 64-bit PowerPC platform (powerpc64le-linux) is not currently supported by Xulrunner. I tried the same patch being used for Firefox and it works fine for Xulrunner: http://pkgs.fedoraproject.org/cgit/firefox.git/tree/mozilla-ppc64le.patch Could we please add this patch to Xulrunner on Rawhide? You can apply the patch only on ppc64le to avoid breaking other arches.
Please also consider the following change to the spec file: @@ -351,7 +355,7 @@ export LIBDIR='%{_libdir}' MOZ_SMP_FLAGS=-j1 # On x86 architectures, Mozilla can build up to 4 jobs at once in parallel, # however builds tend to fail on other arches when building in parallel. -%ifarch %{ix86} x86_64 ppc ppc64 +%ifarch %{ix86} x86_64 ppc ppc64 ppc64le [ -z "$RPM_BUILD_NCPUS" ] && \ RPM_BUILD_NCPUS="`/usr/bin/getconf _NPROCESSORS_ONLN`" [ "$RPM_BUILD_NCPUS" -ge 2 ] && MOZ_SMP_FLAGS=-j2
Done.
