I think you may find that with clang absent and not --disable-skia, Skia is not disabled but as the build documentation I referenced earlier says, it falls back to unoptimized paths. If you were to force --disable-skia then I would guess it falls back to using Cairo as it did prior to libreoffice 7. The clang test is looking for "FMA intrinsics" which would speed up fused-multiply-add in the clang-present case. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
