- Notes about QT WebEngine by Sharkcz
- patches mentioned here can be used for building QT WebEngine (5.11.2 from http://code.qt.io/qt/qtwebengine.git), chromium 69-based
- had to set "use_jumbo_build = false" to workaround a build issue in V8, somehow it converted mul into mulld and div into divd, leading to errors like " kExprF32Mulld not defined"
- have problems building ffmpeg, so the final link failed
- seems the steps for ffmpeg are (because generate_gn reads the results of a build, needs clang in the default config => modified to use gcc, clang causes issues with missing symbols
- build_ffmpeg.py linux ppc64
- generate_gn.py
- copy_config.sh
- seems the steps for ffmpeg are (because generate_gn reads the results of a build, needs clang in the default config => modified to use gcc, clang causes issues with missing symbols
- https://wiki.raptorcs.com/wiki/File:Qtwebengine.patch - for WebEngine itself
- https://wiki.raptorcs.com/wiki/File:Webengine-chromium.patch - for the bundled Chromium (**Note:** this contains an outdated version of the 0005-sandbox-linux-seccomp-bpf-Add-ppc64-syscall-stub patch above which does not work -- you must use the updated one dated 21-Sep from above or you will get runtime linker failures)
- rename third_party/ffmpeg/ffmpeg_generated.gni.ppc64 to ffmpeg_generated.gni - this is a preparation for packaging work, ideally we would need a complete ffmpeg_generated.gni regenerated for all arches
- PushAllRegisters() needs a real implementation
- how to use
- apply the patchsets
- qmake-qt5
- make
- wait a while and then enjoy :-)
- https://src.fedoraproject.org/fork/sharkcz/rpms/qt5-qtwebengine/commits/ppc is my work in progress on the Fedora qt5-qtwebengine package
- https://koji.fedoraproject.org/koji/taskinfo?taskID=29540352 is temporary location for the result
