QtWebEngine Haiku patchset

0000-README.md

These patches are for qtwebengine-everywhere-src-5.12.3.tar.xz, SHA256: 3ff3bac12d75aa0f3fd993bb7077fe411f7b0e6a3993af6f8b039d48e3dc4317

Linking stage for QtWebEngineCore requires 10+GB of RAM :) (debug build)

Additional stuff needed:

Fixed libxslt.pc (non-packaged/develop/lib/pkgconfig) - qmake checks if directories in .pc files exist and will fail with some libs if libxslt was built with libxml2-2.6.2 and libxml2 was later updated to let's say libxml2-2.9.9, libxslt.pc will contain -L with non-existent directory (because it was not rebuilt with newer libxml2) Custom .pc file fixes this.

Create build directory and build-qtwebengine.sh inside of it:

qmake "CONFIG+=debug" .. -- \
	-no-webengine-printing-and-pdf \
	-no-webengine-pepper-plugins \
	-no-webengine-spellchecker \
	-no-webengine-webrtc

cd build
./build-qtwebengine.sh
make
make examples

Copy libraries and cmake files (build/lib) to non-packaged. Maybe adjust CMakes to point to /build/lib.

Build falkon.

mkdir build && cd build
cmake .. -DECM_DIR=/boot/system/data/cmake/Modules/ECM/cmake -DQt5WebEngine_DIR=/boot/home/config/non-packaged/lib/cmake/Qt5WebEngine -DQt5WebEngineWidgets_DIR=/boot/home/config/non-packaged/lib/cmake/Qt5WebEngineWidgets/ -DQt5WebChannel_DIR=/boot/system/lib/cmake/Qt5WebChannel -DQt5Positioning_DIR=/boot/system/lib/cmake/Qt5Positioning -DDISABLE_DBUS=1 -DNO_X11=1

• qtwebengine_resources.pak
• qtwebengine_locales

to /build/bin.

Run in /build/bin:

LIBRARY_PATH=<qtwebengine-path>/build/lib:.:$LIBRARY_PATH QTWEBENGINEPROCESS_PATH=<qtwebengine-path>/build/libexec/QtWebEngineProcess" falkon

stderr:

[168503:-752511648:0707/034611.273591:ERROR:broker_posix.cc(40)] Recvmsg error: Socket operation on non-socket (-2147454932)

That's probably why the window is empty (it can't communicate with the process).

It's also possible that I have botched something in the renderer. ¯\_(ツ)_/¯

Nice work!

I adapted your patches to the latest version of QtWebEngine 5.15.0, rewrote the functions of getting the stack to use pthread_getattr_np and many other fixes. I’ll post a patch soon.

Any news on bringing QTWebEngine to Haiku?

Sorry, but no. I adapt patch to QtWebEngine 5.15, but the render crashes a second after starting.

Looked like the video showed some promising progress, I still hope it would work one day. Anyhow good luck!
