QtWebEngine/Qt5Build

Building for Raspberry Pi

If you are interested in trying QtWebEngine with WebGL support on RasberryPi3 with the open source Vc4 driver see here.

Building on MacOS

Install build dependencies

QtWebEngine 5.x series require Python 2.7 which is not longer supported, therefore the easy way to obtain it is to use pyenv.

brew install pyenv
pyenv install -l
pyenv install 2.7.18
pyenv global 2.7.18
pyenv init --path
export PATH="/Users/qt/.pyenv/shims:${PATH}"
ulimit -n 1200

Obtain Qt5 sources code

mkdir qt5
cd qt5

git clone git://code.qt.io/qt/qtbase.git
git clone git://code.qt.io/qt/qtdeclarative.git
git clone git://code.qt.io/qt/qtwebengine.git

cd qtwebenigne
git submodule update
cd ..

Configure compile for x86_64 or for arm64 (Big Sur)

mkdir -p build/qtbase
cd build/qtbase
../../qtbase/configure -opensource -confirm-license -verbose -prefix /Users/qt/install/5.15.release -release -force-debug-info -separate-debug-info -nomake tests -nomake examples -no-pch

Configure to cross-compile build (x86_64 -> arm64)

mkdir -p build/qtbase
