==Building for Raspberry Pi==

If you are interested in trying QtWebEngine with WebGL support on RasberryPi3 with the open source Vc4 driver see [[RaspberryPiWithWebEngine|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 <big>pyenv</big>.

<syntaxhighlight>
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
</syntaxhighlight>

===Obtain Qt5 sources code===

<syntaxhighlight>
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 init
git submodule update
cd ..
</syntaxhighlight>

===Configure compile for x86_64 or for arm64 (Big Sur)===

<syntaxhighlight>
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
</syntaxhighlight>

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

<syntaxhighlight>
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 -device-option QMAKE_APPLE_DEVICE_ARCHS="arm64"
</syntaxhighlight>

===Configure for unviersal build (x86_64, arm64)===

<syntaxhighlight>
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 QMAKE_APPLE_DEVICE_ARCHS="x86_64 arm64"
