build qtcharts with OpenGL ES2

DungeonLords · 6 Dec 2020, 14:00

I want to build Qt6 with qtcharts from git. Some modules that I do not need I am skipping.
I have got 3 folders in base folder: qt5 (Sources), build (to configure and build), build_artifacts for build artifacts (always empty I do not know why). I read https://wiki.qt.io/Building_Qt_5_from_Git and install all necessary packages on my Ubuntu 20 on Orange Pi 4.
git clone git://code.qt.io/qt/qt5.git qt5 &&
cd qt5 &&
perl init-repository --module-subset=default,qtcharts,-qtwebengine,-qtwayland,-qtandroidextras,-qtvirtualkeyboard,-qtquick3d
cd ../build

Configure my Qt6:
../qt5/configure -developer-build -opensource -nomake examples -nomake tests -confirm-license -skip webengine -skip qtwayland -skip qtandroidextras -skip qtdoc -skip qtgraphicaleffects -skip qtqa -skip qttranslations -skip qtvirtualkeyboard -skip qtquicktimeline -skip qtquick3d -skip qtrepotools -skip qtdeclarative -skip qttools -skip qtshadertools -skip qtimageformats -skip qtnetworkauth -skip qtquickcontrols2 -skip qtsvg -skip qtwebsockets -skip qt5compat -opengl es2 -prefix ../build_artifacts -v

Orange Pi 4 do no support Desktop OpenGL, but OpenGL ES2. I try make -j8 and
error with qtcharts:
QtWidgets/QOpenGLWidget: No such file or directory.

Is it because qtcharts need Desktop OpenGL? Can I change qtcharts to use OpenGL ES2?
