I have a program written in qt using qtwebengine. When i compile it on linux it works. however when i use the pi cross compiler i get the following message
Project ERROR: Unknown module(s) in QT: webengine webenginewidget
The installation went
i tried to reinstall the qtwebengine using this
/opt/qt5pi/qt-everywhere-src-5.10.1/qtwebengine$ ../../qt5build/qtbase/bin/qmake -r
but i get this

I installed the following dependencies
https://wiki.qt.io/QtWebEngine/How_to_Try
then i tried downloading the source alone of webengine

Prior to reconfiguration, make sure you remove any leftovers from the previous build. V8 snapshot cannot be built. Most likely, the 32-bit host compiler does not work. Please make sure you have 32-bit devel environment installed, or configure webengine with '-no-webengine-v8-snapshot' QtWebEngine will not be built. -
Hi,
@SherifOmran said in compiling qt webengine fail:
xcomposite ........................... no
xcursor .............................. no
xi ................................... no
xrandr ............................... no
xtst ................................. noYou are still missing the corresponding development packages as it seems.

@SherifOmran
your configuration seems good so far. What backend you plan to use? For X11 you have to install the packages (armhf @SGaist mentionedRequired system libraries for qpa-xcb: libdrm ............................... yes xcomposite ........................... no xcursor .............................. no xi ................................... no xrandr ............................... no xtst ................................. noI had the problem (also especially with Qt 5.10.1) that i only was able to cross compile QtWebEngine with the
-no-webengine-v8-snapshotoption. There is also a bugreport regarding this IIRC.Also your first post shows that you tried to build Qt statically?
