Default Fusion Imagine Material Universal "WARNING: Thumb instruction set is required to build ffmpeg for QtWebEngine" Note: I am not using Webkit - so I skipped the compilation because I got a warning which I could not resolve for RPI zero. Unfortunately, this doesn't solve all deployment problems especially on Windows virtual machines without hardware acceleration. As we cannot depend on an installed OpenGL driver, we need to use the ANGLE backend. Qt5 can use the OpenGL driver or the DirectX Driver by using ANGLE. configure -release -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-圆4/bin/arm-linux-gnueabihf-sysroot ~/raspi/sysroot -opensource -confirm-license -skip qtwebengine -no-icu -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -no-use-gold-linker -v -no-gbm Deploying Qt5 on Windows without Hardware Acceleration. ![]() When I set up the toolchain I used this configuration. However when I start the application locally on the RPi I get: QXcbIntegration: Cannot create platform OpenGL context, neither GLX or EGL are enabled failed to acquire GL context to resolve capabilities, using defaults.Īnd all of the widgets with any transparency do not render correctly, either completely transparent or a white overlay. my transparency elements on widgets are all rendering OK). I DO NOT get any issues, and the 3D graphics render OK (e.g. All is OK when I launch the application from QT Creator or via a remote terminal console, e.g. To solve this, do the following: In the bashrc/zshrc file, add the following: export LIBGLALWAYSINDIRECT0 Or you could just remove export LIBGLALWAYSINDIRECT1 line from your bashrc/zshrc file if you have added it. ![]() ![]() I have a QT Quick application running on a Raspberry Pi Zero (Buster), QT5.12.11 cross compiled on a Ubuntu 20.04 VM using the well published tutorials.
