Cross-compile QT (w/ QTWebEngine) for Pi 3: EGLSetBlobFuncANDROID/EGLDeviceEXT not declared

[vpetersson]

Hi guys,

I've taken on the somewhat ambitious project of trying to cross-compile QT for all existing Raspberry Pis for Screenly OSE.

In the last few weeks, I've made good progress, and I've managed to move the entire compilation process into Docker, and script it end-to-end.

In short, I'm able to build QT Base just fine and it picks up hardware acceleration for both Pi 3 and Pi 4 (my initial targets). I'm also able to build QTWebEngine just fine for Pi 4, but on Pi 3 it is choking with the following error:

I'm aware that this error closely resembles the error Enrico Zini descibes here, however his workaround dpkg --purge libraspberrypi-dev (or rather Andreas Gruber's) won't cut it as it will disable hardware acceleration, which I need.

Any pointers would be greatly appreciated.

(Apologies for the StackOverflow cross-post)

hi vpettersson,

i got the same errors and got it working with 3 symlinks:

in sysroot/opt/vc/include/EGL

mv egl.h egl.h-old
mv eglext.h eglext.h-old
mv eglplatform.h eglplatform.h-old

ln -s /home/jw78/raspi/qt-everywhere-src-5.15.2/qtwebengine/src/3rdparty/chromium/third_party/khronos/EGL/eglext.h eglext.h
ln -s /home/jw78/raspi/qt-everywhere-src-5.15.2/qtwebengine/src/3rdparty/chromium/third_party/khronos/EGL/egl.h egl.h
ln -s /home/jw78/raspi/qt-everywhere-src-5.15.2/qtwebengine/src/3rdparty/chromium/third_party/khronos/EGL/eglplatform.h eglplatform.h

of course you must adjust your paths (/home/jw78/raspi/qt-everywhere-src-5.15.2)

there are many egl.h/eglext.h/eglplatform.h to include and because of the include order the comiler fetches first the files in sysroot/opt/vc/include/EGL
probably the better solution is to reorder the "-I" flags for the compiler, but i have no idea how to do this

i did not
dpkg --purge libraspberrypi-dev
