Crosscompile QT 5.15.2 for raspberry pi 4 - bullseye problems

[themts]

Hi guys,

did anyone manage to crosscompile QT for bullseye yet?
I want to cross-compile QT 5.15.2 but qt-compiling always fails with some EGL errors.

qt-everywhere-src-5.15.2/qtbase/src/plugins/platforms/eglfs/deviceintegration/eglfs_brcm/qeglfsbrcmintegration.cpp:74:5: Error: »EGL_DISPMANX_WINDOW_T« was not declared in this scope
     EGL_DISPMANX_WINDOW_T *eglWindow = new EGL_DISPMANX_WINDOW_T;
...

my configure params look like that:

/qt-everywhere-src-5.15.2/configure -release -opengl es2  -eglfs -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=/opt/qt5pi2021/tools/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /opt/qt5pi2021/sysroot -prefix /usr/local/qt5.15 -extprefix /opt/qt5pi2021/qt5.15 -opensource -confirm-license -skip qtscript -skip qtwayland -skip qtwebengine -nomake tests -make libs -pkg-config -no-use-gold-linker -v -recheck
+ cd qtbase

Same here. The problem is:

EGLFS Raspberry ..... YES

Anyone knows why configure has found EGLFS Raspberry?

[SGaist]

Hi,

@themts said in Crosscompile QT 5.15.2 for raspberry pi 4 - bullseye problems:

EGL_DISPMANX_WINDOW_T

Did anyone check whether this symbol has been moved to a different header ?

The check is likely successfully because it's a minimal build that ensure the library is present which seems to be the case here. Just that symbol that seem to have disappeared from the headers included in the relevant code.

Hi,
I had the same problem.
I did this to solve the problem.

In this file ....
qt-everywhere-src-5-15.2/qtbase/src/gui/configure.json (Line about 865)

I changed the code to this ....

         "type": "compile",
         "test": {
             "include": [ "EGL/egl.h", "bcm_host.h" ],
        this line is the original, delete it =>    "main": "vc_dispmanx_display_open(0);"
        add this lines ....
            "main": [
                "vc_dispmanx_display_open(0);",
                "EGL_DISPMANX_WINDOW_T *eglWindow = new EGL_DISPMANX_WINDOW_T;"
            ]
         },
         "use": "egl bcm_host"
     },

I hope this will help you.
kind regards
