Qt 6.0 build from source on Raspberry Pi 4 "Opengl functionality tests failed"

[hareendran-tl]

@jsulm
This is the error i getting.

ERROR: The OpenGL functionality tests failed! You might need to modify the OpenGL package search path by setting the OpenGL_DIR CMake variable to the OpenGL library's installation directory.

CMake Error at qtbase/cmake/QtBuildInformation.cmake:181 (message):

I am having the same problem on a RPi3B+, did anybody manage to solve this?

@Dane-0 Check config.log file which contains the build log. You should find there error messages - post them here.

I have been struggling with this for a few days now :-D.
I noted at "Performing C++ SOURCE FILE Test HAVE_GLESv2 failed with the following output" that there were errors like "undefined reference to `_dl_addr@GLIBC_PRIVATE'". I inspected libc.so.6 with nm and saw that these were indeed missing, so I downloaded a cross-compiler from the ARM website and tried that one, however that one fails with the following:

I tried copying the libc.so.6 from the downloaded compiler over the ubuntu-package one, which then resulting in errors regarding pthread.

This looks similar.

@Dane-0 I had this exact same error following the cross compile procedure for Rpi4 from a host-machine (ubuntu22 on a x86 computer) any solution?
