Also there is a new instruction for Rasp + Qt6: https://wiki.qt.io/Cross-Compile_Qt_6_for_Raspberry_Pi

@Milav said in segmentation fault: the difference between host pc and Embedded target board is only QT source. Host pc => qmake (qt version 5.4.0 ) Embedded target => qmake (qt version 4.8.7) You should have stated these settings from the very beginning... :-) Anyway, could it be possible that you build Qt 4.8.7 for PC (host) and build your example again with that Qt version and run in PC to see what happens.

been a couple days since I have looked into this, but went in and modified the /bits/syscall.h file by simply adding the syscall number for renameat2 was able to run the configure command and got this error at the end: ERROR: The OpenGL functionality tests failed! You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2], QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform. Check config.log for details.

Update: This is definitely not a problem with Qt or Qt Creator. I tried building it with Android Studio and got the same problem when I used gcc, and a different problem when I used clang (no errors, but no output). I was able to build it from the command line using the make_standalone_toolchain.py utility from the Android SDK and CMake.
