Cross compile build fails with qgrayraster.c
-
Hi, I am cross compiling qt 6.4.2 using https://wiki.qt.io/Cross-Compile_Qt_6_for_Raspberry_Pi as my rough guide.
I am using a tool chain from https://toolchains.bootlin.com/releases_aarch64.htmlAfter a lot of fiddling I ended up getting a successful config with the following config command:
../qtbase/configure -release -opengl es2 -nomake examples -nomake tests -qt-host-path $CROSSCOMPILE/qt6/qt-host2 -extprefix $CROSSCOMPILE/qt6/qt-raspi2 -prefix /usr/local/qt6 -device linux-rasp-pi4-aarch64 -device-option CROSS_COMPILE=aarch64-linux-gnu- -submodules qtwayland -- -DCMAKE_TOOLCHAIN_FILE=$CROSSCOMPILE/toolchain.cmake -DQT_FEATURE_kms=ON -DQT_FEATURE_opengles2=ON -DQT_FEATURE_opengles3=ONbut upon trying to build I get some errors, the first of which is:

Any idea welcome. Thanks!
