The existing mkspecs for Raspberry Pi 4 (devices/linux-rasp-pi4-v3d-g++) was intended to compile Qt application for the 32-bit version of Raspberry Pi, thus it used compiler flags that are incompatible when compiling Qt application for the ARM 64-bit architecture. According to ARM compiler documentation, -mfpu flag is rejected by AArch64 state while its alternative, -mcpu, has to be avoided when -march flag is already defined. -mfloat-abi flag is not valid with AArch64 targets. To support both 64-bit and 32-bit architectures, I proposed to add this new mkspecs. See: https://developer.arm.com/documentation/101754/0618/armclang-Reference/armclang-Command-line-Options/-mfpu https://developer.arm.com/documentation/101754/0618/armclang-Reference/armclang-Command-line-Options/-mfloat-abi Pick-to: 6.3 6.4 Change-Id: I36574875e798281688601edd0f166922592d9830 Reviewed-by: Tatiana Borisova <tatiana.borisova@qt.io> Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>

# A minimal configure line could look something like this:
