Raspberry Pi 4 cross compile trouble
-
Greetings everyone!
I have encountered a trouble while trying to create a cross-compile toolchain for my Raspberry Pi 4 with newest Raspbian x64 Bookworm.
I have followed this instruction: Cross-Compile Qt 6 for Raspberry Pi, to get the whole thing work.
I am using Debian 12 latest official release.
The problem itself reveals when I am trying to build a project within Qt Creator. I am making a kit by the instruction - adding aarch64 compiler (12.2) that was used to build qt, qmake that I have got in qt-raspi catalog after the build of qt, but when I stepping to qmake of my project, I got the following error:Project ERROR: Cannot run target compiler 'g++'.

Re: Raspberry Pi 4 cross compile trouble
The problem solved in another way - seems that we now have to use CMake instead of QMake for qt based crossplatform solutions for arm.
So I just made CMakeLists.txt - configured my project again and everything get working.
Of course that was painful for a bit (never used cmake before) but you always need to go further and to learn instantly. -
