Hi all,
I am following this Qt article about how to cross compile Qt for Raspberry, but I am getting problems for generate the Qt 6 binaries for aarch64 using the Raspbery Sysroot. I am using Ubuntu 20.04 on a virtual machine and Qt 6.6.0.Compilation output :

@adrianomunin What are you using for cmake, did you apt install or build from source?
