I'm afraid qtbase-opensource-src currently does not cross compiles using normal Debian techniques because we could not fix the qmake bootstrap in it. > I tried to 'chroot' a rootfs for aarch64, and use qemu-aarch64 tools to > cross compile, but it's too slow. > > Could you provide any document for cross comiple qtbase5-dev package on > x64 architecture? The only way I can think of is: - Install qemu-user-static - Create an aarch64 chroot - Mount /proc, /sys, /dev and /dev/pts in it - chroot into the chroot - "natively" compile there. Yes, it **will* be slow. And I can't warrant it will work. Cheers, Lisandro. -- Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
