Qt crosscompile for buildroot Raspberry Pi
-
Hi
I am trying to cross compile Qt everywhere against buildroot Raspberry Pi I have stored in sysroot. After I run ./configure I get this error:
ERROR: Cannot compile a minimal program. The toolchain or QMakeSpec is broken.I can compile against full image (rootfs) of Raspberry Pi with no problem!
What am I missing?
kind regards Thomas
