Hi All,
I am trying to cross compile rt-tests on Ubuntu with 64bit cross gcc
tool chain and ended up with below error (Able to compile successfully
with 32bit tool chain). Can someone help clarifying the below error?
Is this the issue with syscalls or with linux kernel version. How to
get it compile successfully for 64bit ARCH.
