Hi Thomas and Roman,
It seems to happen if I have set -mavx in CFLAGS with clang 1:3.4-1ubuntu3.
I get a different issue that only shows up at runtime in clang 3.6.2-svn240577-1~exp1:
ERROR: This system does not support "FSGSBASE".
Please check that RTE_MACHINE is set correctly.
It appears I probably need to learn how to do a better job on my EXTRA_CFLAGS. Do we have some recommendations what should be used on the different Intel CPUs to avoid build issues but still get the best performance? This would help a lot.
Matthew.
