Run "/lib64/ld-linux-x86-64.so.2 --help" - the output should include: ************************************************************************ Subdirectories of glibc-hwcaps directories, in priority order: x86-64-v4 x86-64-v3 (supported, searched) x86-64-v2 (supported, searched) ************************************************************************ So for example, the system I ran this on is -v3, but not -v4. -- Chris Adams <linux at cmadams.net>
