[Mesa-users] Installation of new version.

[RICHARD H D TOWNSEND]

Hi Ben (cc'ing mesa-users, since we should keep them in the loop) --

This all looks fine, so my hunch that something was going wrong with libraries doesn't seem to bear out.

For those reading this thread: what's happening is that show_rates on Ben's machine is giving slightly different output in the last (decimal) significant digit. Not sure whether there is some code in rates that isn't using crlibm, or whether this is a fundamental breakdown of bit-for-bit compatibility.

Ben, it would be interesting to see what processor your computer uses. Can you post the output from 'cat /proc/cpuinfo'.

cheers,

Rich
