The installer queries the CPU for supported flags, and selectes the higest available. (If you're interested in what your cpu supports, you can take a look at the cpu-z utility http://www.cpuid.com/cpuz.php). No I suspect that something is wrong with gcc-4.4.0 and atlas which is built with gcc-4.3.0, since the atlas library is the same as for previous binaries, but I switched to gcc-4.4.0 for the 3.2.3 binary. benjamin ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
