Johnny, Thanks for expanding further on this. What you described was exactly what I was referencing. All of the stock applications work fine. I just ran into some problems with 3rd party stuff that didn't have specific binaries for the 64-bit OS.

What you want to make sure you have is a pure x86_64 build environment to build all x86_64 files. You may need these 2 files that are i[3,4,5,6]86 (and only these x86 files ... any others can produce badly built binaries). glibc.i686 glibc-devel.i386 What this means is, you can't run i386 items (like Open Office) on your x86_64 machine that you want to use for building packages. As far as all the built in server services, everything on x86_64 from a server perspective works fine (sendmail, apache, gcc, rpm-build, etc.) ... it is the mixing of shared libraries that will cause you problems if you want to build. > On 5/13/06, C..
