CentOS6 64-Bit OS Upgrade

We have been working on getting our Operating System on the Linux side upgraded to a much newer version. This enhances our systems to run with some of the latest drivers and applications. This is also a 64-bit OS.

Here are some tips on the new OS.

  • All binaries/scripts have been recompiled on 64-bit (and /or compatible) with this environment
  • Most revision of software are now the latest
  • If you want to compile 64-bit code, you may need to set up some environmental variables before recompiling.

Recommended
Store your 64-bit code, binaries and libraries in a separate directory since we still have 32-bit systems available

  • To compile your code on the new Operating System (newindigo),you may need to set up environment variables

setenv LD_RUN_PATH “/cse/local/lib64”

 setenv PKG_CONFIG_PATH "/cse/local/lib64/pkgconfig:/usr/lib64/pkgconfig"
  • Be aware if you log into other 32-bit systems and try to run your 64-bit code, it will not run, hence the reason to put your 64-bit programs, libraries in a separate directory
Major Program Changes
  • OpenOffice has been replaced by LibreOffice (v3.4.2)
  • The GCC compiler has been updated to v4.4.4 (default), v3.4 is still available
