====== 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  * OpenOffice has been replaced by LibreOffice (v3.4.2)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
