Installing NCL under Linux systems

If you are installing pre-compiled NCL binaries on a Linux system, there may be a number of binaries to choose from. To know which ones to select, type the following to get the type of system you have, and the version of gcc:

  uname -m
  gcc --version

If these two comands report "i686" and "4.1.0", then you need to download the Linux binary for an i686 system running gcc version 4.x. This binary will be labeled on the ESG page as something like:

NCL 5.0.0 32-bit binary for i686 chips for LINUX (compiled with gcc 4.x)

Note that the version of gcc may not be exactly 4.1.0. As long as it is 4.x, you should be okay.

If these two commands report something like "x86_64" and "3.4.6", then you need:

NCL 5.0.0 64-bit binary for x86_64 chips for LINUX (compiled with gcc 3.x)

If these two commands report something like "ia64" and "3.4.6", then you need:

NCL 5.0.0 64-bit binary for IA64 chips for LINUX (compiled with gcc 3.x)

and so on.
