[ncl-install] ncl: /lib64/tls/libc.so.6: version `GLIBC_2.4' not found (required by ncl)

[Mary Haley]

You have a rather old version of gcc.  You downloaded a version of NCL that was compiled with gcc 4.1.2. This
version will not work on your system unless you upgrade your gcc.

Even gcc version 4.1.2 is considered "old" by some standards. I mostly see systems with gcc versions 4.3 or later.

Please upgrade your version of gcc to at least 4.1.2. If you go with a higher version, then you may need to download
a different NCL binary, as we have binaries built with gcc 4.4 and later.

If you are hesitant to upgrade your gcc, then you can still install a newer gcc, but put it in a directory other than "/usr/bin so it
does't overwrite your current gcc.  I highly recommend upgrading, however.

To upgrade gcc, you can use "yum". I'm not sure of the exact package name, but it might be something like this:

yum install gcc412

You may need to use "sudo" in order to execute this command with administrative permissions:

sudo yum install gcc412
