I would like to try G-WAN but our server runs on RHEL5. I understood G-WAN needs glibc 2.11 (GLIBC_2.6) in G-WAN 3. Is there a version for RHEL5, source code, G-WAN 2 or any other way around this?

What is the GLIBC version for RHEL5?

Looking at the latest G-WAN machine code, I found only a few calls for GLIBC > 2.0 so this could be resolved with dynamic linking. I will try to make it work for the next release but to be 'sure' that it will work for you we need to know your version of GLIBC.

  • I think this is a matter of compilation. ./gwan: /lib64/libc.so.6: version `GLIBC_2.6' not found (required by ./gwan) – Antti Rytsölä Nov 19 '12 at 14:52
  • These are found in RHEL5.8, glibc-2.5-81: $ strings /lib64/libc.so.6 | grep GLIBC GLIBC_2.2.5 GLIBC_2.2.6 GLIBC_2.3 GLIBC_2.3.2 GLIBC_2.3.3 GLIBC_2.3.4 GLIBC_2.4 GLIBC_2.5 GLIBC_PRIVATE – Antti Rytsölä Nov 20 '12 at 08:27
  • Thank you anttir, that confirms the idea that, to be 'safe', only a GLIBC calls should receive a special treatment. – Gil Nov 22 '12 at 14:33

I had this issue too. Here's the deal.. glibc needs to be upgraded, this is system-wide. If you upgrade it you'll end up breaking LOTS of other things.

My suggestion is to either upgrade RHEL, try it in a virtualized environment on the RHEL install, or see if you can do it on a different machine.

For my case, we ended up migrating to a different machine.

  • Great work, Gil! The G-WAN team's responsiveness and attention is excellent. Do we have an ETA on when we'll get access to the next G-WAN version? – Tango Bravo Nov 27 '12 at 16:42
