I have a fedora 4 installed on my computer and it has glibc version 2.5.3, but I want to install a software that needs a glibc 2.7+ . On the other hand, I have some programs that need this 2.5.3 version. I have three questions regarding this problem:

  1. How can I install another glibc on my system and still keeping the 2.5.3 as default
  2. How can In pass the address of new glibc to the program that I am going to install (is it an option in ./configure ?). The software that I am going to install is nodejs.
  3. In future, how can I tell my softwares which glibc to use?

Hi and welcome to Unix & Linux. Please don't cross post questions across the various stackexchange sites. I see you posted this question as well on Super User. superuser.com/questions/590495/…. See here for more info: meta.stackexchange.com/questions/141823/… –  slm May 2 '13 at 9:26

On a side note: Fedora 4 is no more supported since a long time. If your system is online I would strongly suggest to a system with security updates ... –  Matteo May 2 '13 at 9:55

This is classical sysadmin problem, if I get it right, this tool is just what you need:


What it does is control environment variables, if you want to load a specific version of glibc you need to put it on the LD_LIBRARY_PATH (and ideally remove the other one), same deal with programs and applications.

The environment is controlled by loading and unloading modulefiles, the syntax for those files is explained here.

there is no LD_LIBRARY_PATH variable –  emab May 3 '13 at 12:12
That's because you are using only the default paths, if you define LD_LIBRARY_PATH with some custom library and compile with that library the compiler will search in the LD_LIBRARY_PATH and the default places (I'm not sure the about the search order) –  RSFalcon7 May 4 '13 at 12:49

Whatever needs glibc-2.7 won't run on Fedora 4 (for lack of other libraries, or missing kernel features).

Fedora 4 is now 7 or so years old, out of any support for 6 years. Update.

Nope, I am now running a few programs that use glibc-2.7!!!! –  emab May 3 '13 at 12:11
@emab, update now. –  vonbrand May 3 '13 at 14:47
