upgrade glibc problem
 

Hi,

I am quite inexperienced in linux. So actually I did not knew what glibc is.

I had glibc 2.2 on my computer, which has red hat linux. I tried to install glibc 2.3 rpm, but it gave some conflict errors.

Then I typed

rpm -i --force glibc2.3.X.rpm

and installed it. I did not remove the previous version of glibc.

Will this cause a problem. AT the moment it nothing seems to be wrong. But as I have read in some forums, it will cause me problems.

So how can I correct this.
Is there a way to keep glibc2.3 without getting problems. Or is there a way that I can go back to glibc 2.2 without cauisng problems.
Please help.
Thanks a lot,
Chamal.

Installing with --force option is always risky. The way to get back to glibc 2.2 is to get the right RPM (the version you had previously) and install it (with --force).

Glibc is used by many programs, so when it breakes there may be problems. The best way to update glibc is to update glibc with all programs using it. I don't know which version of RedHat you use...Do you have a tool for automatic upgrades with dependencies? Or if, you don't know, which version or RedHat do you use?

Hi Mara,

Thanks for the reply.
I am not sure which version of red hat linux I am using. How can check the version.
Also Is there a way to find out the exact version number of previous glibc. Will it be in a log file.

Do I have to remove glibc2.3 before installing the previous version or do I have to overwrite it. which way is better.

THanks a lot,
Chamal.

generally, unless your chrooted into an environment, you always overwrite. if you remove glibc, your system is hosed (even commands like ls, cd, rpm, virtually everything uses the standard c library in one way or another).
