My OS is 64 bit version and I tried with installing glibc i686 version because of this issue.But I'm facing the same issue again.

Answer 1

On a 64 bit Fedora system, both 32 bit (ex: glibc-2.14.90-14.i686 ) and 64 bit (ex: glibc-2.14.90-24.fc16.9.x86_64 ) library must be of the same version.

The solution has already been posted in the Fedora official forum.

1. package-cleanup --dupes
2. package-cleanup --cleandupes
3. yum clean all
4. yum update
5. yum install gcc
