How to install glibc in a centos server

Make sure you have your development tools installed:

yum groupinstall "Development Tools"

Grab the src rpm:

wget http://xmlsoft.org/sources/libxml2-2.7.8-1.src.rpm

you won't be able to call rpmbuild directly, due to rpm version differnces, so lets short circuit that:

rpm -ivh libxml2-2.7.8-1.src.rpm --nomd5

then:

rpmbuild -ba /usr/src/redhat/SPECS/libxml2.spec

you may be prompted for some dependencies at this point (if so, just yum install the dependencies in question, then rerun the rpmbuild -ba command above).

Assuming your build completes successfully (I just tested this on a CentOS 5 box here, and it built fine), the resulting RPMs will be in:

/usr/src/redhat/RPMS/arch

where "arch" is x86_64 or i386, depending on your system. You can yum localinstall --nogpgcheck the packages from there.

The package is called postgresql-libs on Red Hat and derived distributions.
