We have a third party shared library from a vendor that requires glib 2.15 or newer. We are using CentOS 6.6 which comes with glibc 2.12, and I know it can’t be replaced as it’s an integral part of the OS.
However, is it possible to build a glib 2.15 RPM from source to be installed in /opt/centos (or somewhere else other than /usr/lib) so that I can link the one application that requires the third party shared library with this version of glib? If so, does anyone have instructions on how to build such an RPM, or better yet, has already build such an RPM?
I don't think it is as straight forward as that ...
I did something like this _many_ years ago (to get a RedHat 9 binary to run on RedHat 7.2) - which involved copying the /lib tree from a 'newer' OS install to a separate tree - and then using the ld-linux.so.2 binary from the newer tree to load the binary - and if memory serves me right, something like (for a 32 bit binary, as they were then):
/path/to/newer/glibc/lib/ld-linux.so.2 --library-path /path/to/newer/glibc/lib /path/to/binary
You will probably have problems if the binary uses dlopen() to load other shared libs ...
I have no idea if this is still valid - as the last time I tried this was over 10 years ago ...
