Hi Duleep, I never used Centos, but I don't see any reason why OsmoGGSN wouldn't compile or run fine. OsmoGGSN is known to build and run fine in other Linux distributions like Ubuntu, Debian, OpenSuse, ArchLinux, OpenEmbedded etc. I personally found some build issues while building it in some old Yocto/OE poky release using old kernel and libc combination due to ipv6 support including ipv6 headers which didn't have proper UAPI support at the time, but I don't think you are going to run into this issue. The only problematic support you may find is in case you want to enable GTP in kernel. You'll need to build/install libgtpnl and make sure your kernel supports it, but you can run totally fine without this feature too otherwise.
