It depends on the library versions that you have compiled it against, 
mainly glibc.

Most definitely they should be same :)

That is not much of a problem since you don't directly interact with the 
kernel. All the functionality will be exposed through glibc.

If you are making a custom app, your best bet is to package it as a rpm. 
rpm format will encode all the dependencies and print out suitable 
errors if compatible libraries are not found.
