How to recompile programs for new Linux?
I have been told that in order to make a program run smoothly in Redhat 9 which is actually made for Red Hat Linux 7.2 you need to recompile that program. How to make this?
Is there a true need to recompile program if it is made for redhat 7.2 to make it run smoothly in redhat 7.3 for example. I there so big diffrence between these two releases?
And if I upgrade my X server to latest release will my programs run after that...or is there once again need for recompiling?
