Subject: Is it possible to compile on one Linux and run on another
Linux?

Usually, different Linux version will have a lot of libraries version
changed (Of course, I just mean the situation that both environments
have related libraries, but version changed.). So is it possible to
compile on one Linux and run on another Linux?
If it's impossible or very hard, then how could so many products which
only provide one binary for installation and can be installed on
several systems like Redhat4 and Redhat5?
How they achieved this? Or what shall we do to ensure that? I have
tried, it seems normal dynamic/static link is not the right solution.

As long as they have the same architecture and reasonably closer
libraries versions.

They don't have to be the same architecture or have the same
library versions if you've installed a cross-compiler and the
proper target libraries.

Compile what? If you're talking about a simple program - yes. If you're 
talking about the kernel - more problematic.

It is possible, we do it at work, but it is not always easy. You may
have to carry some libraries with you.

         more readers you will need to find a different means of

Compile with the -static switch, which prevents linking
with shared libraries, and the resulting executable
image is usually portable to other linux boxes, e.g.,
   gcc -static program.c -lm -o program
builds program with any needed library routines statically
linked into the image.

I am sure I have try my best to link to libraries statically. But it
seems libraries I have static-linked have dynamically linked to other
dynamic libraries. Now, my program will complain that some libraries
with minor version number like 'libldap-2.2.so.7' can't be found
(because the existing ldap library has version number as 2.3.0).
I am afraid I have no choice but to deliver some libraries with my
program. Terrible thing.
