Problems w/ different platforms?

[Qin Tao <qtao@mars.iol.unh.edu>]

Hello,

Did anybody have problems caused by platform differences? For example,
did you ever compile and run a program on one linux distribution w/o
problems while have troubles to deal with the same program on another
distribution?  If so, could you please let me know what is your problem
and how you solved it? Does anybody have any experience to avoid the effects
on compiling and runing programs from different platforms ?

Any response to the above topics will be greatly appreciated!! Your rich
experience is a huge help to me.

Thanks in advance.
Qin
