Program compatibility between solaris and Linux??

Hi!
I have a question about the program on different operation system.
I run my program on the Linux. The result is right, but in the Solaris. The result is wrong. So, is the difference between the Linux and Solaris? Where can I reference or get some information about that. Thank you!!

What lang, what versions of Linux, Solaris?
If shell script, ensure using same shell by specifying
#!<pathtoreqdshellbinhere>
as first line.
If another script lang eg Perl, check #! entry for correct path.

Hi, I use C language. The versions of Linux, Solaris are 6.3 debian and sparc-sun-solaris2.6

Are you running both OSs on the same computer? If not, do both computers use the same CPU family?

I'm asking this because Sun computers use big-endian CPUs, whereas "normal" PCs use little-endian. This can cause all sorts of strangeness.

What functionality are you using? Is the program threaded? Are you using any networking or socket code?

What compiler/version are you using under Solaris?

I seriously doubt this is an endian issue unless you attempting to run the Linux ELF binary on Solaris... which would probably fail for a number of reasons before the big vs. little endian issue would even have a chance to matter

It would help if you:
- tell what your program is doing
- narrow the difference to a small piece of code
- post this code sample
- tell what is the expected result and the returned result with Solaris.

As jtshaw said, copying binaries across these OSes is not going to work... this is true across almost any different OS pair.
You will have to re-compile at a minimum.
