Linux is supported in many hardware. Some of them are:
* Alpha
* ARM
* HP PA-RISC
* Intel x86
* Intel IA-64
* Motorola 680x0
* MIPS
* MIPS (DEC)
* PowerPC
* IBM S/390
* SPARC
I make program and use many function like:
fork(), pipe(), execlv(), semaphore, and so on. However because I only have Intel x86 hardware, I am just curios will my program be compiled correctly in other hardwares?
A man asked, "Who are you?"
Buddha answered, "I am awaked."
If you write Linux code for one machine, then you can reasonably expect it to compile and run on all other Linux machines without modification. Everything is derived from the same code base, so you'd have to dig pretty deep into some dark corner to get any real idea of the differences between hardware platforms.
If you stick to the POSIX interface, then you can reasonably expect it to compile on all Unix and Linux machines. This is mostly achieved by the use of "autoconf" to assist with many common portability problems.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
