Thanks for help. I will try this in evening time today.

Eventually, you will need a C library. Newlib is the easiest to use.
Grab all of the latest toolchain from www.gnuarm.org (NOT
www.gnuarm.com) and follow the build instructions on the Support tab.
You need to build the toolchain with these instructions for it to be
aware of the library. This part of the configure command enables
newlib: --with-newlib --with-headers=[newlib-source]/newlib/libc/include
Newlib provides stubs for IO and memory management code that you have
to provide. After all, newlib can't possibly know who to send bytes
out the serial port. Heap management is another nightmare. For
examples of the stub code look at www.jcwren.com/arm Grab the Linux
download and look in the newlib subdirectory of the archive.
It is possible to build applications without using the C library but
you have to provide all of the get & put functions as well as all of
the string functions. But it can be done...

I want to know how to compile programs written in C and in assembly on Linux
based host system. I don't want to use linux on my microcontroller. I saw
that uClibc document. It seems that this library is for compiling software for
ARM microcontroller running Linux on it.
Say I just want to assemble the instruction: MOV R0, #10H
And say I just want to compile the program:
main()
{
int a,b,c;
a=3,b=5;
c=a+b;
}
How can I do it with as (gcc assembler) and gcc compiler respectively?
