When i try to include "stdio.h" in my project and use sprintf();
function, i get all kind of errors, whay is that? If i include
"math.h" for instance, i have no problem.

You are lacking a suitable syscalls object for your platform where
these functions are located. The missing functions are low-level IO
routines, newlib has no idea about what hardware is is running on.

You normally have to supply these functions yourself, unless you are
using a platform where somebody else has written one.

Does sprintf() need to know anything about IO. I would like to do anly
some int to string conversion.

Is there a complete library for winarm that includes sprintf(), itoa()
etc?

Take a closer look. The errors are complaining about the lack of
interworking not missing functions. WinARM include newlib-lpc to provide
the hooks. The problem is they are not compiled for interworking.
Actually unless the OP has a space problem I'd recommend sticking with
straight ARM to begin with rahter than introduce thumb and interworking.

The second problem is the I/O device table is missing. Take a look at the
examples, that should show how to set one up for stdio.

Now as for sprintf requiring the stream I/O functions....

You could try searching the web for the source code to sprintf and
forget NEWLIB.

There was a similar thread a few days ago and I posted a simple
syscalls.c but I doubt it will work with newlib - it certainly
works with libc and libgcc though - its what I use.
