Hello Everyone,
for a small embedded System i would like to install CentOS, but it is a RISC System. So my Question is it possible to rebuild some SRPMs for RISC?
Thanks in Advance Daniel

You'll have to be more specific.
What architecture of "RISC"? If it isn't already available, you may want to check out another source like Debian.
I suspect from the quality of your initial question, that you don't have the skills to built a distribution. So go to a source that already builds for your hardware.

Some risc systems are quite big: IBM's Power* and Sun's *sparc* are risc systems.
However, for embedded systems, I suspect you're talking about small systems, and RHEL/Fedora/CentOS are quite unsuitable. Don't think about any of them unless you have _at least_ 256 Mbytes of RAM and a few gigglebytes of disk.
Debian's not going to work, by itself, with a diskless system, though it probably has the cross-development tools you will need.
Google around for your architecture + Linux + development.
Speaking of Debian, would you believe its most popular architecture is, Not IA32/AMD-64, not Power, but ARM?
Does it have to be Linux? One of my mates has a Zaurus, and he's recently installed a BSD on that.

512Mb of ram (256 for /var /tmp, 256 for working memory) and 512 of flash memory for the OS : You can use RHEL/CENTOS for "big" embedded system (with C3 i686 cpu) I think you can use 256 mb of ram and 256 mb for flash, but .. it's still a big one :)

take a look at uClinux and Busybox, and the various embedded projects using them, like openwrt.

Depending on the environment, this is probably a useless waste of CPU cycles, memory, and precious storage space :). As other suggested, you may want to look at Busybox.
<semi-ot> If the system has a MMU, NetBSD is also a good option. It can fit in low memory environments, and can easily be cross-compiled on any architecture you prefer. The miniroot build infrastructure bits show how one could build a small system. Of course, you could also use precompiled binary sets plus pax and mtree. </semi-ot>
