hi andy,
it's probably fine for experts like yourself to use non-supported OS's,
but i wouldn't recommend it for non experts:
we have run into some strange and subtle problems that i wouldn't have
guessed would be operating system related. for instance, some of the FFT's
in the simulink library produce incorrect output for length > 2K points;
these numerical errors only occur with some of the non-supported
operating systems.
and there's no error message to warn you that there might be a problem.
if you use red hat enterprise or other supported operating systems,
then the FFT's produce correct results. we don't know why;
it was sufficiently scary that we only work with supported OS's now.
another problem with non-supported operating systems is that xilinx
refuses to help you. if you email or call xilinx support with a
question,
they ask for your operating system. if it's not a system they support,
then they tell you to try your design on a system that they support; if the
problem persists on operating system they support, then they will research
your question and try to help you.
best wishes,
dan

hi daniel h,
i suggest casper collaborators only use one of the operating systems
supported by xilinx. see the list of supported OS's at:

I think Daniel said that Ubuntu is working but CentOS isn't.
Can you run strace -o<some file> -f xlcm, gzip the output, and send it?
(FWIW, this stance of "use a supported OS" is starting to drive me
nuts. I have a Fedora 13 install that works swimmingly and an RHEL 5
install that gives me no end of trouble.)
