Hi,
We are going to use the Roach board (arriving soon!) for a
proof-of-concept design. I am in the process of setting up the toolflow
and I need to decide between windows versus RHEL. I read the following
thread dated mid-March:
http://www.mail-archive.com/[email protected]/msg01328.html
Has this recommendation changed since?
Thanks,
Mandana

I too find RHEL a very frustrating OS to use on a day-to-day basis.
But it seems the Xilinx tools rely on some of those ancient libraries
that RedHat packages. We've had some success with installing newwer
Debian-based distros, and then manually adding the older libraries
(perl is the big annoyance). But this is far from reliable and not
recommended. As Dan says, we've found some quirky behaviour where some
designs compile and others do not.
If you insist on running something other than RHEL (as I do), then I
can suggest you get yourself a copy of the full RHEL5 root filesystem
and do a chroot before starting matlab/xilinx tools. It works
reliably, but is painful to setup (not to mention that it consumes
~20GB of diskspace). This is not something a Linux newbie should try
and is not recommended for those who are not familiar with these tools
and concepts. You can also do things like faking the hostname (using
chname) and the ethernet adaptor's MAC (must be eth0; set up a null
tap device) to ease licensing troubles when upgrading or moving your
compile environment to a different hardware platform. In this way, as
far as the toolflow is concerned, the system is RedHat (apart from the
kernel, which is mostly the same).
I mention this to illustrate that there are other toolflow
possibilities. But please note that this is not a CASPER recommended
configuration and we can not (and will not) offer support for anything
other than a vanilla RHEL5 install.

hi bay, andy,
i strongly recommend using Xilinx supported operating systems
(eg: RHEL5).
we've encountered some very strange bugs with other
linux variants - these bugs don't appear like they might be operating system
related, but when we switched over to RHEL5, the bugs vanished.
also, xilinx will refuse to answer questions if you aren't using one of the
operating systems they support.
i'm hoping the bulk of the casper community will use RHEL5 or another
xilinx supported system so we can all help each other.
our group has switched to RHEL5 and i recommend it to other groups.

Hi Bay,
We had to move to RHEL5 (64-bit ok) to get versions above 11.3 working.
I've heard that CentOS works too.
And you really need 64 bit...
We're in the process of setting up a Fedora 13 system, since it's
annoying to have packages as old as RHEL's. Has anyone had any
trouble with that?
(There's also RHEL6 Beta, but I haven't gotten that to install without
crashing, so I don't think it's quite ready for prime time.)

We're setting up a new toolflow computer after Ubuntu stopped working.
Should we be installing RHEL 64-bit install or 32-bit? The wiki
mentions
64-bit in passing, but I remember there being some problems with 64-bit
earlier...
