Hi,
I've been thinking of using UML to prototype RHEL v4 based solutions
before deployment in real environments. I therefore want the kernel
to be as close as possible to the Red Hat supported kernel. I found a
similar thread about a month ago
(https://www.redhat.com/archives/nahant-list/2006-August/msg00299.html)
but unfortunately, Rik didn't follow up on the thread. The problem is
as follows:
1) I download the src rpm
2) I installed it and then ran rpmbuild -bp --target=i686
kernel-2.6.spec (unfortunately, there is no --target=i386)
3) I then cd into /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/
and
cp configs/kernel-2.6.9-i686.config .config
4) I then run:
make ARCH=um
and I select some options. However, it then exits giving the following
error:

Any ideas? Thanks for your help.
