Hi!
I tried building a uml kernel from source.I have a debian 2.6.6 kernel on
my system. I downloaded a 2.4.26 kernel and a matching uml patch
(uml-patch-2.4.26-1.bz2) for it.I followed the steps specified in the
user-mode-linux. Everything went well till step 5. When I did `make linux
ARCH=um' I got the following error messages:
make -C arch/um/sys-i386/util mk_sc

Can anyone tell me what i should do?
