[uml-devel] building from source

[uml-devel] building from source

[atanugul]

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?

Thanks,
Ashwin.

You should use either 2.4.26-3 on a 2.4.26 vanilla kernel or 2.4.24-1 on a 
2.4.24 vanilla kernel. All the releases between those two have various 
problems. In fact, the 2.4.26-3um patch fixes exactly this problem (which 
happens because you enabled CONFIG_SMP).

The messages you get are fine ... the problem is that the version you used is 
botched. Use 2.4.26-3 and you'll be fine. Alternatively, IIRC if you redirect 
stdin and stdout somewhere else it will maybe work (use /dev/zero for stdin).

I.e.
linux ubd0=/uml/root_fs_debian2.2_small < /dev/zero | tee UmlOutput
