Re: Kernel compilation failure

[Gilles <gilles@harfang.homelinux.org>]

Hi.

[In the meantime, I did an "apt-get upgrade" which seemed to have
solved the "unknown architecture" error message.  Also, I think
that last time I successfully compiled the kernel, the default
was "gcc-3.3" while now "gcc" points to "gcc-4.0".]

Following your advice, this is now the command I entered:

 MAKEFLAGS='V=1' make-kpkg --append-to-version +g2 kernel_image modules_image

And here are the messages:

Trying a second time, it stopped (much earlier) at:

Thanks for your help.
