Subject: Re: patching a kernel
That was the way it always used to work, but lately, speakup uses git and
the checkout script only works up to kernel 2.6.21.x and i am not sure
what number x may be.
I'm not 100% sure but Ibelieve x=22. 2.I'm not sure it was possible to patch
a 2.6.21 kernel because the kernel team had inplemented some changes to how
the kernel uses serial ports which were incompatible with speakup. But these
changes were backed out for other reasons in the 2.6.22 kernel code.
Below is a Makefile that I use to build a kernel. There's a git-clone
command in there that will work even if you type it in yourself rather than
using my Makefile. If you put this file in /usr/src, it will download the
kernel source, uncompress it, apply the speakup patches, and then crash, I
think. But that's not bad because at that point you have to configure the
kernel anyway. After you create a /usr/src/.config file, you can run make
again and it should build a debian kernel package for you.
