Re: [Xenomai-help] Xenomai patches

Hi Stefan,

first of all thanks for the guide. I knew more or less all the steps, but you 
have helped me a lot.

Ok, good to know. This is in same line as Gilles Chanteperdrix mail.

I don't think that this is necessary. At last I didn't need it.

I did it with dch -i . Both are valid.

it builds the tar.orig.gz

you can do it alltogether with:

fakeroot make-kpkg --initrd --added-patches xenomai --config 
menuconfig --append-to-version "-xenomai-2.4.10" -revision 1.0 binary-arch

also, instead of binary-arch, with kernel_image kernel_headers it's ok.

FANTASTIC!!!!

the CONCURRENCY_LEVEL it's great. I didn't know it!!! thanks a lot.

OTOH, the debian package has a bug. I cannot compile xenomai, using the debian 
way on kernels 2.6.28, 2.6.29 and 2.6.30 because the package add something 
that fails with make menuconfig. I should write a bug. Just for information, 
it's not a xenomai upstream related question. ;-)

Thanks for all,

Best regards,

Leo
