Comedi, ADEOS and RTAI

[galvosas at physik.uni-leipzig.de]

Hi,
After hours and days I'm lost. I hope someone could point me to the right
direction.

I want to make a RT application work with a Meilhaus me466i card, so I decided
that COMEDI is a good choice. The PC is a AMD K7 and I run gentoo.

OK, as far as I figured things out COMEDI does not work with Fusion and even
less with Xenomai (it keeps complaining that rtai.h can't be found). Am I
right?

So I switched to RTAI 3.2 with ADEOS (IPIPE is not supported, right?) with the
following configuration:

kernel:           linux-2.6.11.tar.bz2
Adeos:            adeos-linux-2.6.11-i386-r11.patch
Gentoo patches:   genpatches-2.6.11-14.base.tar.bz2
                  genpatches-2.6.11-14.extras.tar.bz2
additional patch: adeos-sources-2.6.11-r11.patch

I followed the instruction in
http://gentoo-wiki.com/HOWTO_ADEOS-based_RTAI/fusion_on_Gentoo
from which I also took the additional patch. Going on with the instruction on
this web page I installed a working rtai/fusion. All the tests are positive.

Unfortunately, COMEDI did not compile because of the missing rtai header file.

Therefore I switched to RTAI3.2 with the same kernel config as above. Here the
make stops after a good looking configure step (see below the last lines of the
output for make). Is there anyone who could help me with this problem?

Many thanks in advance
Petrik
