I downloaded the 2.6.29.4 kernel source from kernel.org, and extracted it to /usr/src/. I downloaded RTAI 0.7.1 and patched the kernel, configured it, compiled it, installed it, rebooted and ran it.
Now I am trying to install comedi and comedilib. I got the tarballs off the web from comedi.org.
comedi-0.7.76 was extracted to /usr/local/bin
comedilib-0.8.1 was extracted to /usr/local/lib
I went back into my /usr/src/linux directory and edited the makefile to reflect my extraversion.
$ ls -l /usr/src
lrwxrwxrwx 1 root src 31 2009-08-05 13:53 linux -> linux-build-2.6.29.4-rtai-3.7.1
drwxrwxr-x 23 root root 4096 2009-08-06 00:41 linux-build-2.6.29.4-rtai-3.7.1
drwxr-xr-x 21 root root 4096 2009-08-05 15:08 linux-headers-2.6.29.4-rtai-3.7.1
$ uname -r
2.6.29.4-rtai-3.7.1
$ sudo vi /usr/src/linux/Makefile
EXTRAVERSION = .4-rtai-3.7.1
I then cleaned up the area and prepared it for comedi
$ cd /usr/src/linux
$ sudo -s
# make clean
# make mrproper
# make oldconfig
# make modules_prepare
# exit
Then I tried to compile comedi
$ ls -l /usr/local/bin
lrwxrwxrwx 1 root root 28 2009-08-05 15:27 comedi -> /usr/local/bin/comedi-0.7.76
drwxr-xr-x 8 daq daq 4096 2009-08-06 01:00 comedi-0.7.76
$ cd /usr/local/bin/comedi
$ sudo -s
# ./configure
At this point I expected to be asked questions about configuring comedi for national instruments boards, however, the script ran without any intervention on my part. :confused:

I then checked to see if the comedi kernel module was compiled
$ ls /usr/local/bin/comedi/comedi/drivers/comedi.ko
ls: cannot access /usr/local/bin/comedi/comedi/drivers/comedi.ko: No such file or directory
$ ls /usr/local/bin/comedi/comedi/drivers/*.ko
ls: cannot access /usr/local/bin/comedi/comedi/drivers/*.ko: No such file or directory
At this point I dont see why it fails, but I believe this is the reason why I haven't been able to proceed to loading the ni_pcimio module. Most of the help I've found on the web has not helped. Getting comedi to compile is difficult because it depends on the kernel headers. I thought I had all that sorted, but I'm thinking I'm missing something.
Any help would be appreciated.
