[Pxc] I had the same trouble as Tye Brady. Any solution?

[Tye Brady]

Hi Jeff,

First let me thank Alessandro for writing the device driver and the prompt
response to my question.  It really helped me out (BTW his book is awesome
on writing device drivers).

OK the solution for me was to pitch the "prebuilt" kernel for me that
came with RH7.0.  Whatever was happening, it was incompatible with
this kernel "they" (ie. RH with the 7.0 dist) built on my machine
was not working very well with ANY loadable modules.

What I did then was download 2.2.18 source and recompile the kernel myself
so that I could know exactly what it was I was running.
This sounded easy enough but for a newbie like myself, I tripped multiple
times on the job.  The hardest trip BY FAR was the fact that the compiler
that comes with RH7.0 has a major flaw in it that does NOT allow you to
compile kernels!  The solution is to use KGCC and not GCC that comes with the
distribution.  After that was cleared up, I was able to compile the kernel
and *without a hitch* run the PXC drivers.  Works great.  If you need help,
I can point you to many references.

I also use bttv0.7.59 with i2c-2.5.5 to run XAWTV and bttvgrab quite nicely.
I believe they incorporated Alessandros drivers and work.  Just for reference
for you lab types that might be interested, I am also running a GPIB board
inside the linux box and doing data collection simultaneously.  It is all
playing nicely.

My personal application is a machine vision like task of trying to measure
the drift of a star in a CCD camera.  I would like to locate the object
in the camera, stay locked on to it, and then measure how much it moves
in a certain amount of time.  If anybody has any references to any code
or solutions, that would be GREAT!

HTH,
Tye
