[cpia] Re: can't compile on RH7.1

[McQuay, Michael]

I had noticed that same thing about the video_device structure changing and
was hacking around on the cpia driver, trying to get it to work, when I saw
your email.

I just compiled 2.4.13 and, you're right, the cpia drivers that are included
with it work properly now.

I've said it before and I'll say it again, THIS DRIVER ROCKS!

Thanks to all of you who've provided a way for me to use my webcam in linux.

The problem I have is that the
/usr/src/linux/include/linux/videodev.h file defined the
video_device structure.  And that structure differs from
what the code expects.

The solution is to rebuild the kernel and select cpia
drivers at that time. Then the camera works.  Make sure you
also select the usb options that are listed in the cpia
docs.

This appears to work -- friends of mine did this, I haven't
gotten that far yet   :-)

Good luck.

David

 Oops, except that mine also has the following lines at the
bottom.


cpia.c:3917: warning: initialization makes integer from
pointer without a
cast
cpia.c: In function `cpia_register_camera':
cpia.c:4079: too few arguments to function

I'm having the exact same problem/errors as you described
below.

Have you found a solution, yet?

If I find a solution, I'll post it.
