[pwc] Compiling PWC

[Neil Benn <>]

Hello,

          I'm working on trying to get a philips webcam running on an
openmoko freerunner (http://www.openmoko.org).  I have installed
debian on the openmoko which comes with kernel 2.6.24.  I then
separatly compiled and install the video4linux module (with pwc driver
included).  Although this works I am getting a resolution or 120 * 60
which is pretty poor.  I am trying to compile the latest pcw to see if
that will help my problems.  I downloaded the source for 10.0;12-rc1
and patched it according to here (Path the module :
http://www.lavrsen.dk/twiki/bin/view/PWC/InstallationStandAloneModuleKernel2x6).

I then tried a compile and got this:
---

  I'm not wuite sure where to go from here, the linux source is the
complete source I used to compile the video4linux and that worked fine
(including compiling the pwc) so I'm a bit stuck.  Could anyone lend a
helping hand - I'd be most grateful.



Cheers,

Neil
