I tried to install gspca to run Orite webcam on Ubuntu 12.04 64-bit, but I failed.

It lost a lot of headers, here are my instructions but failed.

  wget http://mxhaard.free.fr/spca50x/Download/gspcav1-20071224.tar.gz
  tar zxvf gspcav1-20071224.tar.gz
  cd gspcav1-20071224/
  sudo ./gspca_build
  sudo touch /usr/src/linux-headers-3.2.0-25-generic/include/linux/config.h
  sudo mkdir /usr/src/linux-headers-3.2.0-25-generic/include/asm
  sudo touch /usr/src/linux-headers-3.2.0-25-generic/include/asm/semaphore.h
  sudo touch /usr/src/linux-headers-3.2.0-25-generic/include/linux/videodev.h
  sudo touch /usr/src/linux-headers-3.2.0-25-generic/include/linux/smp_lock.h

How to solve it?

I move to /usr/src and make:

  sam@sam:/usr/src/gspcav1-20071224$ sudo make
  make -C /lib/modules/`uname -r`/build SUBDIRS=/usr/src/gspcav1-20071224       CC=cc modules
  make[1]: Entering directory `/usr/src/linux-headers-3.2.0-25-generic'
