I am trying to follow the directions found here and when I run the Makefile i get
MatthewLT ~ # cd xpad
MatthewLT xpad # make
make modules -C /usr/src/linux-headers-3.2.0-23-generic SUBDIRS=/root/xpad
make[1]: Entering directory `/usr/src/linux-headers-3.2.0-23-generic'
  CC [M]  /root/xpad/xpad.o
/root/xpad/xpad.c:66:28: fatal error: linux/smp_lock.h: No such file or directory
compilation terminated.
make[2]: *** [/root/xpad/xpad.o] Error 1
make[1]: *** [_module_/root/xpad] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-3.2.0-23-generic'
make: *** [all] Error 2
MatthewLT xpad #
I have no idea what I am doing wrong any help would be greatly appreciated
