David, to be perfectly honest I do not know; this is my first ever attempt at compiling a driver. I got this far following the "Kernel 2.6 + module" instructions in http://www.saillard.org/linux/pwc/INSTALL.en (and as you can see I'm using the pwc-v4l2-20081120-042701 snapshot.) I'm guessing the answer is "outside" though, judging by this line: "make[1]: Entering directory `/usr/src/linux-headers-2.6.27-7-generic'" Looking in that path, and the directories /usr/src/linux-headers-2.6.27-7-generic/include/asm/ /usr/src/linux-headers-2.6.27-7-generic/include/linux/ the former has no semaphore.h, but the latter does. Again guessing, the kernel build tree is in /lib/modules/, and the situation is the same over there: /lib/modules/2.6.27-7-generic/build/include/linux/ has semaphore.h, /lib/modules/2.6.27-7-generic/build/include/asm/ does not have it. -- Cheers, Brynjar _______________________________________________ pwc mailing list pwc@lists.saillard.org http://lists.saillard.org/mailman/listinfo/pwc
