(5.6 is 2.6.18-238.x.y.el5). Doesn't really make a difference, but felt compelled to point it out. :) > make -C /lib/modules/2.6.18-194.32.1.el5/build SUBDIRS=/home/silentm/MessageNet/v4l/new/v4l-dvb-3724e93f7af5/v4l modules > make[2]: Entering directory `/usr/src/kernels/2.6.18-194.32.1.el5-x86_64' > CC [M] /home/silentm/MessageNet/v4l/new/v4l-dvb-3724e93f7af5/v4l/tuner-xc2028.o > In file included from /home/silentm/MessageNet/v4l/new/v4l-dvb-3724e93f7af5/v4l/tuner-xc2028.c:19: > /home/silentm/MessageNet/v4l/new/v4l-dvb-3724e93f7af5/v4l/compat.h:133: error: static declaration of 'strict_strtoul' follows non-static declaration > include/linux/kernel.h:141: error: previous declaration of 'strict_strtoul' was here The above lines tell you exactly what the failure was, and its easily worked around by removing the extraneous definition from v4l/compat.h. > Is there a way I can just compile the linux/drivers/media/video/uvc ?

Another option you can try is something along the lines of this: cd linux/drivers/media/video/uvc make -C /lib/modules/2.6.18-194.32.1.el5/build M=$PWD modules No guarantees that won't fail miserably though. Backporting newer drivers to older kernels often takes a fair bit of effort and subject matter expertise -- especially when the kernel base is as ancient as the one you're targeting. There's a reason media_build doesn't support anything that old. :) -- Jarod Wilson jarod@xxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
