Check the Makefile for your preferences, then type make Once the utils have compiled you can test the modules interface by installing the hello world device driver. To build the utilities, type: make To test the package, type: make test You can also go to the "./DEMO/Stacking" directory and type: "demo" To install the utilities, type: make install You might want to change the BINDIR in the makefile first. A quick look in the man pages is a good idea right now... To experiment with the example driver use: insmod drv_hello.o Then to check it works, make sure that the special file "/dev/hw" exists, otherwise create it with mknod /dev/hw c 42 0 You can see the driver in all its glory with cat /dev/hw Use lsmod and rmmod to check its existance and remove it. Then write new drivers for all your favourite toys. Jon (and Bjorn).
