You are supposed to run:
make -C /path/to/your/kernel/sources M=$PWD modules
because you know how to compile kernel modules outside of the kernel
tree. You then have a ksatch.ko kernel module. It does not even work
with 2.4 kernels.
This was more intended as a test for posix shared memory and
message queues support, than as a real demo for users. I just did not
find anywhere else to put it.
What we could do is to compile the default version with -DPRODUCER
-DCONSUMER so that it would be standalone.
