[Xenomai-help] pipe.ko

Hi, I got compiled the example pipe.c in your two parts (kernel and user
space). Trying to load the file pipe.ko I got returned:

sh-3.00# insmod pipe.ko
insmod: error inserting 'pipe.ko': -1 No such device

Am I missing something? Should I load another module before?

Thanks,

Breno

The snippet in question is just a skeleton; what actual code are you compiling?

"No such device" == ENODEV. You need to find the reason why init_module()
returns ENODEV. Hint: rt_pipe_create() may return -ENODEV, the native API
documentation says why.
