How to build RTAI Kernel for stetch?

Solved by installing xinput separately, all functions now work fine until the next break.

Which kernel version would you need? The latest patches seem to be for 4.9.51 and 4.9.80

I think it does not matter which kernel, it should just be 4.<something>, 'cause I cannot compile linuxcnc when I use the ancient 3.<something> RTAI kernels.

My status now is: I can apply the rtai patches to the kernel without error. But "make menuconfig" does not offer any rtai specific configuration options (or I totally missed if). Compiling the kernel works, but the rtai library does not think it's an rtai patched kernel.

Just comleted another test: Kernel compiles ok, but building rtai fails with this error message:

rtai-5.1/base/ipc/netrpc/user_softrtnet.c:23:26: fatal error: asm/rtai_srq.h: Datei oder Verzeichnis nicht gefunden
#include <asm/rtai_srq.h>

EDIT: found it. somehow a symlink in rtai-5.1/base/include from asm-x86 to asm is not created. Now rtai compiled successfully. But how to create a debian package from it?

EDIT #2: When I try to run any of the testapplication that rtai provides, the system immediately freezes. So I would not call this a success. Anyone that could put me on the right path on how to build a RTAI kernel that works?

You could try the linuxcnc IRC channel, if you are lucky then there is a chap who is often on there who is a bit on an RTAI expert.
