Hi Sven,
It's not really your fault, the problem is the current name collision
problem with rtai_lxrt.h (between lxrt and lxrt-informed), this will be
fixed when the versions get aligned. If you are using the user_hrt.c
example in the lxrt directory, you will see that it includes
../rtai_lxrt.h, this is because it has to include that file and not the
one found <rtai>/include. If you are trying to build this example in a
directory other than lxrt (did you copy it somewhere else ??) you will
need to remove the ../ prefix in the include (make it #include
<rtai_lxrt.h> and then change your make file as shown below:
INCLUDE = -I$(LINUX_HOME)/include -I$(RTAI_HOME)/lxrt
-I$(RTAI_HOME)/include
Hope this fixes it for you
Regards, Stuart
