Hello Ran,
If you modified something in Makefile, others starter people would
thanks you to know.
Else, if interested, here you will find a little simple example of a
periodic task,
working both with Xenomai 2 and 3, using Posix API (and not native one).
So that the same source code can also be compiled for 'standard' Linux,
really usefull !

Best regards.

Hello,
I have installed xenomai 3.3 with kernel 4.1 ,ubuntu 14.04 and it all
seems to work very well, resulting in good performace ~20u ,tested
with cyclictest and latency. (I just has some issue with install,
"debuild -uc -us" , seems not to created /usr/xenomai/demo, so I
installed again with "make install")
Now, I then tried to build a very simlpe application.
Is there a simple code sample with Makefile for xenomai 3 demonstration ?
I did find the following link with example:
http://www.acadis.org/pages/captain.at/timer-task
So I tried it but it gives errors:
1. it first gave the following errors:
"...fatal error: native/task.h: No such file or directory"
so I changed from:
#include <native/task.h>
to:
#include <trank/native/task.h>
Is it correct ? Or should I use <alchemy/task.h> instead ?
2. I also had to remove <trank/native/intr.h> bevause there is no such file.
3. Then I got link errors:
user@user-desktop:~/rt/xen/myapp$ make

The make options seems to include the required library , so I am not
sure why I get these link errors.
This is the makefile:
=======
XENO_CONFIG := /usr/xenomai/bin/xeno-config
CFLAGS := $(shell $(XENO_CONFIG) --vxworks --cflags)
LDFLAGS := $(shell $(XENO_CONFIG) --vxworks --ldflags)
CC := $(shell $(XENO_CONFIG) --cc)
EXECUTABLE := test
all: $(EXECUTABLE)
%: %.c
$(CC) -o $@ $< $(CFLAGS) $(LDFLAGS)
======
Regards,
Ran
