Hello,

Thanks for the suggestion. It didn't quite work but what I've found is that some arinc653 functions behave like this and others don't e.g. the arinc653/partition are call-able. I still haven't quite found what's the difference between the partition calls and the blackboard calls so that the blackboard calls are not able to be called.

Apart from the POK_NEEDS and POK_CONFIG defines, are there any other configurations that I'm overlooking?

Thanks,
Janek

Hello everybody,

I'm not expert in POK (I've just looked at it, but still didn't find the time to really try it), but I'm familiar with C and compile-time customization, and I think your problems comes from the fact that you define your POK_CONFIG_* and POK_NEEDS_* configuration constant AFTER including POK header files. Try to define it BEFORE #includes, it should compile better.

The usual way for such configuration defines is to put them all in a single file (named "pok_config.h" for example), and to include it before any other header file.

So you'll have a pok_config.h file that says:

#define POK_CONFIG_NB_BLACKBOARDS 1
#define POK_NEEDS_BLACKBOARDS 1
#define POK_NEEDS_MIDDLEWARE 1
#define POK_NEEDS_ARINC653_BLACKBOARDS 1

And your send.c file will start with:

#include "pok_config.h"
#include <types.h>
#include <libc/stdio.h>
#include <arinc653/blackboard.h>
#include <arinc653/types.h>

It should compile better.

Re: [pok-devel] Userspace arinc653 calls

That might indeed explain it better, so I have now added the current files I use for my tests as attachment. I'm also well aware that the user_send function gets called every 1s as configured in the model..aadl but since my priority is getting the project to compile I don't think it matters that much.

Thanks,
Janek
