  • Include file math_neon.h missing

that should copy the ne10/ folder as well. What is the #include line that fails, exactly? In what file? If it is
#include <ne10/NE10.h>, it should work!

My bad. The script file wasn't getting saved out because of permissions. Now I don't have include file errors, but I do have the error below and a bunch more just like it. I just pulled from the dev branch.

In file included from ../core/AuxTaskRT.cpp:3:0:
../core/../include/xenomai_wraps.h: In function 'int create_and_start_thread(pthread_t*, const char*, int, int, void* (*)(void*), void*)':

  __wrap_pthread_setname_np(*task, taskName);

Right. I think that the order of the -I parameters is wrong. You should have -I"/usr/local/linaro/BelaSysroot/usr/xenomai/include" second, just after -I"/Users/Andy/Dropbox/Developer/Bela/include". I think in Eclipse you fix this by changing the order of the include path in the C++ build settings, but I haven't used Eclipse in ages.

Doesn't seem to help:

BTW, what do you use instead of Eclipse? I'm always keeping my eye out for something better.

    can you post the output of

    ls /usr/local/linaro/BelaSysroot/usr/xenomai/include

    ?
    Incidentally, you can probably workaround that by adding
    int __wrap_pthread_setname_np ( pthread_t thread, const char * name );
    at the top of xenomai_wraps.h, but I am more curious about the underlying issue.

    jandyman BTW, what do you use instead of Eclipse?

    For Bela, I just compile on the board.

        giuliomoro ncidentally, you can probably workaround that by adding
        int __wrap_pthread_setname_np ( pthread_t thread, const char * name );
        at the top of xenomai_wraps.h, but I am more curious about the underlying issue.

        Actually, in hindsight, both the changes suggested above should not make any difference, because the declaration is there already, though conditional to #if XENOMAI_MAJOR == 3. So the problem seems to be that -DXENOMAI_MAJOR=3 is - for some reason - not reaching the file?
        Can you try adding these lines at the top of include/xenomai_wraps.h?

        #if XENOMAI_MAJOR == 3
#error XENOMAI_MAJOR is in fact equal 3
#endif

#ifdef XENOMAI_MAJOR
#error XENOMAI_MAJOR is defined but not equal 3
#endif

          I’m guessing the changes I made to the bela project have gone missing somehow, this all looks like compile and probably linker settings are incorrect in the project.

          I’m back on the 4th and will have a look then...

          I just looked at the dev, master and dev-modular branches and XENOMAI_MAJOR is set to 3 in all of them .

          @jandyman if you go to the c and c++ defines section of the project do you see it there?

          Don’t worry, I can see it in the GCC command line you sent, something must be undefineing it?

          That is meant to be 3 on al v0.3 and above images (all images since October 2017).

            Sounds like @AndyCap has answered @giuliomoro 's question, and the current issue is what might be redefining it. I can wait until the 4th for this to be unraveled.

            In the meantime, I'm hoping to make some progress on the issue of wireless control of DSP running on Bela, over BLE or Wifi. I'm surprised it isn't a more popular subject and a path more travelled. The need seems obvious. I'm willing to do some trailblazing, especially in terms of developing a useful protocol on top of a raw byte or text stream, but I'm not a Linux expert so I'm afraid of falling into a black hole getting a basic link working.

            Look at “open sound control” for the controller side. There are some Bela code examples.

            giuliomoro That is meant to be 3 on al v0.3 and above images (all images since October 2017).

            Just looked at the code, the error will only appear if XENOMAI_MAJOR == 3 so the problem isn’t there, what seems to be strange is that there is no forward declaration of __wrap_pthread_setname_np at the top of Xenomai_wraps.h the others seem to be there.

            It’s a bit hard to work out on an iphone!

              Right.

              I got confused a couple of times in this thread, sorry about that, but I think that the initial intuition was right. The problem here seems to be that the Xenomai includes are not picked up.
              Can you try to run the following

                  ls /usr/local/linaro/BelaSysroot/usr/xenomai/include

              on your computer?

              Andys-MacBook-Pro-3:~ Andy$ ls /usr/local/linaro/BelaSysroot/usr/xenomai/include
alchemy		cobalt		psos		smokey		vxworks		xenomai
boilerplate	copperplate	rtdm		trank		xeno_config.h

                Re Open Sound Control. That would work, but has anyone got a wireless link running on Bela
                to operate it over?

                  jandyman right

                  i think you need to add

                  /usr/local/linaro/BelaSysroot/usr/xenomai/include/cobalt

                  To your include paths

                    It was actually in the include path, just further down. Moving it fixed that problem, now we have missing libraries:
