PJOBs won't build with 15.3.0 - DECLARE_JOB: too few arguments

Hi all,

I'm running into trouble with the latest XTC Tools 15.3.0 release. Whenever I include

<xcore/parallel.h>

in a C/C++ file, with the purpose of running tasks in parallel within the same tile, I run into this error:

Code: Select all

The job is declared (hopefully correctly?) as:

Code: Select all

#ifndef __I2S_HPP__
#define __I2S_HPP__

extern "C" {
    #include <xcore/parallel.h>

    DECLARE_JOB(i2s_task, ());
}


#endif  // __I2S_HPP__

...in a header that I then include in the file implementing the main task for that tile.

Building with XTC 15.2.1 gets rid of the problem! But I lose all the functionality that I need with 15.3.0 (e.g. better xgdb, included cmake).

I raised a ticket on the XMOS official website with the issue, but haven't got any feedback yet. Would anyone be able to reproduce the issue? Many things (including examples in xcore_iot) won't build with 15.3.0 for me, due to this error. Any pointer much appreciated. Thanks!
