Attached to Project - OpenWrt/LEDE Project
Summary - Error using POSIX mqueue on Arduino Yun Rev 2 LEDEyun 17.11
Task Type - Bug Report
Category - Kernel
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - All
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
 - Device problem occurs on: Arduino Yun Rev 2 (Atheros ar9331, mips architecture)

 - Software versions of OpenWrt/LEDE release, packages, etc.: Used this buildroot to cross-compile for LEDEYun 17.11 https://github.com/arduino/lede-yun

 - Steps to reproduce: Able to successfully compile c code that uses POSIX mqueue with above buildroot and toolchain, however after copying the executable over to the Yun I get thrown an error:
   "main:33: (mqd_t)-1 != mq: Function not implemented"

Example code that uses POSIX mqueue and throws the error when running on the yun:

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include  
#include  
#include 

#include 

#include "common.h"

int main(int argc, char **argv)
{
    mqd_t mq;
    struct mq_attr attr;
    char buffer[MAX_SIZE + 1];
    int must_stop = 0;

    /* initialize the queue attributes */
    attr.mq_flags = 0;
    attr.mq_maxmsg = 10;
    attr.mq_msgsize = MAX_SIZE;
    attr.mq_curmsgs = 0;

    /* create the message queue */
    mq = mq_open(QUEUE_NAME, O_CREAT | O_RDONLY, 0644, &attr);
    CHECK((mqd_t)-1 != mq);

    do {
        ssize_t bytes_read;

        /* receive the message */
        bytes_read = mq_receive(mq, buffer, MAX_SIZE, NULL);
        CHECK(bytes_read >= 0);

        buffer[bytes_read] = '\0';
        if (! strncmp(buffer, MSG_STOP, strlen(MSG_STOP)))
        {
            must_stop = 1;
        }
        else
        {
            printf("Received: %s\n", buffer);
        }
    } while (!must_stop);

    /* cleanup */
    CHECK((mqd_t)-1 != mq_close(mq));
    CHECK((mqd_t)-1 != mq_unlink(QUEUE_NAME));

    return 0;
}
