Error using POSIX mqueues on Arduino Rev 2 LEDEYun 17.11?

[amcbain-arduino]

Hello, I have an application written in c that I am attempting to run on my Arduino Rev 2's microproccessor. I have been cross-compiling using this buildroot (GitHub - arduino/lede-yun) and have successfully gotten most of my code running, however I seem to have an error when I attempt to utilize the mqueue library on the yun. Here is the example code.

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <errno.h>
#include <mqueue.h>
#include <stdio.h> 
#include <string.h> 
#include <stdlib.h>

#include <fcntl.h>

#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;
}

I can get it compiled just fine but once I scp it to the yun I get this error from mq_open()

main:33: (mqd_t)-1 != mq: Function not implemented

Is there a way to configure or patch this? I am concerned with getting a totally new image on the yun since I want to utilize the integrated serial connection between the Yun's AVR chip and the microprocessor so I can send data from the AVR side to the microprocessor OpenWrt is on.

Thanks in advance for any assistance.
