macOS shmget() and shmat() problem

[acidity]

Hello

I am trying to compile http://www.dbmail.org/ on my MacBook. I have successfuly compiled it on FreeBSD and Ubuntu so it should work on Mac OS X too.

One of the file has the following code:

void scoreboard_new(serverConfig_t * conf)
{
    int serr;
    if ((shmid = shmget(IPC_PRIVATE,
            (sizeof(child_state_t) * HARD_MAX_CHILDREN),
            0644 | IPC_CREAT)) == -1) {
        serr = errno;
        TRACE(TRACE_FATAL, "shmget failed [%s]",
                strerror(serr));
    }   
    scoreboard = shmat(shmid, (void *) 0, 0); 
    serr=errno;
    if (scoreboard == (Scoreboard_t *) (-1)) {
        TRACE(TRACE_FATAL, "scoreboard init failed [%s]",
              strerror(serr));
        scoreboard_delete();
    }   
    scoreboard_lock_new();
    scoreboard->conf = conf;
    scoreboard_setup();
    scoreboard_conf_check();

    /* Make sure that we clean up our shared memory segments when we exit
     * normally (i.e. not by kill -9, if you do that, you get to clean this
     * up yourself!)
     * */
    atexit(scoreboard_delete); }

The code compiles correctly but shmget() and shmat() fails with error:

shmget failed [No space left on device]
scoreboard init failed [Permission denied]

I tried to follow the steps given at http://www.spy-hill.net/help/apple/SharedMemory.html to solve the shmget() issue but without success. For the second issue, I found:

http://developer.apple.com/technotes/tn2002/tn2053.html

A problem where shmat would fail with a permission denied error when it was attempted by root has been corrected. (r. 2910913).

but apparently it still fails on my Mac OS X Tiger.

Any ideas?
