Subject: Re: posix_mq : Problem installing on HPUX

More info ...

I commented the offending code (see below) and the compile worked.
But now when I run the command line utility
MQUEUE=/testq.acore posix-mq-rb create
the queue is created, but the program crashes with

/usr/lib/dld.sl: Unresolved symbol: MQ_IO_NIL_P (code) from
.../posix_mq_ext.sl

nm posix_mq_ext.sl | grep MQ_IO_NIL  # gives =>
MQ_IO_NIL_P   |      |undef |code |
MQ_IO_NIL_P   | 12976|uext  |stub |
Which tells me that the symbol exists.
So I haven't a clue as to what is going on.
Any ideas ??

Tad


static VALUE _close(VALUE self)
{
        struct posix_mq *mq = get(self, 1);

/* The if statement doesn't compile - error 1558: The ! operator takes a

        if ( ! MQ_IO_CLOSE(mq) ) {        /* line 712 */
                if (mq_close(mq->des) == -1)
                        rb_sys_fail("mq_close");
        }
*/
        mq->des = MQD_INVALID;

        return Qnil;
}
