Re: [paho-dev] Using Paho C client on OS X/iOS?

Andy,

the short answer is no.  The samples I originally wrote were not the ones used by MQ, which were written by someone else.  And they have a few issues.  Once I am clear that I am allowed (IBM legally) to compile on Mac OS X, I'll have a go at sorting that out.

In the meantime, I'll try to find the time to sort out the samples, or add my own preferred ones.

Has anyone successfully compiled the Paho C client on OS X *and used it in an application*? It may be a problem between chair and keyboard and the weirdness of trying to make sense of Xcode… I think I have a static library built, but I'm having trouble building the samples (the ones buried in the doxygen docs… it would be nice to get those put into the repo in regular source form, btw).

For example I'm seeing (for the async sub client):

subclient.c:21:13: error: 'void' must be the first and only parameter if specified
int msgarrvd(void context, char *topicName, int topicLen, MQTTClient_message *message)

    payloadptr = message->payload;

subclient.c:33:17: error: indirection requires pointer operand ('int' invalid)
        putchar(*payloadptr++);
