[maemo-developers] osso_initialize: how to make it work?

[From: maemo.mexon at spamgourmet.com]

I've been scouring the documentation on maemo.org and getting pretty 
frustrated.  Almost none of it is up to date, and almost none of it is 
relevant to a beginning developer.  So:

Here is my code:

#include <stdio.h>
#include <libosso.h>

int main(int argc, char* argv[])
{
     osso_context_t* osso;

     osso = osso_initialize("name.exon.mapcacher", "20100529", TRUE,  NULL);
     if (!osso)
     {
         printf("Failed to initialise osso\n");
         return 1;
     }

     return 0;
}

Here is the output:

Failed to initialise osso

Why?

Also, what does "osso" mean?  Years of using Maemo, I've never figured 
that out.

Is there any genuine getting started tutorial showing how to write a 
program that actually works in Maemo?  Is there a hello world 
application that's less than a hundred lines, with an explanation of 
what all those lines are for?
