Can't install user extensions? - SOLVED

[Robert S. Grimes]

Update - I did figure out how to build the tests, though I'm not sure it
was the correct way.  Anyway, sp07 works, so it was must be in my
configuration.  Well, maybe...

Stepping into RTEMS, I see _Extension_Allocate is calling
_Objects_Allocate, which fails early on.  Specifically, it fails on the
"if (information-size == 0 )" test - hopefully the comment means
something to the more knowledgeable folks?

     41    Objects_Control *_Objects_Allocate(
     42      Objects_Information *information
     43    )
-    44    {
     45      Objects_Control *the_object;
     46   
     47      /*
     48       *  If the application is using the optional manager stubs and
     49       *  still attempts to create the object, the information block
     50       *  should be all zeroed out because it is in the BSS.  So
let's
     51       *  check that code for this manager is even present.
     52       */
-    53      if ( information->size == 0 )
     54        return NULL;

Well, this comment gave me a clue - a missing manager?!  In my Makefile,
I had this:

    MANAGERS=io event message semaphore

Seeing as it isn't clear to me which one is missing, I changed it to this

    MANAGER=all

Now it works!

Anyone have any strong reasons for not just sticking with 'all'?  (I
have *lots* of memory).  If so, where is there a convenient list of the
managers, their names, and how to determine which ones to include?  I'm
sure it's all there somewhere, but is it tied together anywhere?

Thanks,
-Bob
