You hit the nail on the head. Thankyou. It appears to be a missing typemap problem related to using __int64 in function args and return values.

The program uses two separate (.pm) modules that between them load XS code compiled into 5 different modules. One of the .pm modules loads a superclass and 3 subclasses. The error only occures when I make changes to one of the subclasses. That subclass fails to be found, but all the others work. If I delete their binaries, I see the error, but the non-offending subclasses work fine.

The problem is that the message doesn't tell you which module/package it has failed to build or produce functions for. Which in a program that builds multiple modules leaves you guessing, especially as the other modules will probably work.

The fix might be to change the message to include that information. Something like 

### Inline/C.pm(542)
warn("Warning. No Inline C functions bound to Perl ($data->{API}{modfn
+ame})\n".
##                                                 ^^^^^^^^^^^^^^^^^^^
+^^^^^
     "Check your C function definition(s) for Inline compatibility\n\n
+")
      if ((not defined$data->{functions}) and ($^W));

That's untested. $data->{API}{module} might be more appropriate. Or both?

Switching to doubles for passing the values in and out from/to Perl and converting internally appears to fix the problem, though there are other problems (mine!), with that subclass that mean I can't test it yet.
