Thomas,
I think the second script is failing because you are not actually giving any
C++ code
to Inline::C++.
If you put your code either __DATA__ or __END__, you have to use
use Inline CPP => DATA
This is what tells Inline::C++ to get the code from __DATA__ or __END__
For the first script, run nm on the library that actually defines the
constructor for Cccm_srdfaIpc
and see if the signatures match exactly. What is the prototype for that
constructor?
Cheers,
Parick

Subject: nm finds the symbol, but perl does not...is the silence in here
deafening, or is it just me?
