Calling LV created DLL from LV

Howdy-

I'm trying to call a LV DLL from within LV (seperate project).  Once the DLL has been comppiled I'm using the Import Shared Library to create the node.

However when I try this I get an error message with the import that appears to have trouble with LVBoolean and int32_t.

I've created a simple DLL (adds a DBL to an INT 32 and creates a Bool when the sum is > 0). 

Compiling this DLL and trying to import it has the same issue.

Any clues?
