Am I missing something, or should extern(C++) just work for binding to gcc C++ on Linux.  It works fine for primitives but fails for pointer type arguments.  Extern "C" works fine.

Does D know how to mangle function names based on pointer types? I have created matching types on both sides.

Though I am using typedefs.  Eg struct Foo_; typedef struct Foo_ Foo; and on D side struct Foo {}

Could that be why?

What the best way to see the types of library file function arguments for a libfoo.a file on Linux?   Sorry for the dumb question.

Thanks.

Yes. C++'s typedefs and using are just like D's alias. The underlying type is used in the mangling.
