Alright, I got it so far that it now finds the DLL (seemed that I used the wrong Gecko SDK), however, The function call, which I now conveniently made to be "int getHelloWorld()" still doesn't seem to be fetched.
Also:
How can I dump a class and interface so that I now which methods are implemented?

Hi all,
I downloaded the latest gecko-sdk, which provided me with the most needed tools. I made a simple C++ implementation of a fairly simple "nsIHelloWorld" interface, only containing a "string GetHelloWorld()" method. This all goes well, see for code below.
All together it builds a DLL file called helloworld.dll and a .xpt file of the IDL interface. When pulling them into the components directory I run regxpcom to register both of them.
Now my components directory looks like:
components > ... helloworld.xpt helloworld.dll ... compreg.dat xpti.dat
This seems Okay. When digesting through the xpti.dat file, I clearly see that helloworld.xpt was found (yay), however, when looking into compreg.dat I can't find helloworld.dll.
My question: Where to put the helloworld.dll file, and how to register it properly, so it is usable with firefox/gecko.
Some extra information: firefox: release 1.0 (release version) os: windows (and linux, same problem)
