Migrating Gecko 1.9 to 2.0 - Lot of errors - gecko

Question

OK, after migrated to Gecko 2.0 for my XPCOM Component,
I fixed a couple of thg like below:
1. Replacing #include "nsIGenericFactory.h" to #include "mozilla/ModuleUtils.h"
2. Replacing xpcomglue_s.lib to xpcomglue_s_nomozalloc.lib
3. Adding #include "mozilla-config.h" to xpcom-config.h header file
4. And as well as remove a couple of unused header file eg: nsReadableUtils.h, nsEventQueueUtils.h, nsIExtensionManager.h
5. Replacing NS_DEFINE_STATIC_IID_ACCESSOR(IMYPROGRAM_IID) to NS_DEFINE_STATIC_IID_ACCESSOR(IMyProgram, IMYPROGRAM_IID)
Reduced from 200+ errors to 20+ now, below are a few more errors which i have no idea what is that, any expert here encounter problem like below?

Answer 1

At the very least it looks as if you are missing an NS_DECLARE_STATIC_IID_ACCESSOR(IMYPROGRAM_IID) in your interface (xpidl would have generated that for you automatically.) Some of the other errors are a bit harder to figure out without source code, but the chances are that you haven't quite managed to update your module registration code correctly.
