Hi,
I'm trying to expose the Mailnews objects to CORBA. Since there's no
XPCOM<->CORBA mapping yet, I'm doing that manually.
Technically, I'm creating a server (the front-end will be the client),
so there's no UI at all wanted. So, I needed a minimal Mailnews app, not
a bootstrap via chrome and JS.
After a few hours of trying, I finally succeeded. Much luck involved :-)
(I was about to give up and just post for help). Looked into the
embedding (mozilla/embedding/) examples and also apprunner (woa, there's
a lot of cruft in the latter), since using only NS_InitEmbedding made
nsIAccountManager::GetDefaultAccount fail. I guessed that the profile
wasn't read, and I was right.
Anyways, the result is attached for your pleasure and guidiance, should
you want to implement something similar (e.g. embed Mailnews in another
app or implement a GTK frontend).
I intend contribute the resulting CORBA server to mozilla.org (under the
BSD license), assuming general applicability.
I'm happy to have won that fight! :)
P.S. mozilla/build/autoconf/make-makefiles creates the Makefile from
Makefile.in.
