Did anyone ever manage to build these sources? The only information about them I could find is lots of news from 2010 that "Symbian is now open source, yay".
I've talked to some people about it. Various members of the final teams to work on it are out there and occasionally comment.
I think it needs MS VC++, 32-bit, running on Win XP and nothing later, IIRC. But saying that, that should not be hard to obtain these days. The XP activation algorithm has been cracked; it's easy to build a working XP Pro VM now.
I suspect, but do not know, that there's a fair amount of legacy stuff in Symbian that could be junked now. Nobody is really going to care about backwards compatibility and compatibility with 20-year-old phone apps.
It had, what, 4-5 different UI layers available, I think?
* S60 for portrait touchscreen phones with a few physical buttons and a numeric keypad.
