[oe] GCC Error

[David Thomas]

Well not everyone works this day in and day out now do they? Show me where it states you have to use gcc.4.6 and for that matter, I specifically choose a LTS platform to avoid having to play latest and greatest.

So I ask, what is gained by forcing the user to have to use the absolute latest version?

In addition, it is not necessarily clear to a OE newby how all this is pieced together? It is a hackers paradise, I am not a hacker, I have a schedule to meet.
Perhaps 

In any event, it is moot, were dumping the cm-t35 and using a beagleboard for product demonstration as it is a dead end. 

"The toolchain problems wouldn't have been there if people had used an existing, working distro like angstrom, the kernel issues mentioned above are all handled automagically by linux.inc."

Really?
