errors while "bitbake opie-image" build

[Wenbin Zhang]

Hello, Guys,

I am using "bitbake opie-image" do OE compiling. But got lots of errors like
below. Someone suggested me add package "libqt4-dev", I added it, and in the
local.conf, my ASSUME_PROVIDED is set as ASSUME_PROVIDED += "libqt4-dev
qt4-native moc-native". But I still have these errors. Anyone has ideas?
Thanks!

The errors are:

Make sure you follow http://www.linuxtogo.org/gowiki/OpieWithAngstrom

  You probably should have asked them for reasons of such suggestion.

  Recently, gcc was upgraded to 4.1.2. There's always chance that it
broke C++ stuff again. I by now still didn't upgrade (just because I'm in
the middle of application-level hacking, and don't want land burn
under my feet). I'll try to check 4.1.2 during this week.

  For the future bug reports, using bug tracker, http://bugs.openembedded.org/

  Ok, so I rebuilt qte-mt, libopie2, and couple of apps using gcc
4.1.2, all works like a charm. So, just following instructions in URL
above should do the trick.
