[cfe-dev] Compile errors when building kde-runtime

[Rolf Eike Beer]

Hi all,

a few minutes ago one KDE developer reported that he was not able to
compile kde-runtime (git clone git://anongit.kde.org/kde-runtime) using
clang version 3.1 (http://llvm.org/git/clang.git
f196a90b26479a2c67959c6715491763cbc8ade1) and Qt 4.8. The errors have been
fixed in revision ac48ea95. At least the first ones (the (QHash<>) stuff)
seems to be present for a while, I see a commit 7 month ago that
introduced them to fix build using llvm-gcc on Apple.

I'm not involved in either LLVM nor Nepomuk stuff in any way, but I
thought you might be interested. I'm not on this list, so please keep me
in CC if you have any interesting insight. It may of course be that the
code was wrong, in this case we of course would like to know why.

I'll post the first parts of the errors below, there are lot of
duplications and later errors because of the first problems so I cut them
down.

Greetings,

Eike
