Re: Build problems with qt

[Evan Huus <eapache () gmail com>]

Some of these errors look a bit like the ones I've been fighting,
where the moc and uic binaries are Qt4 but the main include paths are
Qt5 (I also had the opposite problem briefly: moc and uic were Qt5 but
the main include paths were Qt4).

It may be worth checking what paths and versions all of those are to
make sure they line up.
