Qt is horrible to package, but if I recall qtopia.spec deals with a similar

Yes indeed, Qt is a horrible package ;)
I don't think the situation is similar to qtopia though, since the
tools built by Qt are needed by all subsequent packages that use Qt.
This means I need to put them somewhere on the $PATH (I settled for
${TOP}/bin), and I also need to install a few data files needed by
those tools (I settled for ${TOP}/bin here too). It seems to work all
right, but it's far from elegant.
Am I correct in my assessment that this scenario is rather poorly
supported by ltib (and probably every other rootfs builder out there
too)?

Hi Magnus,
It's worth taking a look, I believe qtopia used to build a whole pile of
host packages and cache/stuff them in the users' home directory (? can't
remember) so that subsequent builts etc could use them (for example moc
and friends). I think the build systems are similar. Might be a few clues.
Your approach is reasonable. There's not magic bullet here
unfortunately as you have to trade off whether the tools you built can
be shared across projects (lets say you have another BSP that has a
different set of options/versions of the same tools). This will drive
where you save these.
I'm not sure about other rootfs builders. For ltib, the approach for
host support packages is to build them and put them under /opt/ltib as
rpm packages, controlled by their own private rpm database. So you
could create a qt-host-package.spec file and build this and install it
as an ltib host support package (check out ./ltib --hostcf). Doing this
would mean it would be common for everyone on that host, which may or
maynot be okay for you.
Regards, Stuart
