Fwd: Re: compile error qt-dbus

[David Faure]

Any reason why there would be no rpath on binaries for this person?
cmake version 2.4-patch 2
This is about kdesupport/qt-dbus, so there isn't any kde customizations of the rpath stuff
happening there.
The binary is run during compilation, but doesn't find the library it links to (which is in the builddir).
Since it works for me, I'm guessing there's some cmake behavior difference somewhere...

This a Gentoo/Linux system

after a make clean && make (that fails at the examples)

 $ readelf -d tools/dbusidl2cpp | grep RPATH

There doesn't seem to be an RPATH defined in the binary...
