Comment 1 Bernhard Rosenkraenzer 2009-01-30 14:43:27 UTC

Created attachment 30746 [details]
Fix

The attached patch fixes it -- not committing myself because this is so obvious that I'm probably overlooking something

Comment 2 Christian Ehrlicher 2009-02-20 15:07:50 UTC

looks like a too old soprano version - qHash(QUrl) was moved to soprano in 2.1.68 iirc

Comment 3 Christoph Feck 2009-06-24 06:50:44 UTC

The linker error clearly shows: the include files and the library files do not match. This is probably due to using headers from KDE, while libraries are from distribution packages.

Closing.
