[Kmymoney-devel] Re: Compile problem after KDE upgrade

[David Houlden]

Hi,

Problem solved and all my own fault. I had an old version of libphonon.so 
in /usr/lib/qt/lib with links in /usr/lib pointing to the old version. I 
think it was left over from an unofficial qt4 Slackware package which I 
built myself. I'm not sure why it didn't cause problems before but I have 
now cleaned up and I can compile and link again.

Very sorry for wasting your time on this but thanks for giving me the help 
to fix it.

Dave.
