So if you don't want to go through the hassle of check= ing it out from Git, you could simply delete that one line in the source co= de, as indicated by Heiko's linked patch.

Sorry for = the trouble :)

Unfortunately not, but it's already fixed in the 2.9 branch:
htt= ps://cgit.kde.org/amarok.git/commit/?h=3D2.9&id=3Df047cd8219d= 9537bb33bba3883bedf6231a0ed5f
(Or you can switch to gcc7).
