Just upgraded to Ubuntu 17.10 and while I could build amarok on 17.04 I now get the following error

The only reference to this I found was https://bugzilla.redhat.com/show_bug.cgi?id=1396755 but that doesn't help.

As a workaround I ran cmake with

-DWITH_MP3Tunes=OFF

and now have a working version (again)

This is most likely caused by Qt4's moc beging stupid and failing to understand macros in combination with glibc >= 2.25.

You can patch your qt (or make your distro aware off ) with something like that: https://git.exherbo.org/kde.git/tree/pa ... 2829.patch (The "pp.macros["_SYS_SYSMACROS_H_OUTER"];" line is the important one in this case). https://bugzilla.redhat.com/show_bug.cgi?id=1396755 has more information.

@heirecka how can you patch your qt4 ?

When I run "qmake --version" I get:

--------
QMake version 2.01a
Using Qt version 4.8.7 in /usr/lib/x86_64-linux-gnu
--------

However, I can't find the file "src/tools/moc/main.cpp" specified in your link https://git.exherbo.org/kde.git/tree/pa%20...%202829.patch in order to make the modifications.

Do I need to re-install qt4 from source to be able to modify that cpp file?
