Hello,

just updated to kde 4.2.1 and qt 4.5 on my slackware 12.2 laptop. The build fails with this error message:

I found this thread in the forum, but the patches for v2.0.1.1 and qt 4.5RC1 seem not to work for the new versions.

http://amarok.kde.org/forum/index.php/t ... 615.0.html

thx

There was a bug report about this issue quite some time ago:

https://bugs.kde.org/show_bug.cgi?id=177863

You need to apply the patch at the bottom of the thread:

https://bugs.kde.org/attachment.cgi?id=31715

If you need more help, please visit the #amarok IRC channel on Freenode.

I've done alot of testing on this. This is what I get

Using 4.5.0 from KDE Repos aka Qt-Copy
-----------------------------------------------
+Don't need the patch from the bugs.kde.org
- Introduces a new bug the QThreadPool

Using 4.5.0 from QtSoftware (official 4.5.0)
-----------------------------------------------
+ Doesn't introduce the QThreadPool bug
-You do need the patch

Amarok from svn
----------------------------------------------
If you are using the qt-copy it fails
If you are using the official 4.5.0 it will compile with the patch

Amarok 2.0.2
----------------------------------------------
If you are using the qt-copy (haven't tested)
If you are using the official 4.5.0 it won't compile do to patch failing to patch (atleast for me in Gentoo)

I am using qt-copy 4.5.0, patching the 2.0.2 release fails and the patched svn version fails to build with this error message:

That the patch works with the official qt release could be a good explanation for this, any ideas how to get it working on qt-copy?

It has something to do with one of kde's patches I presume. Just use the regular qt-4.5.0 there is nothing really different between qt-copy and the offical qt. just a few patches for KDE thats it
