I\'m compiling amaroK from source some time, and newer had any problems. Now, when I\'m trying to make 1.3.5 I\'m getting the following errors:
Some time ago I made an apt-get dist-upgrade, bo everything was fine... What is wrong? What should I do? |

Try grabbing the latest source from SVN and recompiling. It should be fixed now (thanks to eean).

Is a problem with glibc. If you don\'t want to run TRUNK, here is a patch that should apply cleanly to 1.3.5 that should fix this.

Thanks very much for the patch. It did the work
I can\'t run the svn version, becouse I have not fully configured svn. Have to sit and work about it

The same error returns in 1.3.6
I read the comments in bug report [url=\"http://bugs.kde.org/show_bug.cgi?id=115068\"]BR115068[/url], and these solutions don\'t work. Distro: PCLinuxOS $ rpm -q glibc glibc-2.3.2-14mdk $ uname -r 2.6.12-oci5.mdk Hope, this info will help solve this problem

same exact prob. running PCLinuxOS 2005. I wanted to install from source since it seems the the pclos package dosen\'t have the mysql support. I WANT MY AMAROK WITH ALL THE GREAT FEATURES!!!!
thanks :whistle: |

OK, I\'ve just backported our fixes for that to 1.3-branch. That means 1.3.7 is going to compile on PCLinuxOS. A word of warning though: The HyperThreading fix will then not work on PCLinuxOS. If you got a P4, you will have to disable HyperThreading, or suffer from amaroK crashing.
