It seems that the original problem ("undefined reference to `CheckExtensionImpl") is that CheckExtensionImpl symbol is not exported in taglib-extras.
Upgrading to taglib-extra-1.0.1 fixed a problem for me.

How to compile taglib with asf support in kdesvn-build? I use KDE trunk compiled with it everyday and need Amarok trunk.

Open Konsole and change into the build/kdesupport/taglib directory. Then run "cmake . -DWITH_ASF=TRUE then you can run kdesvn-build as normal and ASF support will be included.

You could also have read the previous posts where you could have found the answer...

Code: Select all

[kde-devel@ban-desktop taglib]$ cmake . -DWITH_ASF=TRUE
CMake Error: The source directory "/home/kde-devel/kdesvn/build/kdesupport/taglib" does not appear to contain CMakeLists.txt.

When I use this command in ../kdesvn/kdesupport/taglib/, taglib compile against without asf support...

Try

Code: Select all

cmake .. -DWITH_ASF=TRUE

Hmmm, cmake works... Log:

Unfortunately taglib still haven't asf support.
It seems to me, that kdesvn-build overwrite my cmake config.

Well, you need to compile taglib with the support enabled, then erase your previous CMakeCache, else it will still search for the old taglib packages. But all this is already described in the previous posts in tis thread, please search back...

I deleted old cmakefiles...
I use KDE from kdesvn-build and must compile taglib with asf in kdesvn-build, but I can't.

All of solutions in this topic doesn't work....

Try this

Code: Select all

cmake /path/to/kdesupport/build -DWITH_ASF=ON -DWITH_MP4=ON

Hi, I've tried to recompile kdesupport with this parameters, but amarok still tell me that asf support is not enabled.

On my kde directory I've those files:
./include/taglib-extras/mp4tag.h
./include/taglib/mp4tag.h

Make sure that you don't have multiple versions of Taglib installed.

Alreay checked

Have you set $CMAKE_PREFIX_PATH to include the KDESupport installation directory?

Example - I install KDE to /opt/trunk-kde/kde and Qt to /opt/trunk-kde/qt

Code: Select all

CMAKE_PREFIX_PATH=/opt/trunk-kde/kde:/opt/trunk-kde/qt

bcooksley wrote:Have you set $CMAKE_PREFIX_PATH to include the KDESupport installation directory?

Of course, I've a similar path, so both $CMAKE_INSTALL_PREFIX and $CMAKE_PREFIX_PATH are set to my custom path. Maybe i'm doing something wrong with cmake. This is the command i execute:

Code: Select all

cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` -DCMAKE_BUILD_TYPE=Debug -DWITH_LibLastFm=OFF -DWITH_MP3Tunes=OFF -DWITH_Mtp=ON -DWITH_Ipod=OFF -DWITH_Strigi=OFF -DCMAKE_PREFIX_PATH=`kde4-config --prefix`


I've added the last -DCMAKE_PREFIX_PATH=`kde4-config --prefix` after your suggestion, before it simply was an enviroment variable, but nothing changed. This is the output of cmake:

Code: Select all
