Hello

I use openSUSE 11.0 and KDE 4.2.0. I'd like to compile plasma-weather but I get an error when I run make. I assume that I miss a devel package but how, if so, do I find out which I miss?

CMakeFiles/plasma_applet_weather.dir/plasma-weather.o: In function `Plasma_Weather::parseData()':
/home/michael/Downloads/weather/plasma-weather.cpp:106: undefined reference to `QDomDocument::QDomDocument(QString const&)'

Thanks a lot

Undefined references usually indicate that it is not linking aganist something. I assume you mean the weather Plasmoid located in extragear/base/plasma/applets/weather. If so, it built, linked and installed fine for me.

QDomDocument is part of the QtXml module of the Qt toolkit. There should be no problems building.

Thanks

guess I need to stopp this here (at least for me). I have not found the mentioned QT packages with openSUSE an I really run out of time.

THanks for the help!
-bushveld

QtXml is usually part of the normal Qt package. Please try with a clean build directory and the latest updated packages.

Hi,,

here a liittle different bug after an update to the latest KDE 4.2.0 rel 83.1...
But still no luck... I have no idea what I can do at this point..

thanks again

Could you run make like this, and post the output here?

Code: Select all

VERBOSE=1 make

Sure,
hope you find more infos

Here is the line where the problem starts IHMO....

Great,

now the make works but the checkinstall make install fails with a similar problem.
I have not understood what the above mention hint from you does but it worked for make.

thx

Hi,

finally something I can provide instead of just asking for help...

For some reason it doesn't seem to link to the Qt XML library.
So I added ${QT_QTXML_LIBRARY} to the target_link_libraries section of the CMakeLists.txt file and it works fine!

Thanks to all
-bushveld

You may wish to inform the developer(s) of this Plasma widget so they can fix it upstream.

Allready done

-bushveld

Could you please mark the thread as solved? Thanks in advance.

Hi,

this is the second time I solve a thread and it is not marked....
Will now unsovle it and solve it again...
