Hi everyone
I try to compile the weather plasmoid which is in kdereview now. Unfortunately there are two problems. The first is related to CMakeLists.txt:

Code: Select all

david@farnsworth ~/build/kde4/weather % cmake CMAKE_INSTALL_PREFIX=/usr .
-- The C compiler identification is GNU                                 
-- The CXX compiler identification is GNU

-- Check for working C compiler: /usr/bin/gcc -- works                   
-- Detecting C compiler ABI info

-- Check for working CXX compiler: /usr/bin/c++ -- works                 
-- Detecting CXX compiler ABI info                                       
-- Detecting CXX compiler ABI info - done
CMake Error at CMakeLists.txt:8 (kde4_add_ui_files):
  Unknown CMake command "kde4_add_ui_files"

That happens with a couple of plasmoids I tried from svn repositories. Usually I was able to solve it by inserting the following in CMakeLists.txt:

Code: Select all

# Find the required Libaries
find_package(KDE4 REQUIRED)
include(KDE4Defaults)

Why does it happen with so many plasmoids?
The second problem is that the weather plasmoid does not compile here. Since it is in kdereview I excpected it to be easier.
Here is what I get. It is especially strange since nothing else (qt4/kde4 related) had an error like this.

It goes on like this but shows alway the same messages.
I use Archlinux with kde4 trunk (4.1.86) and qt 4.4.3. Maybe there is an other variable missing from CMakeLists.txt. Do you have any idea how to fix this?
Thanks,
David

Hope you don't mind if I just copy and paste some IRC logs: somebody asked exactly the same question earlier today

Code: Select all

11:29]  i tried to compile the new weather plasmoid in kdereview, but it keeps telling me :
[11:29]  ian| has joined this channel (n=ian@dslb-088-077-083-051.pools.arcor-ip.net).
[11:30]  unown cmake command "kde4_add_ui_files"
[11:31]  so i added "lfind_package(KDE4 REQUIRED)" to the cmake file
[11:31]  no
[11:31]  ademmer: You need to checkout all of kdereview and run cmake from the top level of that, if you haven't done so.
[11:31]  you have to run cmake (that does not mean "compiling all") from the top-level of kdereview
[11:31]  ademmer: Then you can compile and install individual components.
[11:31]  pinotree: ah, i see, I'll try

...


[11:34]  pinotree, SSJ_GZ: that worked quite well! could anyone give a very short explanation why i need to check out a whole dir? i'd like to understand wthe reasons for this
[11:34] --> Scorcerer has joined this channel (n=Scorek@77.87.120.128).
[11:34] * SSJ_GZ defers to pinotree :)
[11:35]  ademmer: kde never supported bulding random subpieces of a module
[11:36]  pinotree: i am new to kde development but i will definetely dig into this
[11:36]  you configure from the top level (that does NOT mean having the whole stuff, you can checkout pieces in a smart way), and then `make` in the subdirectories you want
[11:36]  thx for helping, plasmoid's up and running

Thanks, that explains it. It is a bit of mess now but cmake works now.
Unfortunately it still does not compile. Now I get this:

You'll need kdelibs trunk from within the last 7 days.

Thanks, I try to updadate. Didn't expect that.

Code: Select all

 you configure from the top level (that does NOT mean having the whole stuff, you can checkout pieces in a smart way), and then `make` in the subdirectories you want


By the way, the smart way pino is talking about is to use svn co -N kdereview, then svn up plasmoidname, then cmake in the kdereview directory, then make. That will build only the plasmoid.

Thanks for the info. But how am I supposed to do that with plasmoids in playground? Where should I start there. For example when I checkout the plasmoid base folder I get plenty of errors because of missing subdirectories. But I don't think I need for example the "stockwidget" plasmoid when I want to compile something else.

With Playground, a quick hack would be to edit the CMakeLists.txt file in the plasmoids directory and comment out ( "#" ) the ones which cause errors.

Ah I see. I tried that and configuring works, thanks. networkmanager is still not compiling but that's an other story.

EDIT: Just looked at the network manager applet plasmoid thread....
