Hello,

I would like to have shiny RSS plasmoid - RSSNOW (it comes from kdereview right now). I have compiled it without complications (on Gentoo with KDE 4.1.2), but it is "Fetching feeds" and nothing happened.

In .xsession-errors I see:

Code: Select all

 plasma(23104) News::connectToEngine: Connect to source: "http://planetkde.org/rss20.xml"


Anyone knows how to force it to fetch some feeds? I saw on this cast it is possible

Do you have the "rss" dataengine installed? Without it RSSNOW is going to just be a pretty paper weight.

How could I check if I have it?

Open krunner ( Alt + F2 ) or konsole, and type plasmaengineexplorer.
A dialog should come up with a dropdown. look under that dropdown for "rss". I don't have it installed, but then again i don't have an RSS plasmoids installed.

OK, thank you for this tip. Now I know direct reason - lack of rss dataengine.

Next step/question is: how to compile rss dataengine from trunk into kde 4.1.2 installation (if it is possible)?

btw. nice technical documentation about dataengines could be found here.

The rss DataEngine is now in kdebase/workspace/plasma/dataengines/ in trunk. You could grab just that directory, add something like this to the CMakeLists.txt:

find_package(KDE4 REQUIRED)
include (KDE4Defaults)
include (MacroLibrary)
include(MacroOptionalAddSubdirectory)
include(MacroOptionalDependPackage)

and build it as a standalone.

Thank you, Aaron. I have added also this to CMakeLists.txt:

Code: Select all

include_directories(
   ${CMAKE_SOURCE_DIR}
   ${CMAKE_BINARY_DIR}
   ${KDE4_INCLUDES}
   )


But, it won't compile:

Code: Select all

Linking CXX shared module lib/plasma_engine_rss.so
CMakeFiles/plasma_engine_rss.dir/rss.o: In function `RssEngine::updateSourceEvent(QString const&)':
/soft/dataengines/rss/rss.cpp:89: undefined reference to `Syndication::Loader::create()'
/soft/dataengines/rss/rss.cpp:99: undefined reference to `Syndication::Loader::loadFrom(KUrl const&)'

make[2]: *** [lib/plasma_engine_rss.so] Error 1
make[1]: *** [CMakeFiles/plasma_engine_rss.dir/all] Error 2

Maybe there were some changes in syndication library between 4.1.2 and trunk?

There weren't. I got it to build after some major mods to the CMakeLists.txt file. You can find the one that just worked for me below ( can't post attachements here )

Code: Select all

find_package(KDE4 REQUIRED)
find_package(Plasma REQUIRED)
find_package(KdepimLibs REQUIRED)
include (KDE4Defaults)
include (MacroLibrary)
include(MacroOptionalAddSubdirectory)
include(MacroOptionalDependPackage)

find_package(Boost REQUIRED)

add_definitions (${QT_DEFINITIONS} ${KDE4_DEFINITIONS} -DHAVE_CONFIG_H=1)
include_directories (${CMAKE_SOURCE_DIR} ${CMAKE_BINARY_DIR} ${KDE4_INCLUDES} ${Boost_INCLUDE_DIR})

set(rss_engine_SRCS
    rss.cpp
)

kde4_add_plugin(plasma_engine_rss ${rss_engine_SRCS})
target_link_libraries(plasma_engine_rss plasma ${KDE4_KDECORE_LIBS} ${KDE4_SYNDICATION_LIBS})

install(TARGETS plasma_engine_rss DESTINATION ${PLUGIN_INSTALL_DIR})
install(FILES plasma-dataengine-rss.desktop DESTINATION ${SERVICES_INSTALL_DIR})



Yes, now it is compiled. Nice

I have installed rss dataengine, but (after restart KDE session) I still can't see 'rss' in plasmaengineexplorer. Files are installed in correct places (like other dataengines):
/usr/lib/kde4/plasma_engine_rss.so
/usr/share/kde4/services/plasma-dataengine-rss.desktop

Of course, RSSNOW still "fetching feeds" without success... Any ideas?

I got it to appear in plasmaengineexplorer by editing the "plasma-dataengine-rss.desktop" file.

Change: ServiceTypes to X-KDE-ServiceTypes
And add: X-Plasma-EngineName=rss

I just installed RSSNOW, and it is working. You may have to run sudo make install in the rss dataengine build folder after the modification to make it update the file.

Yes, great! It works!

Let me summarize:
1. Grab sources and compile rss dataengine.
- svn co svn://anonsvn.kde.org/home/kde/trunk/KD ... ngines/rss
- create brand-new CMakeLists.txt (post #8)
- edit plasma-dataengine-rss.desktop and change: ServiceTypes to X-KDE-ServiceTypes, add line: X-Plasma-EngineName=rss
- mkdir build; cd build; cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
- make
- su; make install

2. Grab RSSNOW sources and compile it.
- svn co svn://anonsvn.kde.org/home/kde/trunk/kd ... ets/rssnow
- mkdir build; cd build; cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
- make
- su; make install

3. Logout & Login (or simply restart plasma)
4. Add RSSNOW widget, have fun

Thank you bcooksley and aseigo!

Hello!Please I have a problem building the machine, can you help me?Here's my post:

http://bbs.archlinux.org/viewtopic.php?pid=441867#p441867

Restarting plasma is not needed. Just run kbuildsycoca4

rssnow lives at:
svn co svn://anonsvn.kde.org/home/kde/trunk/KD ... ets/rssnow

Hello. I am new to this forum so i want to say hello to all.
I got rssnow with KDE 4.2 so i didn't have to do all that u wrote above. It was just ready after installation. Anyway it is not working. Neither Rssnow nor news widget. I see all the time fetching feed. After clicking on it i got konqueror opened showing my Documents.
Any idea how to fix it??
