Follow the steps given below to build the code. 1. Build KDE 4 from source - use kdesvn-build from http://kdesvn-build.kde.org/ - build only kdelibs and kdebase - take qt from your distro (if older than 4.4, build qt-copy as well) 2. Sync files from smc git to kde source tree - rsync -av --progress /calendar/kde/* 3. Run tests - go to /build/kdelibs - make kcalendartest - run kdecore/tests/kcalendartest - kdecore/tests/kcalendartest -functions (for listing available tests) - kdecore/tests/kcalendartest testName -v2 (for running named test with detailed output) See video of the working calendar http://blip.tv/file/1656477
