I tried to upgrade my KDE SC installation to 4.7 RC2 and KAlgebra failed with this: (...) -- Found Phonon: /usr/include -- Performing Test _OFFT_IS_64BIT -- Performing Test _OFFT_IS_64BIT - Failed -- Performing Test HAVE_FPIE_SUPPORT -- Performing Test HAVE_FPIE_SUPPORT - Success -- Performing Test __KDE_HAVE_W_OVERLOADED_VIRTUAL -- Performing Test __KDE_HAVE_W_OVERLOADED_VIRTUAL - Success -- Performing Test __KDE_HAVE_GCC_VISIBILITY -- Performing Test __KDE_HAVE_GCC_VISIBILITY - Success -- Found KDE 4.7 include dir: /usr/include -- Found KDE 4.7 library dir: /usr/lib -- Found the KDE4 kconfig_compiler preprocessor: /usr/bin/kconfig_compiler -- Found automoc4: /usr/bin/automoc4 CMake Error at CMakeLists.txt:7 (find_package): Could not find module FindLibKdeEdu.cmake or a configuration file for package LibKdeEdu. Adjust CMAKE_MODULE_PATH to find FindLibKdeEdu.cmake or set LibKdeEdu_DIR to the directory containing a CMake configuration file for LibKdeEdu. The file will have one of the following names: LibKdeEduConfig.cmake libkdeedu-config.cmake (...) After emerging kde-base/libkdeedu by hand it worked good. I didn't test other kdeedu apps.
confirming for in-tree kalgebra-4.7.0
Changing summary as the bug went into the main tree.
Fixed, thanks.
