--- Comment #2 from uwesto...@web.de --- rebuilding karchive doesn't help It does not only complain with karchive but with all other KF5 packages used by labplot: KF5Archive, KF5Completion, KF5Config ... I thought it might be a problem with Qt and therefore tried to use the prebuilt librarion directly from the Qt installer. In my craftsettings.ini and have now this: [QtSDK] ## For advanced users only ## Whether to use prebuild Qt binaries. Enabled = True ## The path to the Qt sdk. Path = C:\Qt\Qt5.9.2\5.9.2\msvc2015_64\bin ## The version of Qt. Version = 5.9.2 ## The compiler version, if you are not sure what to use, have a look into the derectory set in QtSDK/Path. ## The compiler must be of the same type as General/KDECOMPILER. ## If you are using mingw please make sure you have installed the mingw using the Qt installer. Compiler = msvc2015_64 But then I get this error when recompiling karchive: Could not find a package configuration file provided by "Qt5" (requested version 5.7.0) with any of the following names: Qt5Config.cmake qt5-config.cmake Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR" to a directory containing one of the above files. If "Qt5" provides a separate development package or SDK, be sure it has been installed. But in the path I specified: C:\Qt\Qt5.9.2\5.9.2\msvc2015_64\bin there is the Qt5Config.cmake I don't know how to proceed. -- You are receiving this mail because: You are watching all bug changes.
