Just discussed this a bit with Stephen on IRC: We need to set the compile flags manually on each static library used in a shared library -- there's no way for CMake to figure out if a static library will be added to a shared one. So, we have to specify set_target_properties(MyStaticLib PROPERTIES POSITION_INDEPENDENT_CODE TRUE) manually for each of them Also see: http://cmake.3232098.n2.nabble.com/SHARED-library-containing-OBJECT-library-Missing-fPIC-tp7580514p7580571.html I'll file some patches Greets -- Kevin Funk _______________________________________________ Kde-frameworks-devel mailing list Kde-frameworks-devel@kde.org https://mail.kde.org/mailman/listinfo/kde-frameworks-devel
