I'm afraid I can't get plasma5-plasma-desktop to build either. It fails with exactly the same error that Stefan Rumetshofer reported. I have tried to build it several times. I am using poudriere with 12 current. I have tried to build it using MAKE_JOBS_UNSAFE as well and it still will not build. A couple of CMake warnings I see from the build log:
CMake Warning (dev) at /usr/local/lib/cmake/KF5Package/KF5PackageMacros.cmake:26 (message): Deprecated: use kpackage_install_bundled_package Call Stack (most recent call first): kcms/lookandfeel/CMakeLists.txt:59 (kpackage_install_package) This warning is for project developers. Use -Wno-dev to suppress it. CMake Warning at /usr/local/lib/cmake/KF5Package/KF5PackageMacros.cmake:73 (message): KPackage components should be specified in reverse domain notation. Appstream information won't be generated for kcm_lookandfeel. Call Stack (most recent call first): kcms/lookandfeel/CMakeLists.txt:59 (kpackage_install_package) I am scratching my head on this one. Thanks for your help in advance, Jeremy Cox
