With CMAKE_MAKEFILE_GENERATOR=ninja. >>> Working in BUILD_DIR: "/x/portage/kde-plasma/kinfocenter-5.13.4/work/kinfocenter-5.13.4_build" ninja -v -j6 -l0 ninja: error: build.ninja:2386: multiple rules generate /x/portage/kde-plasma/kinfocenter-5.13.4/work/kinfocenter-5.13.4/Modules/base/config-infocenter.h.cmake [-w dupbuild=err]
For me 5.13.4 worked fine, but the issue popped up with 5.13.5. The failure was caused by ninja-2.8.1-r1, which is the Kitware-fork [1]. Upstream 1.8.2 works fine. No idea how to deal with the Ninja-Tracker-block in this case. [1] https://github.com/gentoo/gentoo/pull/9183
CCing ninja maintainers then.
(In reply to Andreas Sturmlechner from comment #2) > CCing ninja maintainers then. I am the ninja maintainer ;-). I will try to reproduce without the kitware patches; if vanilla ninja works, 1.8.2-r1 is getting masked.
The Kitware fork is based on a post-1.8.2 version of upstream Ninja from their 'master' branch. It includes this upstream change: * make `-w dupbuild` default to `err` https://github.com/ninja-build/ninja/pull/1406 That will be released in upstream Ninja 1.9. A "multiple rules generate" diagnostic from Ninja means that the build.ninja file needs to be fixed. A packager can pass `-w dupbuild=warn` to ninja to convert the error back to a warning, but the underlying problem needs to be fixed in the build.ninja file eventually.
(In reply to Brad King from comment #4) Thank you for the information.

Not reproducible anymore for me with: dev-util/ninja-1.8.2-r2 dev-util/cmake-3.13.4
This is passing successfully for me on both stable and testing.
