Description Mike Gilbert gentoo-dev 2018-08-11 20:07:38 UTC

>>> Working in BUILD_DIR: "/x/portage/kde-plasma/kinfocenter-5.13.4/work/kinfocenter-5.13.4_build"
ninja -v -j6 -l0
ninja: error: 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]
Comment 1 Franz Trischberger 2018-09-06 12:27:25 UTC
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.

Comment 2 Andreas Sturmlechner gentoo-dev 2018-09-06 18:18:50 UTC
CCing ninja maintainers then.

> 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.
Comment 4 Brad King 2018-09-14 19:00:13 UTC
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`

That will be released in upstream Ninja 1.9.

A "multiple rules generate" diagnostic from Ninja means that the 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 file eventually.

Not reproducible anymore for me with:

Comment 8 Michael Palimaka (kensington) gentoo-dev 2019-04-13 04:14:21 UTC
This is passing successfully for me on both stable and testing.

Just for the sake of clarity, I did force and verify ninja was used.
