It tries to build the totem-rotation-plugin which requires the src/Totem-1.0.gir file. However src/Totem-1.0.gir has not been generated yet. The offending rule in the generated build.ninja file is this build src/plugins/sample-vala/sample-vala@sha/totem-sample-vala-plugin.c src/plugins/sample-vala/sample-vala.h src/plugins/sample-vala/sample-vala.vapi: vala_COMPILER ../totem-3.26.0/src/plugins/sample-vala/totem-sample-vala-plugin.vala which should instead read build src/plugins/sample-vala/sample-vala@sha/totem-sample-vala-plugin.c src/plugins/sample-vala/sample-vala.h src/plugins/sample-vala/sample-vala.vapi: vala_COMPILER ../totem-3.26.0/src/plugins/sample-vala/totem-sample-vala-plugin.vala || src/Totem-1.0.gir Unforunately I don't know enough about meson and ninja to figure out how to fix this. It also builds successfully if you force ninja to only use one thread. This should probably be reported upstream. Other distros may not notice this if valac picks up the system Totem-1.0.gir if Totem is already installed. -Adam
