Hi all, After merging the tip tree, today's linux-next build (perf) failed like this: make[3]: *** No rule to make target 'tools/lib/api/fs/debugfs.h', needed by 'tools/perf/arch/common.o'. Stop. tools/build/Makefile.build:109: recipe for target 'arch' failed make[4]: *** No rule to make target 'fs/debugfs.h', needed by 'tools/perf/fs/fs.o'. Stop. tools/build/Makefile.build:109: recipe for target 'fs' failed make[3]: *** No rule to make target 'tools/lib/api/fs/debugfs.h', needed by 'tools/perf/util/abspath.o'. Stop. tools/build/Makefile.build:109: recipe for target 'util' failed Makefile:32: recipe for target 'tools/perf/libapi-in.o' failed Makefile.perf:417: recipe for target 'tools/perf/libapi.a' failed Makefile.perf:393: recipe for target 'tools/perf/libperf-in.o' failed Makefile:68: recipe for target 'all' failed Maybe caused by commit 60a1133a5b39 ("tools lib api fs: Remove debugfs, tracefs and findfs objects") This is an incremental build i.e. I do not do a "make clean" after doing the build for each tree merge (in case that matters). I have used the tip tree from next-20150915 for today. Also, building perf seems to ignore O=<dir> on the make invocation. Is that expected? -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
