I noticed some commits in the tip tree today that seemed as though they
were addressing this problem. However, I still get a build failure if
I don't clean out the object directory before building tools/perf:
BUILD: Doing 'make -j48' parallel build
GEN /home/sfr/next/perf/common-cmds.h
CC /home/sfr/next/perf/fixdep.o
LD /home/sfr/next/perf/fixdep-in.o
LINK /home/sfr/next/perf/fixdep
CC /home/sfr/next/perf/perf-read-vdso32
CC /home/sfr/next/perf/perf-read-vdsox32
make[3]: *** No rule to make target '/home/sfr/next/next/tools/lib/api/fs/debugfs.h', needed by '/home/sfr/next/perf/ui/gtk/browser.o'. Stop.
/home/sfr/next/next/tools/build/Makefile.build:116: recipe for target 'ui/gtk' failed
make[2]: *** [ui/gtk] Error 2
Makefile.perf:310: recipe for target '/home/sfr/next/perf/gtk-in.o' failed
(/home/sfr/next/perf/ is the object directory)

it won't fix the build if you still have old .cmd file in you tree (I presume that's the case),
once those are regenerated you shouldn't meet the issue again

Its fine, I have automated the clean up of the perf build object directory after merging the tip tree. However, this will also happen to anyone who has built perf then updates their tree and then tries to rebuild perf. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
