Invoking Makefile.perf with prefix= breaks the build since Makefile.perf hands that variable down to Makefile.build where it overrides prefix := $(subst ./,,$(OUTPUT)$(dir)/) leading to errors like this: No rule to make target '/usrabspath.o', needed by '/usrlibperf-in.o' Signed-off-by: Lukas Wunner Acked-by: Jiri Olsa Cc: David Ahern Fixes: c819e2cf2eb6f65d3208d195d7a0edef6108d5 Link: http://lkml.kernel.org/r/5582c48a.84a22b0a.a918.5285SMTPIN_ADDED_MISSING@mx.google.com Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Greg Kroah-Hartman --- tools/build/Makefile.build | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) --- a/tools/build/Makefile.build +++ b/tools/build/Makefile.build @@ -94,12 +94,12 @@ obj-y := $(patsubst %/, %/$(obj)- subdir-obj-y := $(filter %/$(obj)-in.o, $(obj-y)) # '$(OUTPUT)/dir' prefix to all objects -prefix := $(subst ./,,$(OUTPUT)$(dir)/) -obj-y := $(addprefix $(prefix),$(obj-y)) -subdir-obj-y := $(addprefix $(prefix),$(subdir-obj-y)) +objprefix := $(subst ./,,$(OUTPUT)$(dir)/) +obj-y := $(addprefix $(objprefix),$(obj-y)) +subdir-obj-y := $(addprefix $(objprefix),$(subdir-obj-y)) # Final '$(obj)-in.o' object -in-target := $(prefix)$(obj)-in.o +in-target := $(objprefix)$(obj)-in.o PHONY += $(subdir-y) Patches currently in stable-queue which might be from lukas@wunner.de are queue-4.1/perf-tools-fix-build-breakage-if-prefix-is-specified.patch
