From: Chenggang Qin <chenggang....@taobao.com> If we execute "make clean" in perf's directory, many object files cannot be cleaned in the current version. For example: While we run "make clean" in perf's directory, and run the command: "fine ./ -name "*.o"" we will get: ------------------------------------ ./arch/x86/util/unwind.o ./arch/x86/util/header.o ./arch/x86/util/dwarf-regs.o ./util/scripting-engines/trace-event-python.o ./util/scripting-engines/trace-event-perl.o ./util/probe-finder.o ./util/dwarf-aux.o ./util/unwind.o ... ... ------------------------------------ These ".o" files are not cleaned.
The reason is: These object files are added into "BUILTIN_OBJS" while "make" process check the environment. If the make command is "clean", the environment check process is not executed. So, these object files will not be added into "BUILTIN_OBJS" while we execute "make clean". This patch fixed this problem. We only add a command: "find . -name "*.o" -exec rm -f {} \;" Cc: David Ahern <dsah...@gmail.com> Cc: Peter Zijlstra <a.p.zijls...@chello.nl> Cc: Paul Mackerras <pau...@samba.org> Cc: Ingo Molnar <mi...@redhat.com> Cc: Arnaldo Carvalho de Melo <a...@ghostprotocols.net> Cc: Arjan van de Ven <ar...@linux.intel.com> Cc: Namhyung Kim <namhy...@gmail.com> Cc: Yanmin Zhang <yanmin.zh...@intel.com> Cc: Wu Fengguang <fengguang...@intel.com> Cc: Mike Galbraith <efa...@gmx.de> Cc: Andrew Morton <a...@linux-foundation.org> Signed-off-by: Chenggang Qin <chenggang....@taobao.com> --- tools/perf/Makefile | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/tools/perf/Makefile b/tools/perf/Makefile index a2108ca..dec08ba 100644 --- a/tools/perf/Makefile +++ b/tools/perf/Makefile @@ -1174,6 +1174,7 @@ clean: $(LIBTRACEEVENT)-clean $(RM) $(OUTPUT)util/*-bison* $(RM) $(OUTPUT)util/*-flex* $(python-clean) + find . -name "*.o" -exec rm -f {} \; .PHONY: all install clean strip $(LIBTRACEEVENT) .PHONY: shell_compatibility_test please_set_SHELL_PATH_to_a_more_modern_shell -- 1.7.8.rc2.5.g815b -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
