From f89fb55714b620ff1352141a9f9315611f16573e Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Mon, 2 Jan 2023 23:09:16 -0800 Subject: perf build: Don't propagate subdir to submakes for install_headers subdir is added to the OUTPUT which fails as part of building install_headers when passed from "make -C tools perf_install". Committer testing: The original reporter (see the Link: below) had trouble with this: $ make -C tools perf_install That ended up with errors like this: /var/home/acme/git/perf-urgent/tools/scripts/Makefile.include:17: *** output directory "/var/home/acme/git/perf-urgent/tools/perf/libperf/perf/" does not exist. Stop. With this patch applied we now get it installed at: INSTALL /var/home/acme/git/perf-urgent/tools/perf/libperf/include/perf/bpf_perf.h As expected: $ ls -la /var/home/acme/git/perf-urgent/tools/perf/libperf/include/perf/bpf_perf.h -rw-r--r--. 1 acme acme 1146 Jan 3 15:42 /var/home/acme/git/perf-urgent/tools/perf/libperf/include/perf/bpf_perf.h And if we clean tools with: $ make -C tools clean it gets cleaned up: $ ls -la /var/home/acme/git/perf-urgent/tools/perf/libperf/include/perf/bpf_perf.h ls: cannot access '/var/home/acme/git/perf-urgent/tools/perf/libperf/include/perf/bpf_perf.h': No such file or directory $ Fixes: 746bd29e348f99b4 ("perf build: Use tools/lib headers from install path") Reported-by: Torsten Hilbrich Signed-off-by: Ian Rogers Tested-by: Arnaldo Carvalho de Melo Cc: Alexander Shishkin Cc: Ingo Molnar Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Link: https://lore.kernel.org/r/fa4b3115-d555-3d7f-54d1-018002e99350@secunet.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/Makefile.perf | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'tools') diff --git a/tools/perf/Makefile.perf b/tools/perf/Makefile.perf index 13e7d26e77f0..1e32c93b8042 100644 --- a/tools/perf/Makefile.perf +++ b/tools/perf/Makefile.perf @@ -819,7 +819,7 @@ $(patsubst perf-%,%.o,$(PROGRAMS)): $(wildcard */*.h) $(LIBAPI): FORCE | $(LIBAPI_OUTPUT) $(Q)$(MAKE) -C $(LIBAPI_DIR) O=$(LIBAPI_OUTPUT) \ - DESTDIR=$(LIBAPI_DESTDIR) prefix= \ + DESTDIR=$(LIBAPI_DESTDIR) prefix= subdir= \ $@ install_headers $(LIBAPI)-clean: @@ -828,7 +828,7 @@ $(LIBAPI)-clean: $(LIBBPF): FORCE | $(LIBBPF_OUTPUT) $(Q)$(MAKE) -C $(LIBBPF_DIR) FEATURES_DUMP=$(FEATURE_DUMP_EXPORT) \ - O= OUTPUT=$(LIBBPF_OUTPUT)/ DESTDIR=$(LIBBPF_DESTDIR) prefix= \ + O= OUTPUT=$(LIBBPF_OUTPUT)/ DESTDIR=$(LIBBPF_DESTDIR) prefix= subdir= \ $@ install_headers $(LIBBPF)-clean: @@ -837,7 +837,7 @@ $(LIBBPF)-clean: $(LIBPERF): FORCE | $(LIBPERF_OUTPUT) $(Q)$(MAKE) -C $(LIBPERF_DIR) O=$(LIBPERF_OUTPUT) \ - DESTDIR=$(LIBPERF_DESTDIR) prefix= \ + DESTDIR=$(LIBPERF_DESTDIR) prefix= subdir= \ $@ install_headers $(LIBPERF)-clean: @@ -846,7 +846,7 @@ $(LIBPERF)-clean: $(LIBSUBCMD): FORCE | $(LIBSUBCMD_OUTPUT) $(Q)$(MAKE) -C $(LIBSUBCMD_DIR) O=$(LIBSUBCMD_OUTPUT) \ - DESTDIR=$(LIBSUBCMD_DESTDIR) prefix= \ + DESTDIR=$(LIBSUBCMD_DESTDIR) prefix= subdir= \ $@ install_headers $(LIBSUBCMD)-clean: @@ -855,7 +855,7 @@ $(LIBSUBCMD)-clean: $(LIBSYMBOL): FORCE | $(LIBSYMBOL_OUTPUT) $(Q)$(MAKE) -C $(LIBSYMBOL_DIR) O=$(LIBSYMBOL_OUTPUT) \ - DESTDIR=$(LIBSYMBOL_DESTDIR) prefix= \ + DESTDIR=$(LIBSYMBOL_DESTDIR) prefix= subdir= \ $@ install_headers $(LIBSYMBOL)-clean: -- cgit v1.2.3-58-ga151
