Autogenerated code in trace.h/trace.c and friends is specific to the config-host.mak TRACE_BACKENDS setting and must be regenerated when ./configure --enable-trace-backend= changes settings.
This patch ensures that changes to TRACE_BACKENDS are detected. For example, the trace-root.h file is now updated after switching trace backends: $ ./configure && make $ cp trace-root.h /tmp/old-trace-root.h $ ./configure --enable-trace-backend=simple && make $ diff -u /tmp/old-trace-root.h trace-root.h Reported-by: Christophe Lyon <christophe.l...@st.com> Signed-off-by: Stefan Hajnoczi <stefa...@redhat.com> --- Makefile | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/Makefile b/Makefile index de898eab62..4e70cebc6a 100644 --- a/Makefile +++ b/Makefile @@ -145,7 +145,7 @@ tracetool-y += $(shell find $(SRC_PATH)/scripts/tracetool -name "*.py") %/trace.h: %/trace.h-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -%/trace.h-timestamp: $(SRC_PATH)/%/trace-events $(tracetool-y) +%/trace.h-timestamp: $(SRC_PATH)/%/trace-events $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=$(call trace-group-name,$@) \ --format=h \ @@ -154,7 +154,7 @@ tracetool-y += $(shell find $(SRC_PATH)/scripts/tracetool -name "*.py") %/trace.c: %/trace.c-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -%/trace.c-timestamp: $(SRC_PATH)/%/trace-events $(tracetool-y) +%/trace.c-timestamp: $(SRC_PATH)/%/trace-events $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=$(call trace-group-name,$@) \ --format=c \ @@ -163,7 +163,7 @@ tracetool-y += $(shell find $(SRC_PATH)/scripts/tracetool -name "*.py") %/trace-ust.h: %/trace-ust.h-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -%/trace-ust.h-timestamp: $(SRC_PATH)/%/trace-events $(tracetool-y) +%/trace-ust.h-timestamp: $(SRC_PATH)/%/trace-events $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=$(call trace-group-name,$@) \ --format=ust-events-h \ @@ -187,7 +187,7 @@ tracetool-y += $(shell find $(SRC_PATH)/scripts/tracetool -name "*.py") trace-root.h: trace-root.h-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -trace-root.h-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) +trace-root.h-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=root \ --format=h \ @@ -196,7 +196,7 @@ trace-root.h-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) trace-root.c: trace-root.c-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -trace-root.c-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) +trace-root.c-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=root \ --format=c \ @@ -205,7 +205,7 @@ trace-root.c-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) trace-ust-root.h: trace-ust-root.h-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -trace-ust-root.h-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) +trace-ust-root.h-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=root \ --format=ust-events-h \ @@ -214,7 +214,7 @@ trace-ust-root.h-timestamp: $(SRC_PATH)/trace-events $(tracetool-y) trace-ust-all.h: trace-ust-all.h-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -trace-ust-all.h-timestamp: $(trace-events-files) $(tracetool-y) +trace-ust-all.h-timestamp: $(trace-events-files) $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=all \ --format=ust-events-h \ @@ -223,7 +223,7 @@ trace-ust-all.h-timestamp: $(trace-events-files) $(tracetool-y) trace-ust-all.c: trace-ust-all.c-timestamp @cmp $< $@ >/dev/null 2>&1 || cp $< $@ -trace-ust-all.c-timestamp: $(trace-events-files) $(tracetool-y) +trace-ust-all.c-timestamp: $(trace-events-files) $(tracetool-y) $(BUILD_DIR)/config-host.mak $(call quiet-command,$(TRACETOOL) \ --group=all \ --format=ust-events-c \ -- 2.20.1
