我有以下规则
define compile_c
$(ECHO) "CC $<"
$(Q)$(CC) $(CFLAGS) -c -MD -o $@ $<
@# The following fixes the dependency file.
@# See http://make.paulandlesley.org/autodep.html for details.
@# Regex adjusted from the above to play better with Windows paths, etc.
@$(CP) $(@:.o=.d) $(@:.o=.P); \
$(SED) -e 's/#.*//' -e 's/^.*: *//' -e 's/ *\\$$//' \
-e '/^$$/ d' -e 's/$$/ :/' < $(@:.o=.d) >> $(@:.o=.P); \
$(RM) -f $(@:.o=.d)
endef
vpath %.c . $(TOP)
$(BUILD)/%.o: %.c $(BUILD)/%.pp
$(call compile_c)
vpath %.c . $(TOP)
$(BUILD)/%.pp: %.c
$(ECHO) "PreProcess $<"
$(Q)$(CC) $(CFLAGS) -E -Wp,-C,-dD,-dI -o $@ $<
当编译完成后,GNU make会打印
Removing intermediate files...
并删除所有的 .pp
文件,但我不希望这样。
为什么会这样?
该怎么停止它?
