在上一篇文章中我们进行了~/Share/SDK/et_app/makefile文件的分析:https://bbs.elecfans.com/forum.ph ... 1&extra=#pid5319708 我们知道~/Share/SDK/et_app/makefile只是定义了一些变量,主要的就是连接变量,然后make语句会包含~/Share/SDK/makefile也就是主目录的makefile,也就是说程序就执行到了主目录,现在让我们看看makefile的内容: # copyright (c) 2010 Espressif System # ifndef PDIR endif ifeq ($(COMPILE), xcc) AR = xt-ar CC = xt-xcc NM = xt-nm CPP = xt-xt++ OBJCOPY = xt-objcopy OBJDUMP = xt-objdump else AR = xtensa-lx106-elf-ar CC = xtensa-lx106-elf-gcc NM = xtensa-lx106-elf-nm CPP = xtensa-lx106-elf-g++ OBJCOPY = xtensa-lx106-elf-objcopy OBJDUMP = xtensa-lx106-elf-objdump endif BOOT?=none APP?=0 SPI_SPEED?=40 SPI_MODE?=QIO SPI_SIZE_MAP?=0 ifeq ($(BOOT), new) boot = new else ifeq ($(BOOT), old) boot = old else boot = none endif endif ifeq ($(APP), 1) app = 1 else ifeq ($(APP), 2) app = 2 else app = 0 endif endif ifeq ($(SPI_SPEED), 26.7) freqdiv = 1 else ifeq ($(SPI_SPEED), 20) freqdiv = 2 else ifeq ($(SPI_SPEED), 80) freqdiv = 15 else freqdiv = 0 endif endif endif ifeq ($(SPI_MODE), QOUT) mode = 1 else ifeq ($(SPI_MODE), DIO) mode = 2 else ifeq ($(SPI_MODE), DOUT) mode = 3 else mode = 0 endif endif endif addr = 0x01000 ifeq ($(SPI_SIZE_MAP), 1) size_map = 1 flash = 256 else ifeq ($(SPI_SIZE_MAP), 2) size_map = 2 flash = 1024 ifeq ($(app), 2) addr = 0x81000 endif else ifeq ($(SPI_SIZE_MAP), 3) size_map = 3 flash = 2048 ifeq ($(app), 2) addr = 0x81000 endif else ifeq ($(SPI_SIZE_MAP), 4) size_map = 4 flash = 4096 ifeq ($(app), 2) addr = 0x81000 endif else ifeq ($(SPI_SIZE_MAP), 5) size_map = 5 flash = 2048 ifeq ($(app), 2) addr = 0x101000 endif else ifeq ($(SPI_SIZE_MAP), 6) size_map = 6 flash = 4096 ifeq ($(app), 2) addr = 0x101000 endif else size_map = 0 flash = 512 ifeq ($(app), 2) addr = 0x41000 endif endif endif endif endif endif endif LD_FILE = $(LDDIR)/eagle.app.v6.ld ifneq ($(boot), none) ifneq ($(app),0) ifeq ($(size_map), 6) LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).2048.ld else ifeq ($(size_map), 5) LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).2048.ld else ifeq ($(size_map), 4) LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).1024.app$(app).ld else ifeq ($(size_map), 3) LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).1024.app$(app).ld else ifeq ($(size_map), 2) LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).1024.app$(app).ld else ifeq ($(size_map), 0) LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).512.app$(app).ld endif endif endif endif endif endif BIN_NAME = user$(app).$(flash).$(boot).$(size_map) endif else app = 0 endif CSRCS ?= $(wildcard *.c) CPPSRCS ?= $(wildcard *.cpp) ASRCs ?= $(wildcard *.s) ASRCS ?= $(wildcard *.S) SUBDIRS ?= $(patsubst %/,%,$(dir $(wildcard */Makefile))) ODIR := .output OBJODIR := $(ODIR)/$(TARGET)/$(FLAVOR)/obj OBJS := $(CSRCS:%.c=$(OBJODIR)/%.o) $(CPPSRCS:%.cpp=$(OBJODIR)/%.o) $(ASRCs:%.s=$(OBJODIR)/%.o) $(ASRCS:%.S=$(OBJODIR)/%.o) DEPS := $(CSRCS:%.c=$(OBJODIR)/%.d) $(CPPSRCS:%.cpp=$(OBJODIR)/%.d) $(ASRCs:%.s=$(OBJODIR)/%.d) $(ASRCS:%.S=$(OBJODIR)/%.d) LIBODIR := $(ODIR)/$(TARGET)/$(FLAVOR)/lib OLIBS := $(GEN_LIBS:%=$(LIBODIR)/%) IMAGEODIR := $(ODIR)/$(TARGET)/$(FLAVOR)/image OIMAGES := $(GEN_IMAGES:%=$(IMAGEODIR)/%) BINODIR := $(ODIR)/$(TARGET)/$(FLAVOR)/bin OBINS := $(GEN_BINS:%=$(BINODIR)/%) CCFLAGS += -g -Wpointer-arith -Wundef -Werror -Wl,-EL -fno-inline-functions -nostdlib -mlongcalls -mtext-section-literals -ffunction-sections -fdata-sections # -Wall CFLAGS = $(CCFLAGS) $(DEFINES) $(EXTRA_CCFLAGS) $(INCLUDES) DFLAGS = $(CCFLAGS) $(DDEFINES) $(EXTRA_CCFLAGS) $(INCLUDES) ############################################################# # Functions # define ShortcutRule $(1): .subdirs $(2)/$(1) endef define MakeLibrary DEP_LIBS_$(1) = $$(foreach lib,$$(filter %.a,$$(COMPONENTS_$(1))),$$(dir $$(lib))$$(LIBODIR)/$$(notdir $$(lib))) DEP_OBJS_$(1) = $$(foreach obj,$$(filter %.o,$$(COMPONENTS_$(1))),$$(dir $$(obj))$$(OBJODIR)/$$(notdir $$(obj))) $$(LIBODIR)/$(1).a: $$(OBJS) $$(DEP_OBJS_$(1)) $$(DEP_LIBS_$(1)) $$(DEPENDS_$(1)) @MKDIR -p $$(LIBODIR) $$(if $$(filter %.a,$$?),mkdir -p $$(EXTRACT_DIR)_$(1)) $$(if $$(filter %.a,$$?),cd $$(EXTRACT_DIR)_$(1);
