makefile 系统脚本分析
1，系统编译配置文件脚本目录~/8368U.TD/build/Kconfig
一）比喻配置屏幕分表率，比喻配置GLB_GMNCFG_ENABLE_800_480_UI
~/8368U.TD/build/Kconfig
menu "Gemini UI Setting" choice prompt "UI Framework Selection" default GLB_GMNCFG_ENABLE_QT_FRAMEWORK config GLB_GMNCFG_ENABLE_QT_FRAMEWORK bool "Qt Framework" config GLB_GMNCFG_ENABLE_TD_FRAMEWORK bool "TD Framework" endchoice choice prompt "UI Resolution" default GLB_GMNCFG_ENABLE_1024_600_UI config GLB_GMNCFG_ENABLE_800_480_UI bool "800*480 UI" config GLB_GMNCFG_ENABLE_1024_600_UI bool "1024*600_UI" config GLB_GMNCFG_ENABLE_1280_720_UI depends on GLB_GMNCFG_ENABLE_TD_FRAMEWORK bool "1280*720 UI (Not support on Qt)"

2，在工程更目录下执行make命令,都会执行build/Makefile
~/8368U.TD/Makefile
include build/Makefile
3,build/Makefile分析
make help 会打印下面说明
一）make uboot 会执行“build uboot source”
make all 会执行“build uboot/ecos/kernel/sdk/app/rom source”即 分别会执行“build uboot source“、"build ecos source"..“build rom source”
make clean 会执行“clean uboot/ecos/kernel/sdk/app” 会分别执行“clean uboot”、"clean ecos" ...”clean app“
make disclean 会执行“clean uboot/ecos/kernel/sdk/app and platform config”
二）make app 流程 (分析结果：相当于执行./application下的Makefile)
I) @if [ -f $(GEMINI_APP_WRAPPER_FILE) ]; then
相当于“./application/gemini.mk”
II) $(MAKE) $(MAKE_JOBS) -f $(GEMINI_APP_WRAPPER_FILE) build
相当于"make -j CPU_NUM -f ./application/gemini.mk build"
相当于
~/8368U.TD/application/gemini.mk
build: @$(PRJ_SHOWBUILDMESG) @$(RM) -rf $(PRJ_OUTPUT_FILE) @$(MAKE) ${MAKE_JOBS} $(PRJ_EXT_PARA) -C $(APP_ROOT); \ $(PRJ_CHKBUILDRESULT);
相当于：
build:
rm -rf ./application/out/app.sqfs
make ./application
gemini.mk:11:PRJ_OUTPUT_FILE = $(APP_OUT_ROOT)$(APP_BIN_NAME)
core/setupenv.mak:112:APP_OUT_ROOT = $(APP_ROOT)out/
setupenv.mak:110:APP_ROOT = $(GEMINI_ROOT)application/
setupenv.mak:27:GEMINI_ROOT = $(TOPDIR)
core/setupenv.mak:115:APP_BIN_NAME = app.sqfs
~/8368U.TD/build/core/config_gemini.mak
126 PRJ_SHOWBUILDMESG = $(call sys_showmesg, GREEN, [BUILD] $(PRJ_NAME));\ 127 $(call sys_showmesg, LIBLUE, [TARGET] $(PRJ_OUTPUT_FILE)); \ 128 $(call sys_showmesg, BLUE, [GEMINI TARGET] $(TARGET_OUTPUT_FILE));

~/8368U.TD/build/core/config_gemini.make
101 ifeq ($(NO_PARALLEL_BUILD), 1) 102 MAKE_JOBS = 103 else 104 CPU_NUM = $(shell grep -c processor /proc/cpuinfo) 105 JOB_LIMIT = $(shell echo "${CPU_NUM} * 5 / 4" | bc) 106 LOAD_LIMIT = $(CPU_NUM) 107 MAKE_JOBS = -j $(JOB_LIMIT) -l $(LOAD_LIMIT) 108 endif
三）make clean 流程 (分析结果：相当于执行 找到application下的所有Makefile文件，执行里面的clean操作）
I）分析clean app 流程
build/core/config.mak:134:COMMAND = @set fnord $$MAKEFLAGS; amf=$$2; \
~/8368U.TD/application/build/core/config.mak 134 COMMAND = @set fnord $$MAKEFLAGS; amf=$$2; \ 135 target=`echo $@ | sed s/-recursive//`; \ 136 list='$(SUBDIRS)'; for subdir in $$list; do \ 137 if test -f $$subdir/Makefile; \ 138 then \ 139 echo "Making $$target in $$subdir"; \ 140 (cd $$subdir && $(MAKE) $(AM_MAKEFLAGS) $$target) \ 141 || case "$$amf" in *=*) exit 1;; *k*) fail=yes;; *) exit 1;; esac; \ 142 fi; \ 143 done; 144
~/8368U.TD/build/Makefile
clean: outclean @if [ -f $(GEMINI_XBOOT_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_XBOOT_WRAPPER_FILE) $@; \ fi @if [ -f $(GEMINI_UBOOT_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_UBOOT_WRAPPER_FILE) $@; \ fi @if [ -f $(GEMINI_ECOS_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_ECOS_WRAPPER_FILE) $@; \ fi @if [ -f $(GEMINI_ROOTFS_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_ROOTFS_WRAPPER_FILE) $@; \ fi @if [ -f $(GEMINI_KERNEL_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_KERNEL_WRAPPER_FILE) $@; \ fi @if [ -f $(GEMINI_SDK_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_SDK_WRAPPER_FILE) $@; \ fi @if [ -f $(GEMINI_APP_WRAPPER_FILE) ]; then \ $(MAKE) -f $(GEMINI_APP_WRAPPER_FILE) $@; \ fi @$(CLEAR) @$(call sys_showmesg, GREEN, GEMINI CLEAN DONE ! ); \
下面变量在/8368U.TD/build/core/setupenv.mak中
GEMINI_APP_WRAPPER_FILE = $(APP_ROOT)$(MAKE_WRAPPER_FILE)
APP_ROOT = $(GEMINI_ROOT)application/
GEMINI_ROOT = $(TOPDIR)
TOPDIR = ./ (~/8368U.TD/build/Makefile 中)
MAKE_WRAPPER_FILE = gemini.mk
