# 八、shell函数
# shell函数也不像其它的函数。顾名思义,它的参数应该就是操作系统Shell的命令。它和反引号“`”是相同的功能。这就是说,shell函数把执行操作系统命令后的输# 出作为函数返回。于是,我们可以用操作系统命令以及字符串处理命令awk,sed等等命令来生成一个变量,如:
# contents := $(shell cat foo)
# files := $(shell echo *.c)
# 注意,这个函数会新生成一个Shell程序来执行命令,所以你要注意其运行性能,如果你的Makefile中有一些比较复杂的规则,并大量使用了这个函数,那么对于你的系# 统性能是有害的。特别是Makefile的隐晦的规则可能会让你的shell函数执行的次数比你想像的多得多。

# U-boot build supports producing a object files to the separate external
# directory. Two use cases are supported:
#
# 1) Add O= to the make command line
# 'make O=/tmp/build all'
#
# 2) Set environement variable BUILD_DIR to point to the desired location
# 'export BUILD_DIR=/tmp/build'
# 'make'
#
# The second approach can also be used with a MAKEALL script
# 'export BUILD_DIR=/tmp/build'
# './MAKEALL'
#
# Command line 'O=' setting overrides BUILD_DIR environent variable.
#
# When none of the above methods is used the local build is performed and
# the object files are placed in the source directory.
#
#######################################################################################
# 七、origin函数
# origin函数不像其它的函数,他并不操作变量的值,他只是告诉你你的这个变量是哪里来的?其语法是:
# $(origin
;)
# 注意,;是变量的名字,不应该是引用。所以你最好不要在;中使用“$”字符。Origin函数会以其返回值来告诉你这个变量的“出生情况”,下# 面,是origin函数的返回值:
# “undefined”
# 如果;从来没有定义过,origin函数返回这个值“undefined”。
# “default”
# 如果;是一个默认的定义,比如“CC”这个变量,这种变量我们将在后面讲述。
# “environment”
# 如果;是一个环境变量,并且当Makefile被执行时,“-e”参数没有被打开。
# “file”
# 如果;这个变量被定义在Makefile中。
# “command line”
# 如果;这个变量是被命令行定义的。
# “override”
# 如果;是被override指示符重新定义的。
# “automatic”
# 如果;是一个命令运行中的自动化变量。关于自动化变量将在后面讲述。
# 这些信息对于我们编写Makefile是非常有用的,例如,假设我们有一个Makefile其包了一个定义文件Make.def,在 Make.def中定义了一个变量“bletch”,而我# 们的环境中也有一个环境变量“bletch”,此时,我们想判断一下,如果变量来源于环境,那么我们就把之重定义了,如果来源于Make.def或是命令行等非环境的,那# 么我们就不重新定义它。于是,在我们的Makefile中,我们可以这样写:
# ifdef bletch
# ifeq "$(origin bletch)" "environment"
# bletch = barf, gag, etc.
# endif
# endif
# 当然,你也许会说,使用override关键字不就可以重新定义环境中的变量了吗?为什么需要使用这样的步骤?是的,我们用override是可以达到这样的效果,可是 # override过于粗暴,它同时会把从命令行定义的变量也覆盖了,而我们只想重新定义环境传来的,而不想重新定义命令行传来的。

# ifdef用法
# ifdef ;
# 如果变量;的值非空,那到表达式为真。否则,表达式为假。当然,;同样可以是一个函数的返回值。注意,ifdef只是测试一# 个变量是否有值,其并不会把变量扩展到当前位置。还是来看两个例子:
# 示例一:
# bar =
# foo = $(bar)
# ifdef foo
# frobozz = yes
# else
# frobozz = no
# endif
#
# 示例二:
# foo =
# ifdef foo
# frobozz = yes
# else
# frobozz = no
# endif
# 第一个例子中,“$(frobozz)”值是“yes”,第二个则是“no”。

# ifeq (;, ;)

# ifneq (;, ;)
# ifneq ';' ';'
# ifneq ";" ";"
# ifneq ";" ';'
# ifneq ';' ";"
#
# 其比较参数“arg1”和“arg2”的值是否相同,如果不同,则为真
###############################################################################################################
ifneq ($(BUILD_DIR),)
saved-output := $(BUILD_DIR)
# Attempt to create a output directory.
# 若不存在目录的话就建立该目录包括它的你目录
$(shell [ -d ${BUILD_DIR} ] || mkdir -p ${BUILD_DIR})
################################################################################################################
# 五、if 函数
# if函数很像GNU的make所支持的条件语句——ifeq(参见前面所述的章节),if函数的语法是:
# $(if ;,;)
# 或是
# $(if ;,;,;)
# 可见,if函数可以包含“else”部分,或是不含。即if函数的参数可以是两个,也可以是三个。参数是 if的表达式,如果其返回的为非空字符串,那么 # 这个表达式就相当于返回真,于是,会被计算,否则;会被计算。
# 而if函数的返回值是,如果为真(非空字符串),那个;会是整个函数的返回值,如果;为假(空字符串),那么
# ;会是整个函数的返回值,此时如果< else-part>;没有被定义,那么,整个函数返回空字串。
# 所以,;和;只会有一个被计算。
###################################################################################################################

BUILD_DIR := $(shell cd $(BUILD_DIR) && /bin/pwd)
######################################################################################################################
#
# $(error ;)
# 产生一个致命的错误,;是错误信息。注意,error函数不会在一被使用就会产生错误信息,所以如果你把其定义在某个变量中,并在后续的脚本中使用这# 个变量,那么也是可以的。例如:
# 示例一:
#
# ifdef ERROR_001
# $(error error is $(ERROR_001))
# endif
# 示例二:
#
# ERR = $(error found an error!)
# .PHONY: err
# err: ; $(ERR)
#
# 示例一会在变量ERROR_001定义了后执行时产生error调用,而示例二则在目录err被执行时才发生error调用。

# ifndef用法
# ifndef ;
# 这个我就不多说了,和“ifdef”是相反的意思。
# 在;这一行上,多余的空格是被允许的,但是不能以[Tab]键做为开始(不然就被认为是命令)。而注释符“#”同样也是安全# # 的。“else”和“endif”也一样,只要不是以[Tab]键开始就行了。
# 特别注意的是,make是在读取Makefile时就计算条件表达式的值,并根据条件表达式的值来选择语句,所以,你最好不要把自动化变量(如“$@”等)放入条件表达式# 中,因为自动化变量是在运行时才有的。
# 而且,为了避免混乱,make不允许把整个条件语句分成两部分放在不同的文件中。

# 一、显示命令
#
# 通常,make会把其要执行的命令行在命令执行前输出到屏幕上。当我们用“@”字符在命令行前,那么,这个命令将不被make显示出来,最具代表性的例子是,我们用这个# 功能来像屏幕显示一些信息。如:
#
# @echo 正在编译XXX模块......
#
# 当make执行时,会输出“正在编译XXX模块......”字串,但不会输出命令,如果没有“@”,那么,make将输出:
#
# echo 正在编译XXX模块......
# 正在编译XXX模块......
#
# 如果make执行时,带入make参数“-n”或“--just-print”,那么其只是显示命令,但不会执行命令,这个功能很有利于我们调试我们的Makefile,看看我们书写的# 命令是执行起来是什么样子的或是什么顺序的。
