例5-2的func函数返回值依旧是一个makefile规则的表达式,这时候如果需要执行这个规则,那就要使用makefile的规则对其进行再一次地解析,就需要用到eval()函数,eval()函数通常与call()一起使用。 例5-2第三行中出现的"$$",在makefile的语法中,$是一个特殊字符,通常与其他符号结合表示特定的含义,如果我们单纯的就...
$(flavor variable) var2 = flavor function var3 := flavor funciton all: @echo $(flavor var1) # undefined 未定义 @echo $(flavor var2) # recursive 递归展开赋值 @echo $(flavor var3) # simple 简单赋值 eval 可以将一段文本生成Makefile的内容 $(eval text) define eval_target =...

递归赋值(recursive assignment) 递归赋值的符号为=,在递归赋值时,每次调用变量时,变量的值都会被动态计算(区别于简单赋值)。如CC = ${GCC} ${FLAGS},如果一开始变量GCC被设为gcc,FLAGS被设为-w,那么CC就为gcc -w。如果之后将GCC改为了GCC = g++,那么在此之后遇到CC,其值会被更新,变为g++ -w。

we inline foo into func twice, generate (because they're address is taken) temporary storage for 1,2,3 & 4,5,6, but then we don't realize that, because they're scope-local address taken variables (so any global function that may be using these addresses after the end...
