Variable Assignment ------------------- Variable definitions are parsed as follows: IMMEDIATE = DEFERRED IMMEDIATE ?= DEFERRED IMMEDIATE := IMMEDIATE IMMEDIATE += DEFERRED or IMMEDIATE define IMMEDIATE DEFERRED endef define IMMEDIATE = DEFERRED endef define IMMEDIATE ?= DEFERRED endef define IMMEDIATE := IMMEDIATE endef define IMMEDIATE += DEFERRED or IMMEDIATE endef For the append operator, `+=', the right-hand side is considered immediate if the variable was previously set as a simple variable (`:='), and deferred otherwise.

變量定義被如下解析：

IMMEDIATE = DEFERRED
IMMEDIATE ?= DEFERRED
IMMEDIATE := IMMEDIATE
IMMEDIATE += DEFERRED or IMMEDIATE

define IMMEDIATE
DEFERRED
endef

define IMMEDIATE =
DEFERRED
endef

define IMMEDIATE ?=
DEFERRED
endef

define IMMEDIATE :=
IMMEDIATE
endef

define IMMEDIATE +=
DEFERRED or IMMEDIATE
endef

?

For the append operator, `+=', the right-hand side is considered
immediate if the variable was previously set as a simple variable
(`:='), and deferred otherwise.

對(duì)于連接符號(hào) +=， 如果變量已經(jīng)被定義為一個(gè)簡單變量(:=)，那么右手邊就被認(rèn)為是立即性的，

否則就是推遲性的。
