Makefile中TARGET_ARCH变量的用途是什么 [英] What is purpose of TARGET_ARCH variable in Makefiles

问题描述

我注意到在Gnu Make的隐式规则中，变量$(TARGET_ARCH)例如:

I have noticed that in Implicit Rules in Gnu Make is variable $(TARGET_ARCH) for example :

$(LINK.o) $^ $(LOADLIBES) $(LDLIBS) -o $@
LINK.o = $(CC) $(LDFLAGS) $(TARGET_ARCH)

我认为此变量是交叉编译所必需的，但是我在Gnu Make文档中找不到有关此变量的任何信息.

I supposed that this variable is needed for cross compilation, but I haven't found any information about it in Gnu Make documentation.

推荐答案

我同意它可能用于交叉编译. 变量TARGET_ARCH没有默认值-最终用户可以在其中定义自己认为合适的变量.

I agree that it's probably meant for cross-compilation. The variable TARGET_ARCH has no default value - it's there for end-users to define as they see fit.
