Makefile（不区分大小写的目标）(Makefile (non-case sensitive goals))

当使用makefile时，我希望以下是可能的：

make clean make Clean make CLean make CLEan make CLEAn make ...

并且在我的makefile中都做同样的事情。 （即我不想让目标区分大小写）

当然，我可以写这样的每一个可能性：

.PHONY clean Clean CLean CLEan CLEAn ... clean Clean CLean CLEan CLEAn ...: $(DELETE_STUFF)

但我想你可以看到为什么这是不希望的.. 我知道'make'有一个名为MAKECMDGOALS的内置宏，它将与键入make后输入的内容相等。

for example, running 'make clean all backup' $(MAKECMDGOALS) = "clean all backup"

我试图在我的makefile的顶部执行此操作：

MAKECMDGOALS:= $(shell echo $(MAKECMDGOALS) | tr "[:upper:]" "[:lower:]")

它会将变量更改为全部小写，但仍然只会针对输入的目标目标调用规则。

我甚至试图像这样覆盖它：

override MAKECMDGOALS:= $(shell echo $(MAKECMDGOALS) | tr "[:upper:]" "[:lower:]")

希望尽快完成，但没有成功。

我打算制定一个这样的目标：

$(MAKECMDGOALS): MAKECMDGOALS:= $(shell echo $(MAKECMDGOALS) | tr "[:upper:]" "[:lower:]") #BUT I CAN'T CALL OTHER TARGETS FROM THE SHELL

我知道这是一个愚蠢的细节，但肯定有一个方法是正确的？

when using a makefile, I want the following to be possible:

make clean make Clean make CLean make CLEan make CLEAn make ...

and have all to do the same thing in my makefile. (ie. I don't want make goals to be case sensitive)

Sure, I could just write every possibly like this:

.PHONY clean Clean CLean CLEan CLEAn ... clean Clean CLean CLEan CLEAn ...: $(DELETE_STUFF)

but I think you can see why this is not desired.. I know that 'make' has a built in macro called: MAKECMDGOALS which will be equal to whatever you type after typing make.

for example, running 'make clean all backup' $(MAKECMDGOALS) = "clean all backup"

I tried to do this at the top of my makefile:

MAKECMDGOALS:= $(shell echo $(MAKECMDGOALS) | tr "[:upper:]" "[:lower:]")

it does change the variable to all lowercase, but will still only call the rule for the target goal typed.

I've even tried to override it like this:

override MAKECMDGOALS:= $(shell echo $(MAKECMDGOALS) | tr "[:upper:]" "[:lower:]")

in hopes that will be done sooner, yet no success.

I was going to make a target like this:

$(MAKECMDGOALS): MAKECMDGOALS:= $(shell echo $(MAKECMDGOALS) | tr "[:upper:]" "[:lower:]") #BUT I CAN'T CALL OTHER TARGETS FROM THE SHELL

I know it's a silly detail to fuss over, but surely there has got to be a way right?

最满意答案

原油但有效：

%: $(MAKE) $(shell echo $@ | tr "[:upper:]" "[:lower:]") clean: delete_stuff

Crude but effective:

%: $(MAKE) $(shell echo $@ | tr "[:upper:]" "[:lower:]") clean: delete_stuff
