停止执行makefile [英] Stop executing makefile

问题描述

我实现了一个配方，以便将所有剩余的字符串传递给命令，例如此脚本中的示例:

I implement a recipe in order to pass all the remaining string to the command, as example in this script:

Makefile

run:
#   ./bin/run.sh $(filter-out $@,$(MAKECMDGOALS)) 
    @echo $(filter-out $@,$(MAKECMDGOALS))

但是当我作为示例运行时:

But when I run as example:

>make run my custom input params
my custom input params
make: *** No rule to make target `my'.  Stop.

makefile尝试也执行剩余的字符串，因此出现错误:

makefile try to execute also the remaining string so the error:

make: *** No rule to make target `my'.  Stop.

如何防止这种情况?

注意:作为解决方法，我定义了一个虚拟配方:

NB: As workaround I define a dummy recipe:

%:
    @echo

因此，这将打印一个空字符串而不是错误.

So this will print an empty string instead of the error.

我想避免做类似的事情:

I want to avoid to do something like:

make run-example param="my custom param"

推荐答案

我认为您不应该使用Makefile.您想对选项进行自己的解析，而在make中做起来比较麻烦.

I don't think you should use a Makefile. You want to do your own parsing of the options, and that's more trouble to do in make.

如果您对它不满意，可以执行以下操作:

If you're dead set on it, you could do this:

%:
    @true

...这将避免打印空行.

...which will avoid printing an empty line.

不过，最好在Bash中执行此操作.这是您可以做到的一种方法:

It would be better to do this in Bash, though. Here's one way you could do it:

#!/usr/bin/env bash

if [ $# -lt 1 ]; then
    echo Not enough args
    exit 1
fi

case "$1" in
    "run")
        shift
        ./bin/run.sh $@
        ;;
    *)
        echo "Command $1 not recognized"
        exit 1
        ;;
esac

这似乎更容易且可扩展.

This seems easier and more extensible.
