Makefile中规则的参数 [英] Parameter for rule in Makefile

问题描述

我需要制作一个Makefile，它应该具有run规则.但是，运行需要一些参数.

I need to make a Makefile, and it should have a run rule. However, the run requires some parameters.

有人知道在Makefile中运行规则时如何传递参数吗?我希望能够通过键入make run foo bar来运行带有参数的run规则.

Does anyone have any idea how I can pass arguments in when running a rule in a Makefile? I want to be able to run the run rule with arguments by typing make run foo bar.

我尝试过，但是没用:

run:
    make compile
    ./scripts/runTrips $1 $2 $PLACES $OUT $VERS

我要提供的参数是第一个和第二个.

The parameters I want supplied are the first and the second.

推荐答案

将参数传递给make命令时，请像对待其他内部make变量一样引用它们.

When passing parameters to a make command, reference them like you would other internal make variables.

如果您的makefile看起来像这样:

If your makefile looks like:

run:
        script $(param1) $(param2)

您可以使用以下语法来调用它:

You can call it with the following syntax:

$> make run param1=20 param2=30

，make应该像这样调用脚本:

and make should call the script like:

script 20 30
