如何在gnumake文件中强制错误 [英] How to force an error in a gnumake file

问题描述

我想在我的Makefile中检测到工具版本错误的情况，并通过错误消息(指示该项目不是正确的版本)来强制Make失败.

I want to detect a condition in my makefile where a tool is the wrong version and force the make to fail with an error message indicating the item is not the right version.

有人可以举一个例子吗?

Can anyone give an example of doing this?

我尝试了以下操作，但语法不正确:

I tried the following but it is not the right syntax:

ifeq "$(shell svnversion --version | sed s/[^0-9\.]*://)" "1.4"
$error("Bad svnversion v1.4, please install v1.6")
endif

谢谢.

推荐答案

来自手册:

$(error Bad svn version v1.4, please install v1.6)

这将导致make出现致命错误:

This will result make to a fatal error:

$ make
Makefile:2: *** Bad svn version v1.4, please install v1.6.  Stop.
