GNU默认情况下保持静音 [英] GNU Make silent by default

问题描述

默认情况下是否可以从Makefile内部抑制命令回显?

Is it possible to suppress command echoing by default from within the Makefile?

我知道在--silent模式下运行make会做到这一点，就像在每个命令前面加上@一样.

I know that running make in --silent mode will do it, as will prefixing every command with @.

我正在寻找命令或节，我可以在Makefile中包含 ，从而省去了用@乱扔一切或让用户手动使一切静音的麻烦.

I'm looking for a command or stanza I can include inside the Makefile, saving the trouble of littering everything with @ or having the user silence everything manually.

推荐答案

如果定义目标.SILENT:，则make将不会回显任何内容.通常最好保护定义，因此您可以轻松地将其关闭:

If you define the target .SILENT:, then make will not echo anything. It's usually best to guard the definition, so you can easily turn it off:

ifndef VERBOSE
.SILENT:
endif

现在默认情况下，make将不打印任何内容，但是如果您运行make VERBOSE=1，它将打印.

Now by default, make will print nothing, but if you run make VERBOSE=1, it will print.

请注意，尽管手册中的声明声称.SILENT已过时-如果得到适当的保护，它通常比@好得多(更有用，更灵活).

Note that despite the statement in the manual claiming that .SILENT is obsolete -- if properly guarded, it is generally much better (more useful and flexible) than @.

.SILENT目标不应成为Makefile上的第一个目标，否则make将默认使用它.

The .SILENT target should not be the first on your Makefile, otherwise make will use it by default.
