多个目标的构建后步骤 [英] Post-build step for multiple targets

问题描述

我有一个makefile，它有多个目标，可以输出不同格式的数据，例如制作html ，制作pdf ，制作txt 等.这些选项被使用.我已经对构建前步骤进行了排序，但是不确定如何使构建后步骤正常运行.

I have a makefile that has multiple targets for outputting data in different formats, e.g. make html, make pdf, make txt etc. and I would like to have pre-build and post-build steps that run when any of these options are used. I have the pre-build step sorted, but not sure how I can get the post-build step working properly.

.PHONY: html pdf txt pre-build post-build

pre-build:
    do-pre-build-stuff

post-build:
    do-post-build-stuff

html: data.dat
    generate-html data.dat

pdf: data.dat
    generate-pdf data.dat

txt: data.dat
    generate-txt data.dat

data.dat: pre-build
    generate-some-data > data.dat

如何使 post-build 步骤在每个目标之后运行?

How can I get the post-build step to run after every target?

推荐答案

不幸的是，您必须为每个规则编写不同的规则.但是您可以使用静态模式规则使其更简单:

You have to write a different rule for each one, unfortunately. But you can make it simpler with a static pattern rule:

html pdf txt: %: real-%
        do-post-build-stuff

real-html: data.dat
        generate-html data.dat

real-pdf: data.dat
        generate-pdf data.dat

real-txt: data.dat
        generate-txt data.dat

这将根据 real-版本创建目标 html ， pdf 和 txt . real-版本完成实际工作，然后在完成后，将后构建内容作为基本目标中的配方完成( html ， pdf和 txt ).

This creates targets html, pdf, and txt which depend on the real- versions. The real- versions do the actual work, then after they're done the post-build stuff is done as a recipe in the base target (html, pdf, and txt).

这条规则只是一个速记，因此您不必全部写下来；结果是相同的:

That rule is just a shorthand so you don't have to write it all out; the result is identical:

html: real-html
        do-post-build-stuff

pdf: real-pdf
        do-post-build-stuff

txt: real-txt
        do-post-build-stuff
