如何在qmake生成的Makefile中添加自定义目标? [英] How to add custom targets in a qmake generated Makefile?

问题描述

我使用qmake生成Makefile，并且效果很好.但是，有时我想在生成的Makefile中添加更多内容，而不必编辑生成的Makefile.

I use qmake to generate the Makefile, and that works well. However, sometimes I want to add more stuff to the generated Makefile without having to edit the generated Makefile.

假设我们在源代码旁边有一个Doxygen目录，我需要在其中运行一些doxygen命令来生成文档.因此，最好在主Makefile中将此作为目标.但是作为默认qmake，它不了解这种类型的额外内容.

Let's say that we beside the source code have a Doxygen directory, and there I need to run some doxygen commands to generate the documentation. So it would be nice to have this as a target in the main Makefile. But as default qmake do not understand this type of extra stuff.

所以我可以添加一些内容告诉qmake在"doxygen"目录中包含辅助Makefile，或者直接在qmake配置中添加额外目标"吗?

So can I add something to tell qmake to include a secondary Makefile in the "doxygen" dir, or maybe add "extra targets" directly in the qmake config?

也许是这样的:

推荐答案

这是一个老问题，但是我还是会添加一个答案.

This is an old question, but I'll add an answer anyway.

虽然qmake中似乎似乎不普遍支持自定义规则，但假设使用GNU make，有一种简单的方法可以做到这一点.只需创建一个名为makefile的文件(全部小写):

While there seems to be no general support for custom rules in qmake, there is a simple way to do it, assuming GNU make. Just create a file called makefile (all lower case):

include Makefile

re: clean
        $(MAKE) all

最后两行是我的自定义规则.

where the last two lines are my custom rule.

如果两者都存在，GNU make将使用makefile而不是Makefile.

GNU make will use makefile, not Makefile, if both exist.

顺便说一句，re规则解决了"make -j8 clean all"的问题.该命令将在完成清理之前开始执行所有操作. re规则可确保顺序性.

BTW, the re rule solves the problem with "make -j8 clean all". This command will start doing all before it has finished doing clean. The re rules guarantees sequentiality.
