如何使用autotools处理子项目？ [英] How to handle subprojects with autotools?

问题描述

我有一些C ++项目自动工具生成。

I have some C++ project build by autotools.

该项目使用了一些库，也是我写的。库的源作为git的子模块导入到项目中。每个图书馆都有自己的自动工具文件。

The project uses some libraries, also written by me. Source of libraries are imported to the project as submodules of git. Each library has its own autotools files.

说：我有：

src/<my src files>
modules/libfoo/
        libbar/
Makefile.am
Configure.in
<other autotools junk>

我想要的是以某种方式将库包含到主项目编译链中。我想，只包括subdir到Makefile.am是不够的，因为一些检查可以在configure.am中重组。

What I want is to somehow include libraries into main project compilation chain. I guess that just including subdir to Makefile.am is not enough, because some checks can be reformed in configure.am.

推荐答案

您可以通过将 AC_CONFIG_SUBDIRS 命令添加到顶层配置脚本，在子模块中运行配置脚本。它告诉顶级脚本下降到子目录并调用在那里找到的配置脚本。然后，你可以从你的Makefile.am中引用构建的库。

You can run the configure scripts in the sub-modules by adding the AC_CONFIG_SUBDIRS command to the top-level configure script. It tells the top-level script to descend into the sub directories and invoke the configure script found there. Then, you can just reference the built libraries from your Makefile.am.
