Question

我开始使用scons添加一个新的子目录及其SConscript。但我发现我的SConscript不会被读入根SConscript，我不知道为什么。我错过了什么吗？

我项目中的Scons文件如下：

project-root
 - SConstruct
 - Sconscript
 + supportlib
    - SConscript (returning library target)
    + src
       - ...
 + Program
    - SConsctipt (importing library target)
    + src
       - ...

root的SConscript如下：

subdirs = [..., AAAA]
SConscript(dirs = subdirs, exports='env')

在AAAA子目录中，我有SConscript文件。但是scons实际上并没有在AAAA目录中读取这个SConscript文件。它的日志如下：

scons: Reading SConscript files ...

您的文件树没有显示AAAA文件夹的位置，顶层SConstruct中AAAA的定义也不清楚（是字符串，还是定义为其他？）。这使得无法猜出错误是什么。无论如何，我建议以UserGuide（http://www.scons.org/doc/production/HTML/scons-user.html）的形式查看官方文档，并按照第5章中所述的基本设置进行操作。 14＆＃34;分层构建＆＃34;。

为什么我在scons中定义子目录不起作用？
