Question

我使用CODEO（Eclipse + overlay）为ELinOS RTOS构建应用程序。事实是，我失去了使用eclipse CDT自动生成Makefile的能力，我生成了一个通用的Makefile。

我没有输入这个巨大的Makefile（很多很多的包含和源目录），而是尝试使用addprefix patsubst和一些wildcard，但这并没有成功，主要是因为我吮吸通用makefile！

关于图书馆，只使用了少数图书馆，所以我会手工编写。

以下是我的代码的结构。

Top directory
|
---> common ---> inc/
|                src/
---> pack_AAA ---> comp_AAA ---> inc/
|            |                   src/
|            ----> comp_AAB ---> inc/
|                                src/
---> comp_BBB ---> inc/
|                  src/
---> main.cpp

我只想枚举热门文件夹（common，pack_AAA，comp_BBB等等，主要是因为不是每个TOP文件夹都必须编译，我的{ {1}}位于其中一个顶级文件夹中）。下面是可变数量的子目录。叶子总是Makefile（。hpp文件）和inc/（如你所猜，.cpp文件）文件夹。

此外，TOP文件夹的数量不会改变，所以我介意声明它们，但子文件夹会。

对象文件可以在任何他们想要的位置（单独的顶级src/目录，在build/ ...内），只要生成的可执行文件，我们称之为src/即可在顶级目录

提前致谢！

这是我必须以

这是我最终的Makefile。我不得不隐藏组件名称。
