Question

我正在研究USB CDC串行，以便通过SAMA5D36开发板发送和接收数据。我需要将我创建的标头集成到代码中。

我可以将自己的标头和.c文件添加到make文件中吗？我在下面给出make文件的文本。在此make文件中的添加位置令人困惑。

首先阅读documentation of GNU make。然后阅读有关Invoking GCC和documentation of the ld linker的信息（因为make和Makefile可能会调用它们）。

您可能想添加（适当地，在您的Makefile中）：

一些INCLUDES += -I some-includedir-path 行
some LIB_PATH += -L some-libdir-path 行，
并增加LIBS =行。

添加这些内容的位置很重要。

请不要忘记检查您在法律上是否可以更改该Makefile。因此，请研究其许可或版权（可能在您的律师的帮助下）。我想您可以，但我不是律师（您可能会研究open source licenses ...）

顺便说一句，您可以使用remake（带有标志-x）来调试Makefile
