我正在尝试使用arduino-core和arduino-mk软件包在Raspbian上编译DumpFile example。
它通常适用于其他项目，但是当涉及到使用SD库时，我在编译时遇到错误，我不知道是不是我做错了，或者它是SD库本身的问题。< / p>
从我的changelog of the arduino-core软件包中，在我的软件包版本和最新版本之间没有修复SD库。所以升级可能没有帮助。
我正在复制运行＆gt; make

有人可以帮我指出这个问题吗？

请注意，SD库有一个子目录，其中包含未定义的函数。也许您需要在make中添加-I / usr / share / arduino / libraries / SD / utility
