linux - Arduino SD 库 arduino-core 1 :1. 0.0.1+dfsg-7 未定义引用

Question

我正在尝试编译 DumpFile example在 Raspbian 上使用 arduino-core 和 arduino-mk 包。

它通常在其他项目中运行良好，但是当涉及到使用 SD 库时，我在编译时出现错误，我不知道是我做错了什么还是 SD 库本身的问题。

来自changelog of the arduino-core包，在我的包版本和最新版本之间，SD 库中没有任何固定内容。因此升级可能无济于事。

我正在复制运行 >make

的输出

有人可以帮我查明问题所在吗？

谢谢

注意 SD 库有一个包含未定义函数的子目录。也许你需要添加 -I/usr/share/arduino/libraries/SD/utility 到你的 make
