【问题描述】：
我真的需要在 arch linux 上安装 libi2c-dev 以使用 I2C 库，我将使用该库来读取和写入 Cubieboard 2 上的 I2C 端口。
PACMAN 上不存在该软件包。
如果没有安装 libi2c-dev，当我编译我的代码和我希望使用的库时，我会收到以下编译器错误消息。

我需要： 1. 想办法在arch linux上安装libi2c-dev，或者 2.获取头文件I2C-DEV.H并手动#include到我的项目文件夹中。
【问题讨论】：
-
com_serial,failcount 函数的定义在哪里？ libi2c-dev中没有这个函数的定义
-
基本上，我正在关注本教程：linux-sunxi.org/I2Cdev#Configuring_your_FEX 它声明应该安装 libi2c-dev。当然，我不能在 libi2c-dev 的 i2c-dev.h 文件中定义任何定义。
-
好的，所以您只需要 i2cdev 包或其文件？
-
你解决了吗？如果是，则在答案中提出解决方案。
