无法安装 UVC 驱动程序：“函数‘x’的隐式声明 [-Werror=implicit-function-declaration]”

我正在为我的毕业设计做一个项目，其中涉及使用网络摄像头。我买了一个外置摄像头并尝试为其安装新驱动程序。现在我的集成网络摄像头无法工作。

我的网络摄像头是 Acer 水晶眼。

我已尝试按照以下步骤重新安装 UVC 驱动程序：

git clone git://linuxtv.org/media_build.git
cd media_build
./build

但是我在构建过程中收到以下错误：

如果有人能帮忙我将非常感激因为我没有太多时间来完成这个项目！

您看到的错误是由您使用站点上的 git clone 命令获取的 C++ 源代码引起的。它们有一个固有的错误（隐式函数声明），因此您应该针对该包提交错误报告。您可以尝试Makefile在 gedit 中编辑，或者如果build是 shell 脚本，则编辑它以-Werror=implicit-function-declaration从任何命令中删除。
