Question

我在raspberry pi上使用opencv和python，所以根据互联网上的教程，我需要V4L2驱动程序。我按照本教程安装了驱动程序https://www.ics.com/blog/raspberry-pi-camera-module#.VAaCHqM0_YQ

然而，当我编译时，我得到了这个错误。我不知道问题是什么，从来没有遇到过这个问题。我该如何解决。感谢。

自此问题发布以来，2年多以来，这些行号有所改变。在Raspberry Pi 2或经典Pi上使用Raspbian 7 Wheezy可能很容易产生更多错误。

对网页进行的一项更正是，最好运行./bootstrap.sh而不是autoreconf。我还写libjpeg-dev以避免过于具体libjpeg62-dev的依赖性问题。然后构建和安装今天在Raspbian 9 Stretch（gcc 6.3）上工作正常：

sudo apt-get install autoconf gettext libtool libjpeg-dev
git clone git://git.linuxtv.org/v4l-utils.git
cd v4l-utils
./bootstrap.sh
./configure
make
sudo make install
