Question

我在32位hp Pavilion dv4000笔记本电脑上使用Ubuntu 14.04 LTS。我正在尝试安装OpenCV 2.4.10，但即使遵循了许多教程，我也会遇到同样的错误。当我给“make”命令安装opencv时，终端在17％完成后终止此错误。任何人都可以建议我如何解决它？

尝试以下选项：

使用OpenCV 2.4.9代替
运行sudo apt-get install libv4l-dev

或者使用以下步骤，我已成功使用它在Ubuntu 14.04,12.04和Debian Wheezy中安装OpenCV

sudo apt-get install build-essential make cmake git libgtk2.0-dev pkg-config python python-dev python-numpy libavcodec-dev libavformat-dev libswscale-dev libjpeg-dev libpng-dev libtiff-dev
cd ~/Downloads
git clone https://github.com/itseez/opencv
mv opencv /opt
cd /opt/opencv
git checkout 2.4.10.1 #or whatever version you want
sudo mkdir build
cd build
sudo cmake -j4 -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
sudo make -j4
sudo make -j4 install
sudo ldconfig
