在 ubuntu 14.04 LTS 中安装 opencv 2.4.10 时出现未定义的引用错误

Question

我在我的 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，但即使在学习了很多教程之后，我也会遇到同样的错误。当我给出 "make" 命令来安装 opencv 时，终端在完成 17% 后终止并出现此错误。谁能建议我如何解决它？

Answer 1

尝试以下选项：

改用 OpenCV 2.4.9
运行 sudo apt-get install libv4l-dev

或使用以下步骤，我已成功使用这些步骤在 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
