【问题描述】：

正在阅读包裹清单...完成构建依赖树
读取状态信息...完成某些软件包无法安装。这可能意味着您有请求不可能的情况，或者如果您使用的是不稳定的一些必需的包尚未创建的分发或被移出 Incoming。以下信息可能有助于解决这种情况：

The following packages have unmet dependencies:
 libopencv-dev : Depends: libopencv-objdetect-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libopencv-highgui-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libopencv-legacy-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libopencv-contrib-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libopencv-videostab-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libopencv-superres-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libopencv-ocl-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libcv-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libhighgui-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
                 Depends: libcvaux-dev (= 2.4.8+dfsg1-2ubuntu1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

另外，我使用了“aptitude install libopencv-dev”，但它不起作用。所以我不知道如何完成这个问题。

【问题讨论】：

那些库看起来也很过时（cv,cvaux 是 opencv1.0 的东西，而不是 2.4.x）。最好从 github (2.4.11) 获取 src 并编译它。

标签： c++ opencv ubuntu apt-get

【解决方案1】：

我需要 OpenCV 3.2 并需要启用硬件加速模块，我在 ubuntu 14.04.5 上遵循了这个过程：

下载所需的库：

sudo apt-get install
  build-essential \
  cmake \
  git \
  libgtk2.0-dev \
  pkg-config \
  libavcodec-dev \
  libavformat-dev \
  libswscale-dev \
  python-dev \
  python-numpy \
  libtbb2 \
  libtbb-dev \
  libjpeg-dev \
  libpng-dev \
  libtiff-dev \
  libjasper-dev \
  libdc1394-22-dev

download opencv
解压，cd到目录下运行：

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=OFF -D WITH_OPENGL=ON -D WITH_OPENCL=ON -D WITH_VA_INTEL=ON -D BUILD_SHARED_LIBS=ON ..

make -j8 #to run 8 different jobs in parallel

sudo make install

add the line "export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH" to the .bashrc file

sudo ldconfig

希望对你有帮助

【解决方案2】：

官方repos中的包已经过时了，不要使用它们。这是我用来安装 OpenCV 的，应该也适合你。

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
