我正在使用 Ubuntu 14.04，OpenCV 3.0.0，这是安装后尝试使用我的 opencv 库的命令和错误列表
linaro@linaro-nano:~/opencv/samples/cpp$ ./cpp-example-facedetect lena.jpg
This program demonstrates the cascade recognizer. Now you can use Haar or LBP features.
This classifier can recognize many kinds of rigid objects, once the appropriate classifier is trained.
It's most known use is for faces.
Usage:
./facedetect [--cascade=<cascade_path> this is the primary trained classifier such as frontal face]
[--nested-cascade[=nested_cascade_path this an optional secondary classifier such as eyes]]
[--scale=<image scale greater or equal to 1, try 1.3 for example>]
[--try-flip]
[filename|camera_index]
see facedetect.cmd for one call:
./facedetect --cascade="../../data/haarcascades/haarcascade_frontalface_alt.xml" --nested-cascade="../../data/haarcascades/haarcascade_eye.xml" --scale=1.3
During execution:
Hit any key to quit.

我从一开始就无法安装 libgtk2.0-dev，但我想我可以使用 aptitude 而不是 apt-get 来强制安装它
答案1
从您的输出中我看到的错误是：
E：无法找到软件包 libpango1-dev
没有名为的包libpango1-dev，而是libpango1.0-dev
要安装libpango1.0-dev，请使用：
sudo apt-get install libpango1.0-dev`
答案2
运行命令
sudo apt-get -f install
sudo apt-get install libgtk2.0-dev libpango1.0-dev libcairo2-dev libfontconfig1-dev
它将安装损坏的依赖项并尝试此操作关联
编辑：尝试这个命令
sudo aptitude install libpango1.0-0=1.29.3+git20110916-0ubuntu1 plymouth-x11=0.8.2-2ubuntu28 libpango1.0-dev=1.29.3+git20110916-0ubuntu1 gir1.2-pango-1.0=1.29.3+git20110916-0ubuntu1
希望它能起作用
