我在ubuntu 12.10上，我想安装OpenCV。
我正在关注this website上的教程，当我尝试第二步时，意思是
sudo apt-get install build-essential checkinstall git cmake libfaac-dev libjack-jackd2-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libsdl1.2-dev libtheora-dev libva-dev libvdpau-dev libvorbis-dev libx11-dev libxfixes-dev libxvidcore-dev texi2html yasm zlib1g-dev
我收到以下错误消息：
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
libsdl1.2-dev : Depends: libpulse-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我不知道这意味着什么以及如何解决它。
答案 0 :(得分：0)
该消息表示您正在尝试安装需要libsdl1.2-dev的{{1}}，但无法安装。也许apt无法在任何软件包存储库中找到libpulse-dev。
