在Ubuntu 11.10的opencv安装

Question

我想在Ubuntu11.10上使用终端安装OpenCV。但它给了我以下错误。我一直无法解决它。注意最后四行。

Answer 1

对于这样的错误：

dpkg: error processing /var/cache/apt/archives/AAA (--unpack): 
trying to overwrite `/usr/lib/BBB', which is also in package CCC 
dpkg-deb: subprocess paste killed by signal (Broken pipe) 
Errors were encountered while processing: 
AAA 
E: Sub-process /usr/bin/dpkg returned an error code (1) 

（其中AAA，BBB，CCC是占位符名称，如果它是不明确）

做

sudo dpkg -i --force-overwrite AAA 

（给出AAA的完整路径），然后运行

sudo apt-get -f install 

再次。

而且，在发布问题前尝试使用Google搜索，导致有大量链接解释如何解决此错误！
