在ubuntu 11.10中编译opencv2.3.1 [英] compile opencv2.3.1 in ubuntu 11.10

问题描述

这是我遵循的教程： http://thebitbangtheory.wordpress.com/2011/10/23/how-to-install-opencv-2-3-1-在ubuntu-11-10-oneiric-ocelot-with-python-support /

我认为问题是ffmpeg，我使用的版本是0.8.10，我安装在/ usr并启用了共享，但是当我遵守opencv时，输出的文件已经满了

Here is the tutorial I followed:http://thebitbangtheory.wordpress.com/2011/10/23/how-to-install-opencv-2-3-1-in-ubuntu-11-10-oneiric-ocelot-with-python-support/
I think the problem is ffmpeg, the version I used is 0.8.10, and I installed it in /usr and enabled share, but when I complied opencv,the output was full of

./../ lib / libopencv_highgui.so。 2.3.1：未定义的引用 av_codec_get_id'
../../lib/libopencv_highgui.so.2.3.1：未定义的引用 av_seek_frame'

../../lib/libopencv_highgui.so.2.3.1：未定义的引用`avpicture_get_size

./../lib/libopencv_highgui.so.2.3.1: undefined reference to av_codec_get_id' ../../lib/libopencv_highgui.so.2.3.1: undefined reference toav_seek_frame'
../../lib/libopencv_highgui.so.2.3.1: undefined reference to `avpicture_get_size

推荐答案

感谢@karlphillip和@ Appleman1234，我终于解决了我的问题。关键是删除包含cmake信息的/ release目录，并从头开始重新编译，即mkdir ./release，cd ./release，cmake，make和make install。 BTW，ffmpeg是0.8 +，我的是0.8.1。

Thanks to @karlphillip and @Appleman1234, and I solved my problem finally. The key is remove the /release directory that contains the cmake information and do the recompile from scratch, i.e. mkdir ./release, cd ./release, cmake, make and make install. BTW,ffmpeg is required 0.8+,and mine is 0.8.1.
