c - 使用ffmpeg安装Open-CV出错

Question

我正在尝试安装在 Ubuntu 11.04 上运行的库 Open-CV。

我遵循了 InstallationGuide 中的所有说明.

但是在安装成功后我意识到我没有FFMPEG支持因为在我的配置文件中FFMPEG被禁用了:

Video I/O: 
--     DC1394 1.x:                 NO 
--     DC1394 2.x:                 YES 
--     FFMPEG:                     NO 
--       codec:                    YES 
--       format:                   YES 
--       util:                     YES 
--       swscale:                  NO 
--       gentoo-style:             YES 
--     GStreamer:                  YES 
--     UniCap:                     NO 
--     PvAPI:                      NO 
--     V4L/V4L2:                   Using libv4l 
--     Xine:                       NO

所以我按照描述安装 FFMEPG 后尝试重建所有内容 here .

按照说明配置安装后

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ../OpenCV-2.3.1

我运行 make 命令得到了这个错误:

make[2]: *** [bin/opencv_test_calib3d] Error 1
make[1]: *** [modules/calib3d/CMakeFiles/opencv_test_calib3d.dir/all] Error 2
make: *** [all] Error 2

这是错误出现的编译点:

任何人都可以告诉我我正在执行的安装过程有什么问题吗？

为什么会出现这个库引用错误？

Answer 1

这些错误来自链接过程，它们通常意味着您在系统中缺少某些库，或者它们位于构建过程未搜索的位置。

我建议您谷歌这些符号以了解您需要安装的包是什么。

总结一下我们的私下聊天，主要问题是 x264 是静态构建的。 使用--enable-shared 构建库的共享版本是必不可少的。 OP 建议在所有配置选项中添加 --prefix=/usr/local。
