安装带有ffmpeg的Open-CV时出错

Question

我正在尝试安装在Ubuntu 11.04上运行的Open-CV库。

我遵循了InstallationGuide中的所有说明。

然而，在成功安装后，我意识到我没有FFMPEG支持，因为在我的配置文件中禁用了FFMPEG：

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

所以我试着在安装FFMEPG作为描述的here之后重建所有的东西。

使用说明配置安装后

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命令得到以下错误：

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：

有人能告诉我我正在进行的安装过程有什么问题吗？

为什么会有这个库引用错误？

Answer 1

这些错误来自链接过程，它们通常意味着您的系统上缺少某些库，或者它们位于构建过程未搜索到的位置。

我建议你在谷歌上搜索这些符号，以了解你需要安装哪些包。

编辑：

总结我们私下的谈话，主要的问题是x264是静态构建的。使用--enable-shared构建库的共享版本是非常必要的。OP建议在所有配置选项中添加--prefix=/usr/local。
