错误安装Open-CV的有关ffmpeg [英] Error in installing Open-CV with ffmpeg

问题描述

我试图安装库开CV在Ubuntu 11.04工作。

I am trying to install the library Open-CV working on on Ubuntu 11.04.

我也跟着在 InstallationGuide 。

成功安装后，但我意识到，我因为在我的配置文件 FFMPEG早已不是 FFMPEG 支持是禁用：

However after installing with success I realized that I hadn't FFMPEG support because in my configuration file FFMPEG was disabled:

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

所以我尝试安装FFMEPG的描述下这里后重建一切。

与指令配置安装后

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

我跑make命令得到这个错误：

I ran the make command getting this error:

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

这是汇编，其中误差出来的一点：

This is the point of compilation where the error is coming out:

有谁能够告诉我什么是与安装过程中，我下面这个问题？

can anybody please tell me what's the problem with installation process I'm following?

为什么会出现这个库referentiation错误？

Why is there this library referentiation error?

推荐答案

这些错误是由联动过程中，他们往往意味着你缺少你的系统上的一些库，或者他们在不被搜索的位置构建过程。

These errors are from the linkage process and they often mean that you are missing some libraries on your system, or they are in a location that is not being search by the build process.

我建议你谷歌这些符号知道什么是包，你需要安装。

I suggest you Google these symbols to know what are the packages you need to install.

编辑：

要总结，我们在私下有聊，主要的问题是，X264正在修建静态。 这是必须构建库与共享版 - 使共享。在OP建议添加 - preFIX =的/ usr /本地在所有配置选项

To summarize the chat we had in private, the main issue was that x264 was being built statically. It's essential to build the shared version of the library with --enable-shared. The OP recommends adding --prefix=/usr/local in all configuration options.

这篇关于错误安装Open-CV的有关ffmpeg的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
