Mat*_*teo 3 c opencv ffmpeg makefile cmake
我正在尝试在Ubuntu 11.04上安装Open-CV库.
我按照InstallationGuide中的所有说明进行操作.
但是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

所以我尝试在安装FFMEPG之后重建所有内容,如此处所述.
使用该指令配置安装后
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ../OpenCV-2.3.1

我运行make命令得到这个错误:
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关注的安装过程有什么问题?
为什么会出现这个库引用错误?
这些错误来自链接过程,它们通常意味着您缺少系统上的某些库,或者它们位于构建过程未搜索的位置.
我建议您使用Google这些符号来了解您需要安装的软件包.
编辑:
总结我们私下进行的聊天,主要问题是x264是静态构建的.这是必须构建库的共享版本用--enable-shared
.OP建议添加--prefix=/usr/local
所有配置选项.
