Error in installing Open-CV with ffmpeg

Question

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

I followed all instructions found in the InstallationGuide.

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

So I tried to rebuild everything after installing FFMEPG as decribed here.

After configuring installation with the instruction

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

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

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

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

Why is there this library referentiation error?

Answer 1

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.

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

EDIT:

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.
