Description (last modified by ryandesign (Ryan Carsten Schmidt))

I wanted to install an old version of opencv (2.3.1a) so that I did the following. 

svn co -r 86729 http://svn.macports.org/repository/macports/trunk/dports/graphics/opencv
cd opencv/
sudo port -v install +apache2+postgresql83

Then I got errors in the middle: 

...
Command failed:  cd "/opt/local/var/macports/build/_Users_tkim2_Packages_opencv/opencv/work/OpenCV-2.3.1" && /usr/bin/make -j2 -w all 
Exit code: 2
Error: org.macports.build for port opencv returned: command execution failed
...

The more details in the attachment.

The log you attached was not from a ​clean build, but errors I see in it appear to relate to ffmpeg: 

error: ‘av_open_input_file’ was not declared in this scope

This old version of opencv is probably not compatible with the new version of ffmpeg we have in MacPorts. You could try installing a correspondingly older version of ffmpeg too.
