Here is my blog post on installing OpenCV with it's many dependencies ie Cuda, OpenNI, Gstreamer, ffmpeg, QT5, ... ect. http://drewski1992.blogspot.com/2014/04/install-opencv-24x-with-cuda-55-or-6.html

Following this should give you a full OpenCV build.

Answer 3

thanks for the info. I installed everything in Ubuntu 13.04 and ran into a problem when trying to use the gcv shortcut. Using the

g++ `pkg-config --cflags --libs opencv`

shortcut works perfectly. Previously I had to link all the libraries manually in a Makefile so this is still much better. Appreciate you sharing the info, thanks!

Answer 4

Thanks for the information. I tried to run these commands but encountered several problems. I am using a brand new Ubuntu 12.04 install.

1) The first apt-get remove command asked me if I wanted to remove a lot of things that I wasn't comfortable removing, like LibreOffice. I didn't remove anything in this step, which I figured would be okay, since the only program I've installed is Java SDK and JRE. Why did you opt for such a large list of programs to remove?

2) Adding sudo to the git and tar commands was necessary.

3) When installing opus and ffmpeg, there were many error messages for the ./configure command because of a lack of permission for writing and ultimately the configurations failed.

Anyways, just thought I would log these problems on the post in the hopes that it will improve the procedure listed above.
