This repository contains a conda recipe for automatically building the OpenCV3 Python package and uploading it to our anaconda repository, menpo. This recipe provides builds for Win32, Win64, OSX64 and Linux64 (Ubuntu 12.04 and above).

I have seperated the OpenCV builds from the OpenCV3 builds as OpenCV 2.x and 3.x contain breaking changes between each other. However, note that both OpenCV2 and OpenCV3 install a single cv2 binary module into Python's site-packages, and thus can't actually coexist. Why OpenCV 3.x maintained cv2, rather than moving to cv3, is beyond me, but note this:

YOU CANNOT INSTALL BOTH OPENCV2 AND OPENCV3 AT THE SAME TIME - THEY WILL OVERWRITE EACH OTHER

The automated builds are provided by:

Build Service	Status	Platforms
Travis		Ubuntu 12.04 (x64)
Appveyor		Windows Server 2012 R2 (x86, x64)
Jenkins		OSX 10.10 (x64)

The following OpenCV3 functionality is disabled or unavailable for the automated builds:

TODO

This functionality is disabled in order to attempt to increase the probability that the automated builds will be useful for as large a range of people as possible. I have made no effort to get the FFMPEG/Video builds working. If this is a requirement I can likely remedy it by adding an FFMPEG conda package.

If the lack of this functionality is impeding you, please attempt to build the project yourself by installing conda and following the instructions below:

$ conda install conda-build
$ git clone https://github.com/menpo/conda-opencv3
$ cd conda-opencv3
$ conda config --add channels menpo
$ conda build conda/
$ conda install /PATH/TO/OPENCV3/PACKAGE.tar.gz

If you wish to edit any settings, such as enabling FFMPEG functionality, please edit the build.sh or bld.bat files in order to enable (1) or disable (0) the required settings. Note that in the case where you wish to achieve something like linking an external library, this may be complicated. In this event, I am unable to provide any assistance. The primary reason for providing this package was to attempt to avoid this kind of hassle in the first place!

In the event that you install opencv3 and recieve an error that is not listed below, please create an issue here on Github.

This error stems from the fact that we build on Ubuntu 12.04, which uses GLIBC 2.14. Older versions of Linux use older versions of GLIBC which are not compatible with future versions. If we were to build using an older linux box (or the Linux Standard Base), we could remedy this issue as GLIBC is guaranteed to be backwards compatible. However, the convenience of Travis far outweighs the complexity of this. Therefore, we are currently only able to support GLIBC 2.14 and above. If this is an issue, please rebuild the project manually as described above.
