Is it possible to run opencv (python binding) from a virtualenv?

Question

I would like to keep everything contained within the virtualenv. Is this possible with OpenCV? I\'m fine with building from scratch, do I just need to setup the virtualenv

Answer 1

From opencv install guide :

By default the OpenCV build system will choose the most recent version of Python that it can find, or you can force it to use a specific version using the PYTHON_EXECUTABLE variable when you invoke cmake.)

I just installed it on my ubuntu 11.10, on virtual env --with-no-site-package, by following the instruction on the link above. you need to build whole opencv. and its python wrapper together.

EDIT 1:

1. Create a temporary directory, which we denote as , where you want to put the generated Makefiles, project files as well the object files and output binaries.

   cd ~/opencv
   mkdir release
   cd release
   cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
   

2. Enter the created temporary directory () and proceed with:

   make
   sudo make install
   

---------

after build & install add the extension modules on PYTHON_PATH

export PYTHONPATH=~/projects/opencv/release/lib:$PYTHONPATH
