I am new to Ubuntu and to Opencv. On attempting to install OpenCV-2.4.3 on Ubuntu 11.10 i get this :

 user@user-ThinkPad-T510:~/OpenCV-2.4.3$  cmake -D CMAKE_BUILD_TYPE=RELEASE 
            -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON

CMake Error:

The path to the source directory:
/home/user/OpenCV-2.4.3/BUILD_PYTHON_SUPPORT=ON

contains unsupported character '='.

Please use a different source directory name. Am i doing it wrong???

The last parameter of cmake command must be path to root CMakeLists.txt file. You need to create build folder, i.e. build and run from there:

$cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_PYTHON_SUPPORT=ON ..

Try to remove the space after the several -D

Like this:

-DBUILD_PYTHON_SUPPORT=ON

I had a similar problem to yours, and this worked. Have no idea why, though.
