When I follow the instruction in Git and type

cmake -DOPENCV_EXTRA_MODULES_PATH=<opencv_contrib>/modules -D CMAKE_INSTALL_PREFIX=/usr/local ..

it reported

Python error: <stdin> is a directory, cannot continue
Python error: <stdin> is a directory, cannot continue
Python error: <stdin> is a directory, cannot continue
CMake Error at modules/python/CMakeLists.txt:78 (set_target_properties):
  set_target_properties called with incorrect number of arguments.

the set_target_properties in the file was used as:
set_target_properties(${the_module} PROPERTIES
                      LIBRARY_OUTPUT_DIRECTORY  "${LIBRARY_OUTPUT_PATH}/${MODULE_INSTALL_SUBDIR}"
                      PREFIX ""
                      OUTPUT_NAME cv2
                      SUFFIX ${CVPY_SUFFIX})

I also tried to move the modules in opencv_contrib to opencv and install them , but xfeature2d, matlab,python,cvv failed even though the other modules succeed being installed.

Can anyone tell me what I need to change or correct? Thanks

Okay some problems I see at the moment

there is a typo between -D and OPENCV_EXTRA_MODULES_PATH, a missing space
you need to replace <opencv_contrib> with the location of your contrib folder. Mainly it is something like ../../opencv_contrib/modules/ assuming you are in the build folder inside your opencv branch.

Can you check if this fixes the problem?

Thank you for your information. Now some modules can be installed, but the modules: xfeature2d, matlab,python,cvv still failed installing.

And you used the latest master branch? Python and xf2d were fixed there. Matlab bindings i havent build yet!

I've tried the latest version. I find that the modules can be installed in the release folder, but I still don't find the corresponding folder in my opencv_source_directory. When I want to use cv2.SURF, it still says that ' AttributeError: 'module' object has no attribute 'SURF''. Can you help me more about it? Thank you!

Okay let me wrap some stuff up

You start by downloading the sourcecode for both opencv and opencv_contrib repository. Make sure they are in a common folder, to make stuff easier.
Inisde the opencv folder, you make a new folder called build
Now move into that folder and run there your CMAKE command

Making sure that you used the above configuration

The build directory will be ../build/ which means, just use the folder where you are now. In detail the .. means go up one folder, then look for the build folder, but you are already in it.
For the -DOPENCV_EXTRA_MODULES_PATH you will pass ../../opencv_contrib/modules/ which means, go 2 levels up into the common install folder of both opencv and opencv_contrib repo, then go into opencv_contrib and then into modules folder

Now run the make -j 5 command! Everything should install just fine now!

I am facing an issue in this regard, I have installed cmake yet it throws a 'command not found' error. Also, what is the path to be given for <opencv_source_directory> ??
