I am trying to compile OpenCV library on a shared drive on my system. I was able to configure and generate makefiles successfully by using these settings, but when i try to compile I get the following error:

Linking CXX shared library ../../lib/libopencv_core.so
CMake Error: cmake_symlink_library: System Error: Operation not permitted
CMake Error: cmake_symlink_library: System Error: Operation not permitted
make[2]: *** [lib/libopencv_core.so.2.4.3] Error 1
make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2
make: *** [all] Error 2

Please help to resolve. I think it may be an issue with the mount flags.

This happens, because vfat type filesystems don't support symlinks. Mount flags won't change this situation.

I'm not familiar with CMake, but I suppose you are using some kind of rule in your makefile that is telling CMake to make a symbolic link to lib/libopencv_core.so.2.4.3, which fails.

will it be possible if I ntfs system ? I need a file system which is compatible with windows also. –  bubble Jan 4 '13 at 9:43
    
Well, try to mount your ntfs drive, then create a file inside and then execute the following command in your terminal: ln -s /path-to-ntfs-drive/name-of-file /path-to-ntfs-drive/symlink-name. If this works without an error, then I suppose you will be able to run CMake on ntfs drive. If you get an error, then verify that your drive is mounted via ntfs-3g driver (mount will say that type is fuseblk). –  bender Jan 4 '13 at 12:27
