Description

CMake fails to generate when both the contrib-module xfeatures2d and the world module are activated:

CMake Error at cmake/OpenCVUtils.cmake:767 (add_library):
  Cannot find source file:

    C:/3rdparty/OpenCV/build64/modules/xfeatures2d/opencl_kernels_xfeatures2d.cpp

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx
Call Stack (most recent call first):
  cmake/OpenCVModule.cmake:644 (ocv_add_library)
  cmake/OpenCVModule.cmake:631 (_ocv_create_module)
  modules/world/CMakeLists.txt:45 (ocv_create_module)

The error also occurs when OpenCL is disabled

Tried it with the current "3.0.0-beta" tags and it did not work.

Alpha and beta only agree to built perfectly without OpenCL or CUDA functionality.
Can you report back the bugs you are getting?

I get the CMake error mentioned in the above description which results in no build files being generated. Which bugs do you mean?

same here, running the build_framework.py for iOS platform and encountered this error. Disabling world option will let it compile but it will not be able to link the modules after compiling to create an iOS framework. I searched everywhere and this missing header file opencl_kernels_xfeatures2d.hpp is nowhere to be found. This is on the latest github clone.

It is possible to build separate framework for contrib modules:

python ../opencv/platforms/ios/build_framework.py --contrib ../opencv_contrib output_dir

The `world` module does not include contrib modules. There is now separate `contrib_world` module.

I fear that this is not yet finished. Under Windows, the error described in the bug report still persists. Using 'contrib_world' does not fix the problem - as long as 'world' is activated, CMake fails with the same message. The mentioned file does not exist

The mentioned file is auto generated and used only with OpenCL.
Are you sure that bug message is same and it is not about cyclic dependencies? (cmake -G "Visual Studio 11 Win64" -DBUILD_SHARED_LIBS=ON -DBUILD_opencv_world=ON -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -DWITH_OPENCL=OFF ../opencv)

Yes, we experienced the exact same error with Visual Studio 12 Win64 but with OPENCL=ON

Configure step is fine for current master branch:
cmake -G "Visual Studio 11 Win64" -DBUILD_SHARED_LIBS=OFF -DBUILD_opencv_world=ON -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -DWITH_OPENCL=ON ../opencv

Problem is only here:
cmake -G "Visual Studio 11 Win64" -DBUILD_SHARED_LIBS=ON -DBUILD_opencv_world=ON -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -DWITH_OPENCL=OFF ../opencv
but it is another story:

CMake Error: The inter-target dependency graph contains the following strongly connected component (cycle):
  "opencv_world" of type SHARED_LIBRARY
    depends on "opencv_xfeatures2d" (weak)
  "opencv_xfeatures2d" of type SHARED_LIBRARY
    depends on "opencv_world" (weak)
At least one of these targets is not a STATIC_LIBRARY.  Cyclic dependencies are allowed only among static libraries.

Please check again with full cleanup of the build directory (with removing of CMakeCache.txt).
