I've found the opencv_cudalegacy. When configure OpenCV, the WITH_CUDA must be enabled.

I had the same problem.

In the file samples/gpu/CMakeLists.txt, the variable OPENCV_CUDA_SAMPLES_REQUIRED_DEP is defined as

SET(OPENCV_CUDA_SAMPLES_REQUIRED_DEPS opencv_core opencv_flann opencv_imgproc opencv_highgui

At the last there is a library named opencv_cudalegacy, but I had searched all cmake files and found not a statement to define a library named as this.

Is this a bug or did I missing something?

I've post it as a issue #3445.

Is this advertisement?

I compiled the current master branch on Linux. I've got the following compiling errors,

CMake Error at /home/xxx/hisstone/opencv/modules/matlab/compile.cmake:47 (message):
  Failed to compile createCalibrateDebevec:
  /home/xxx/hisstone/opencv/build/modules/matlab/src/createCalibrateDebevec.cpp:
  In function ‘void mexFunction(int, mxArray**, int, const mxArray**)’:


  /home/xxx/hisstone/opencv/build/modules/matlab/src/createCalibrateDebevec.cpp:46:3:
  error: ‘Ptr_CalibrateDebevec’ was not declared in this scope

I think there missing a statement befor the mex function,

typedef Ptr<CalibrateDebevec> Ptr_CalibrateDebevec;

But this file is generated by python generator and I don't know how to update it.
