Cmake build error OpenCV 3.4.0

edit

Hi

After installing ffmpeg on my Ubuntu 16.04 system, i decided to rebuild Opencv with ffmpeg, however i am getting build errors, that I do not have the knowledge to understand.

command:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_EXAMPLES=ON -D WITH_FFMPEG=ON -D WITH_V4L=ON -D WITH_OPENGL=ON -D WITH_CUDA=ON -D CUDA_ARCH_BIN="3.0 5.0 6.1" -D WITH_CUBLAS=ON -D WITH_CUFFT=ON -D WITH_EIGEN=ON -D CMAKE_INSTALL_PREFIX=/usr/local ..

then:

make all -j8

Then it stops at 47%, and I do not understand what is going wrong..:
