Compiling OpenCV with Contrib and C++11 Support?

Question

I want to compile opencv from source on ubuntu 16.04. I already did this successfully a couple of times before. I am following this tutorial from pyimagesearch. Normally this works very well, but this time I am getting the following error for the contrib module text.

[ 27%] Generating precomp.hpp.gch/opencv_text_RELEASE.gch In file

included from /usr/include/c++/5/cinttypes:35:0,

[ 27%] Built target pch_Generate_opencv_saliency

Does somebody know how to resolve this?

Adding -D ENABLE_PRECOMPILED_HEADERS=OFF \ to CMake command resolved the issue.

Complete CMake Command:

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D INSTALL_C_EXAMPLES=OFF \
    -D OPENCV_EXTRA_MODULES_PATH=~/github/opencv_contrib-3.2.0/modules \
    -D PYTHON_EXECUTABLE=~/.virtualenvs/cv/bin/python \
    -D ENABLE_PRECOMPILED_HEADERS=OFF \
    -D BUILD_EXAMPLES=ON ..
