Opencv_contrib: Error while "Built target opencv_saliency_pch_dephelp"

[McVilla]

I've installed tesseract before, and it's failed to build target opencv text pch dephelp.

cmake -D  CMAKE_BUILD_TYPE=RELEASE -D OPENCV_EXTRA_MODULES_PATH=~/OpenCV/opencv-3.3.0/opencv_contrib-3.3.0/modules -D INSTALL_C_EXAMPLES=OFF -D CMAKE_INSTALL_PREFIX=/usr/local**

[alalek]

Try to disable precompiled headers support via "-DENABLE_PRECOMPILED_HEADERS=OFF" CMake option.

[McVilla]

I tried, but it doesn't work. The Error: cannot support c++ 2011 still exists.

[alalek]

Try to force C++11 compilation mode: -DCMAKE_CXX_FLAGS=-std=c++11

[McVilla]

Thanks so much!

I am also facing the same issue.

[LaurentBerger]

@alalek have you seen PR#1337

[tamersalama]

Slightly off-topic; but this manifests itself as various errors, e.g.: make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2.
if using brew - you can edit the formula (e.g:brew edit opencv) and adding @alalek flag might fix the issue.
