Compiling OpenCV 3.3 : C++11 is not supported
I finally compile OpenCV 3.3
from source successfully, however I still don't know why it wouldn't compile before. All what I had modified is the flag OPENCV_EXTRA_MODULES_PATH
to the reference where the source files of the modules of opencv_contrib 3.3.0
are, like so:
$ cmake \
-D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_CUDA=ON \
-D ENABLE_FAST_MATH=1 \
-D CUDA_FAST_MATH=1 \
-D WITH_CUBLAS=1 \
-D INSTALL_C_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D OPENCV_EXTRA_MODULES_PATH=/home/jhros/opencv-3.3.0/opencv_contrib-3.3.0/modules \
-D BUILD_SHARED_LIBS=ON \
-D WITH_GTK=ON \
-D BUILD_EXAMPLES=ON ..
I got an infinite number of warnings of kind (and many others):
warning: dynamic exception specifications are deprecated in C++11
And also you might get an error with newer version of GCC
which is not supported by cuda:
#error -- unsupported GNU version! gcc versions later than 5 are not supported!
But this could be solved by setting cmake
to use older version of GCC
while compiling OpenCV
CMAKE_C_COMPILER=/usr/bin/gcc-5
I installed OpenCV 3.3.1 on Linux Mint 18.2, followed this article (https://www.learnopencv.com/install-opencv3-on-ubuntu/) and I had the same problem. I changed cmake command from
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_C_EXAMPLES=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D WITH_TBB=ON \
-D WITH_V4L=ON \
-D WITH_QT=ON \
-D WITH_OPENGL=ON \
-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
-D BUILD_EXAMPLES=ON ..
to
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_C_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=OFF \
-D WITH_TBB=ON \
-D WITH_V4L=ON \
-D WITH_QT=ON \
-D WITH_OPENGL=ON \
-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
-D BUILD_EXAMPLES=OFF ..
(changed from -D CMAKE_INSTALL_PREFIX=/usr/local \
to -DCMAKE_INSTALL_PREFIX=/usr/local \
) and it worked for me. Hope useful.
Note: 3.3.0 is not work.
(Sorry about my English)
i also had this error, and add argument OPENCV_EXTRA_MODULES_PATH
point to the opencv_contrib solved it
