Disclamer: using -nostdcincl isn't possible because it excludes needed system libraries. Here instead the problem seems to be that tthe compiler ignores my -I directives
I have installed a library (OpenCV) in ~/local on a remote machine, since I don't have sudo access there. Notice that an older version of the same library is installed in /usr/local.
I'm trying to compile this code:
g++ -DCC_DISABLE_CUDA -I/home/spm1428/CloudCache -I/home/spm1428/local/include/opencv -I/home/spm1428/local/include/opencv2 -I/usr/include/boost -I/home/spm1428/vlfeat -O3 -g -Wall -c -fopenmp -std=c++11 -c -o Descriptor.o ../Descriptors/Descriptor.cpp
However, the returned error is:
In file included from /usr/local/include/opencv2/opencv.hpp:77:0, from /home/spm1428/CloudCache/Utilities/Utility.hpp:11, from ../Descriptors/Descriptor.cpp:17: /usr/local/include/opencv2/highgui/highgui.hpp:165:25: error: redeclaration of ‘IMREAD_UNCHANGED’ IMREAD_UNCHANGED =-1, ^ In file included from ../Descriptors/Descriptor.cpp:13:0: /home/spm1428/local/include/opencv2/imgcodecs.hpp:65:8: note: previous declaration ‘cv::ImreadModes IMREAD_UNCHANGED’ IMREAD_UNCHANGED = -1, //!< If set, return the loaded image as is (with alpha channel, ^ In file included from /usr/local/include/opencv2/opencv.hpp:77:0, from /home/spm1428/CloudCache/Utilities/Utility.hpp:11, from ../Descriptors/Descriptor.cpp:17: /usr/local/include/opencv2/highgui/highgui.hpp:167:24: error: redeclaration of ‘IMREAD_GRAYSCALE’ IMREAD_GRAYSCALE =0, I think that this happens because there is another version installed. How can I solve this?
I think this error happens for the same reason (the old version doesn't have cv::xfeatures2d::SURF).
