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:

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
).
