I try to build the project, doppia, but linking error occurs. I guess this is a linker error, but I've spent a lot of time and haven't find a working answer.
When I tried before, there is no error. But I have other error about CUDA, so I reinstalled opencv. After that, this linking error occurs.
So, I think this is opencv-related problem such as mistake of path, etc.
Command:
cmake -D CMAKE_BUILD_TYPE=RelWithDebInfo . && make
path .bashrc
LD_LIBRARY_PATH=/home/username/Documents/Python/imra/code/opencv-2.4.11/release/lib:/home/username/Documents/Python/imra/code/opencv-2.4.11/release/3rdparty/lib/:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
PKG_CONFIG=$PKG_CONFIG_PATH:/home/matterd/Documents/Python/imra/code/opencv-2.4.11/release/unix-install/
export PKG_CONFIG_PATH
Output
