Hi,
I am new to eclipse and opencv and I was trying to build a sample c++ code using Eclipse.
I have installed following packages. rpm -qa | grep opencv opencv-devel-3.4.4-10.fc30.x86_64 opencv-3.4.4-10.fc30x86_64 opencv-core-3.4.4-10.fc30.x86_64 opencv-contrib-3.4.4-10.fc30x86_64

$ locate opencv_core.so.3.4 /usr/lib64/libopencv_core.so.3.4 /usr/lib64/libopencv_core.so.3.4.4
I have already added /usr/lib64/ and /usr/lib/ as library search paths in eclipse.
Is there anything missing in my config?

I haven't done this in a while, but there were some changes to bash environment I seem to remember. Either LIBRARY_PATH or LD_LIBRARY_PATH or something similar. I've completely rebuilt my system since then, so I don't have the old bashrc to check. But the opencv stuff documents it on their webpage I think.
