I have Opencv 3.4.3 installed on my Raspberry Pi. When I try to compile a simple C++ script with "g++ -std=c++0x -o runnable removeRedEyes.cpp pkg-config --libs --cflags opencv" it throws me the error given below. Opencv built succesfully without error. What woulde be the cause?

Thanks.

how, exactly ? are there any previous opencv versions on your box ?

pkg-config

try to avoid that, since you can't control / see what is going on.

No, there aint any opencv installed. I have no idea why it throws this error.
