Undefined libraries when cross compiling application

C++

Hello all,

I want to cross compile an openCV application for an ARMs target running linux. I think i finally managed to crosscompile the libraries. When compiling the application i have to reference all the libraries. I then get a bunch of “undefinied refrence” errors within the libs. I only will copy a section of the terminal output since its a lot.

This is my command:

/home/apc1wi/Documents/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-g++ test.cpp -o test_EVAL -I /usr/local/include/opencv4 -L/home/apc1wi/Documents/opencv_crosscompile/opencv-4.x/build/lib/ -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_objdetect -lopencv_videoio -lopencv_dnn -lopencv_calib3d -lopencv_imgcodecs -lopencv_features2d -lopencv_flann

and this is the output
