in my lib folder, now i am compilin it using
g++ main.cpp -I/home/matulmat/local/include/opencv4/ -L/home/matulmat/local/lib /home/matulmat/local/lib/*.so.*
and it compiles, but running it with
./a.out
returns
./a.out: error while loading shared libraries: libopencv_core.so.4.1: cannot open shared object file: No such file or directory
... but file libopencv_core.so.4.1 is in directory!. I tried linkin it usin -l
g++ main.cpp -I/home/matulmat/local/include/opencv4/ -L/home/matulmat/local/lib -lopencv_core -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc -lopencv_core.so.4.1
but it returned
cannot find -llibopencv_core.so.4.1
.. Why is this happeningg? How can i fix it? It seems its impossible to make openCV work...
Thanks for help!
