It seems I have to add sentences like "${DARKNET_PATH}/src/image_opencv.cpp" in "CMakeLists.txt" "image_opencv.cpp" should be the cpp.file contain the function like "pull_implicit_layer"

I solve this problem. I make yolov4 with darknet_ros. It is because AlexAB added [empty]/[silence] and [implicit] layers on 12 May and from the history i know new files called "representation_layer.h" and "representation_layer.c" were created so I have to add ${DARKNET_PATH}/src/representation_layer.c in CMakefile.list

Does this issue occur with the most recent version of this repo?

This was my problem as well after I updated some of the code for v4 as well.

This still works for the latest darkent. Thanks!
