make -j Error with yolov5

Hi, after successfully converting my yolov5s model to onnx I ran into the following error message when trying to run the "make" command:

skymind@skymind:~/yolov5-tensorrt-linghu/yolov5/build$ make -j

Any help or suggestion in solving this would be highly appreciated. Thanks you.

@abuelgasimsaadeldin Hi, I met the same issue. (make -j Error with yolov4, to be exact) I think the file libyaml-cpp.a was created on the device different from yours. So, I've tryed to create the static library file on my device. (I tryed sudo apt install libyaml-cpp-dev, but it haven't work well.)

git clone https://github.com/jbeder/yaml-cpp.git
cd yaml-cpp
mkdir build
cd build
cmake ..
make -j

After these commands, I've replaced the file tensorrt_inference/common/includes/yaml-cpp/libs/libyaml-cpp.a and the directory tensorrt_inference/common/includes/yaml-cpp/include/yaml-cpp with the file yaml-cpp/build/libyaml-cpp.a(created now) and the directory yaml-cpp/include/yaml-cpp. Then the make -j command went through.
