在ubuntu16上面安裝了HI3536的交叉編譯工具鏈之后，在編譯自己的代碼時報如下的錯誤：
D_FILE_OFFSET_BITS=64 -I../include -g -rdynamic -std=c++11 -o flowdetect_demo ./main.o -lpthread -L../lib -lopencv_highgui -lopencv_imgproc -lopencv_core -lopencv_imgcodecs -lopencv_video -lopencv_videoio -lflowdetect

截圖如下：
這是因為電腦的ubuntu16是64位的，而交叉編譯工具鏈是32位的，解決方法是
sudo apt install lib32z1-dev
