使用指令编译
1、编译成可执行文件
编译指令：
***/toolchainbin/arm-linux-gnueabihf-g++ -o test main.cpp ****.cpp *****.cpp -I ./include -I ./include/opencv -I ./include/opencv2 -L ./lib -lncnn -lopencv_core -lopencv_imgcodecs -lopencv_imgproc -lopencv_videoio -lopencv_ml -std=c++11 -pthread -fopenmp
2、编译算法库
编译指令：
****/toolchainbin/arm-linux-gnueabihf-g++ ***.cpp ****.cpp -fPIC -shared -Wl,-soname,libWindNetPredictClass.so -o libWindNetPredictClass.so.0.1 -I ./include -I ./include/opencv -I ./include/opencv2 -L ./lib -lncnn -lopencv_core -lopencv_imgcodecs -lopencv_imgproc -lopencv_videoio -lopencv_ml -std=c++11 -pthread -fopenmp
