问题1

加载so库文件失败，原因是没有配置环境变量

解决方案：添加环境变量
1.修改/etc/profile文件，在文件尾部添加

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/software/back/HIK_ISUP_SDK/lib:/home/software/back/HIK_ISUP_SDK/lib/HCAapSDKCom

2.调用 source /etc/profile 命令使配置生效
3.修改/etc/ld.so.conf文件，在文件尾部添加

/home/software/back/HIK_ISUP_SDK/lib
/home/software/back/HIK_ISUP_SDK/lib/HCAapSDKCom

4.调用 ldconfig 命令使配置生效
