c++环境部署报异常
小白一枚，c++环境部署报异常，请指教：//home/ubuntu/lpr/HyperLPR/build/linux/install/hyperlpr3/lib/libMNN.so: undefined reference to std::_Sp_make_shared_tag::_S_eq(std::type_info const&)@GLIBCXX_3.4.26' //home/ubuntu/lpr/HyperLPR/build/linux/install/hyperlpr3/lib/libMNN.so: undefined reference to log@GLIBC_2.29'

可能是我提供的mnn库在你的计算机上出现依赖版本错误的问题：
- 请把你的系统信息告诉我，我这边尝试排查一下；
- 如果可以建议在你的计算机本地上重新编译一下MNN库，再去替换项目提供的第三方库，MNN请使用2.2.0以上版本：https://github.com/alibaba/MNN/releases

我重新编译了MNN库，目前还有报错：，何解呢？请指教
