system :ubuntu1804
gpu: 3060
cuda:cuda11.4
tensorrt:8.4

使用项目tensorrtx 进行yolov5的engine生成， 之前在编译成功的配置为

system :ubuntu1804
gpu: 2060
cuda:cuda10.2
tensorrt:7.2.3.4

换到3060后，make失败，报错
错误：

参考这个issue，将每个报错的函数加了noexcept，再次编译，报错

参考这个issue，发现有个commit，支持tensorrt8

clone最新的后，查看gitlog，发现这个commit

文件修改变化
可以替换，或者 直接切换到这个分支，再次编译，成功！
