Hello,

The code that builds well in tensorRT 7.1.3 is
tensorRT 8.0.1 gives the following error:

How can we solve this problem?

/usr/include/aarch64-linux-gnu/NvInferRuntimeCommon.h:1222:18: error: overriding ‘virtual void nvinfer1::ILogger::log(nvinfer1::ILogger::Severity, const AsciiChar*) noexcept’
virtual void log(Severity severity, AsciiChar const* msg) noexcept = 0;

Thank you.

Hi,

The ILogger API has slightly changed in TensorRT 8.0.
Please update it with a similar way as below:

#include "logger.h"
...
sample::Logger logger;
nvinfer1::IRuntime* runtime = nvinfer1::createInferRuntime(logger);
...

Thanks.

Hello,

Which file do I have to modify?

Thank you.

Hi,

Would you mind sharing the source of your app with us?
So we can check it for you?

Thanks.

Hello,

It’s an open source.
URL: tensorrt_inference/yolov5 at master · linghu8812/tensorrt_inference · GitHub

I am getting the above error when building this project.
Can you please check what the problem is?
The method I found through the forum is at the URL below.

It seems to be a temporary solution, can you find a more fundamental solution?

Thank you.

Hi,

Please try to apply the following changes:

Can you tell me how to resolve these errors?

Thank you.

Dear @Hodu,
Have you applied the changes given in #7. Also, could you make changes to Logger class varaibles in common.h same as in common.hpp(like use sample::Logger instead of Logger, use sample::LogStreamConsumer instead of LogStreamConsumer etc) and confirm if it helps?
