Running qt gui app in docker container for R-car h3 board

Since you copy files into the image, no one will be able to build your Dockerfile.
Please share the error from the build log as well.

Furthermore, I formatted your post, as you used a quote block, instead of a code block.


Please, format your post according to the following guide: How to format your forum posts
In short: please, use </> button to share codes, terminal outputs, error messages or anything that can contain special characters which would be interpreted by the MarkDown filter. Use the preview feature to make sure your text is formatted as you would expect it and check your post after you have sent it so you can still fix it.

Example code block:

```
echo "I am a code."
echo "An athletic one, and I wanna run."
```
