Simple C++ pub/sub app in tutorial not working

[flyotlin]

Hi guys, I ran into some problems and hope if it's a right place to ask question here.

I followed the tutorial to write a simple pub/sub app in C++, but as I opened up both pub and sub from different terminals, none of which starts doing what they're supposed to do.

I ran my app in a docker container on Macbook Air M1 (macOS BigSur v11.6.2).

The docker container base image is Docker Fast DDS 2.6.0.

Is there any hints or thoughts on this problem? Anything would be appreciated!

Some Updates:
I tried a clean installation from binaries in another Ubuntu 21.04 computer, and followed the tutorial exactly the same as the above.

It turned out working well, maybe the problem's related to Docker Image or M1 Macbook Air.

As stated in the Docker for Apple documentation:

In summary, running Intel-based containers on Arm-based machines should be regarded as “best effort” only.
We recommend running arm64 containers on Apple silicon machines whenever possible

The docker image for Fast DDS is Intel-based, so there may be issues when running it on Apple silicon.
