engine is not launched after running example 'hello world' code

[akzing-hz]

By following the guide here https://docs.zetane.com/getting_started.html#installation, I created a scripy to run the 'hello world' code. However, the engine was not launched but keep printing "Dialing Zetane"

OS: Ubuntu 18.04
Zetane 1.7.0

Console output:

Dialing Zetane...

Hi, you could try manually launching the Zetane Viewer before running the script.

/opt/zetane/Zetane --server

If the viewer doesn't launch, you could share the output of ldd /opt/zetane/Zetane

Thanks for the quick reply. Still doesn't launch, the output is below:

Thank you. That seems ok. There are a few things we could try:

• Check if the graphics drivers are installed (gpu drivers or Mesa apt install libgl1).
• Here's an example Dockerfile showing minimal Zetane setup: https://www.notion.so/zetane/Containerized-Zetane-Viewer-7b77ec2b545148a0bf15f861d280eb1b
• Try an older release.

[akzing-hz]

I've checked the gpu driver version as shown below.

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 418.43       Driver Version: 418.43       CUDA Version: 10.1     |
|-------------------------------+----------------------+----------------------+

I've also tried mannually installed the Zetane-1.7.0.deb, xdg-utils, firefox packages according to the following script, but still doesn't work.

FROM nvidia/opengl:base
ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update && apt-get install -y libgl1 wget

ENV ZTN_DEB=Zetane-1.7.0.deb
RUN wget https://download.zetane.com/zetane/$ZTN_DEB \
  && apt-get install -y ./$ZTN_DEB \
  && rm -rf ./$ZTN_DEB

# To open help URLs (optional)
RUN apt install -y xdg-utils firefox

There is an Aborted(core dumped) error when running /opt/zetane/Zetane --server in Version 1.6.2

[konafah]

It sounds like there is an environment difference that we can't reproduce on our end. It might be an untested locale (echo $LANG) or a networking issue preventing connection to our licensing server.

We're adding increased startup diagnostics in an upcoming release. I'll keep you posted here when it becomes available.

[akzing-hz]

Thanks. I also doubt that there may be a networking issue as my host is behind a proxy. BTW, the local is en_US.UTF-8
