The new commit in gama-headless.sh stops gama-headless server in GAMA 1.9 for Mac M1

[xiaofanliang]

Hi, I am a Mac M1 user, using the Monterey system. I am on GAMA 1.9.

I was recently struggling with not being able to start game-headless server in GAMA 1.9 (alpha version). It turns out the solution is for me to revert this commit gama-platform/gama@240559e. A friend commented that the realpath is a Linux syntax that is not available in Mac.

So to solve my problem, in my local version of the gama-headless.sh, I changed if ! "$( dirname $( realpath "${BASH_SOURCE[0]}" ) )" back to the previous commit if ! "$( dirname "${BASH_SOURCE[0]}" )"

Then I am able to start gama-headless server with GAMA 1.9.

If you want to see more details of this issue, you can see in this issue in gama_client.js Github repo. There are more screenshots and contexts there.

Note that, the other developer @hqnghi88 did mention that it works on his Mac M1 computer, so I am puzzled.

Just to complete this issue this is the message I have when trying to run GAMA1.9 Headless from Mac M1

And what @xiaofanliang suggests is working.

@RoiArthurB and @hqnghi88 any chance to commit this change so we can retry with the latest build?

I'm installing MacOS Monterey, but I think to remember that it was working fine on Ventura... 👀

@RoiArthurB Is it possible to update the gama.headless for the Mac Os Monterey so we don't have to change it by hand when trying to run headless with the last release 1.9?
