How do you install MIT AI2 offline in Linux based OS?

Shanmuga_Nathan · June 4, 2022, 1:47pm

Linux & Mac
chmod +x startAIServer.sh (ONLY THE FIRST TIME)
./startAIServer.sh (and go to url: localhost:8888)

tried above, but not launching
output is

TIMAI2 · June 4, 2022, 1:49pm

Are you already using port 8888 for another service? If so you need to change either that or the port AI2 will run on. However, it could be that you already have the Ai2 service up and running, and need to shut that down before starting a new session.

Shanmuga_Nathan · June 4, 2022, 1:50pm

ok will restart my PC and try again

Shanmuga_Nathan · June 4, 2022, 2:01pm

Hurrah!
It works Fine (both Companion and ai2)
But Build server gets this issue

Shanmuga_Nathan · June 4, 2022, 2:32pm

I Figured out that, i saw an option called "Generate YAIL". BUt when I Click then nothing happens.

If this is the issue then someone help me

Shanmuga_Nathan · June 4, 2022, 3:12pm

nothing solved the issue

Peter · June 4, 2022, 3:17pm

As you can see it would be a guessing game if you dont tell anything about your project.

Shanmuga_Nathan · June 4, 2022, 3:21pm

Just inserted check box and button, in order to test the software

TIMAI2 · June 4, 2022, 3:35pm

Does the project compile in proper AI2?

Shanmuga_Nathan · June 4, 2022, 3:46pm

Yes, I just also tried in normal ai2

Peter · June 4, 2022, 3:50pm

I got the same here. hmmmm some testing to do

Shanmuga_Nathan · June 4, 2022, 3:55pm

I hope you come up soon with a solution, and I'm waiting for it

Peter · June 4, 2022, 4:08pm

Strange it has worked before. Something has changed but I don't know what.

Shanmuga_Nathan · June 4, 2022, 4:09pm

Ohh! Ok let's check in next updated version

Ramiro · June 4, 2022, 5:48pm

Parece que esta utilizando la version de java que viene por defecto en linux que es java 11, para que funcione correctamente se debe usar java 8 en su lugar.

java -version

sudo apt-get update

sudo apt-get install openjdk-8-jdk

java -version

sudo update-alternatives --config java

sudo update-alternatives --config javac

Peter · June 4, 2022, 6:07pm

Brainfart. I got this problem in the past but didn´t think about it. I got myself a new laptop some weeks ago and on my old one it was working. Thanks for keeping me away from spending to much time in finding the problem. I hope i will keep it in mind the next time.

Anke · June 4, 2022, 10:30pm

I think we have already discussed this problem (JDK 8 for AI2Offline) extensively, for example here:

Peter · June 4, 2022, 10:59pm

Yes we did thats why i got it wrong. I was thinking that my laptop was running ok. It was the wrong laptop.
