Raspberry Pi error

[onnimikki]

Hi,

Very cool project. Am looking to use it with programming assignments that I make for my students.

Question: I'm trying to get it running on a raspberry pi. Neither the snap nor the .deb packages worked, likely because it's an arm processor. So I made it from source. (Clear instructions! Thanks!)

Running one of the examples generates an error:

$ diagon Math -- "1+1/2 + sum(i,0,10) = 112/2"
terminate called after throwing an instance of 'std::system_error'
  what():  Unknown error -1
Aborted

But simple executions like asking for the version is fine:

$ diagon --version
version: 156

Any suggestion as to how to clear up the issue?

thanks!

Hi! Thanks for using Diagon! I would be curious how it get used.

About your issue, I tried today on Desktop. I observed the version build from source worked correctly. However the snap version got the exact same error.

I think you might have used the snap version, because I don't see a ./diagon at the beginning, but diagon.

I will investigate today and get back to you.

I think I understand the issue.

I see this thread referenced the same issue and a fix:
antlr/antlr4#3418 (comment)

I understand the problem, and I even proposed a fix in ANTLR:
antlr/antlr4#4086

But, I though the fix was already merged ;-)
I will downgrade the ANTLR version for you, and push for the fix to land.

I landed the fix and update:
b2bf80f

I pushed the new version into the stable release of the snap package:

This should be automatic, but you can refresh it using:

sudo snap refresh diagon

Could you please let me know if your issue has been fixed?
