Inform 7 V10.1.1 Compile Error

“Property given twice in the same declaration” Error.

I’ve installed the recently available V10.1.1 for Windows. Most games I’ve created compile okay but getting an error on my recent WIP. I’ve no idea what is causing it, it is only using two extensions and both have worked okay in other games I’ve tried to compile. Can anyone help?

what version of Patrollers are you using? Could you provide a google drive link or similar, or copy it to a .txt file and attach it to a reply here please?

I’m using V12, which I’ve attached.

Do you create a property called “etc” in your story? Can you show us the code involving its declaration from your source? And what are the lines around line number 28329 in your auto.inf ?

Got it! I have nothing declared as “etc” in the game but I have got one particular variable with a long name. Shorted it and the game now compiles. Thanks for the help, never thought about looking in the auto.inf.

That is worth reporting as a bug, though, if it hasn’t been already. Issues like overly long variable names should give you an informative problem message instead of crashing at the I6 level.

I’ll have a go at logging it.
