Target runner returning NULL

[Lucas Guilhon]

Hello!

I'm trying to execute my target runner as a Julia script but for some reason it fails when I do a scenario check, and succeeds when I run the command manually.

Here's a screenshot to show what I mean:

I could send more information/files if needed. 

Thanks in advance!

HI,

Could you send your scenario.txt file? Which version of irace is this?

I would suggest to start with a simpler dummy script. Something that simply prints a number without including any files or calling any other function. If that doesn't work, then the problem could be in the environment that irace uses to call julia versus the environment of your shell. Otherwise, if it does work, then the problem is in your julia script.

Also, why do you need to do run(`echo $res`)? Why not simply println(res) ?

Best wishes,

Manuel.
