nimforum mirror - Error compiling Rosencrantz with --gc:arc

I'm eager to try out --gc:arc in a project and tried compiling Rosencrantz using it and I'm getting:


$ nimble server
  Executing task server in /home/boisvert/git/rosencrantz/rosencrantz.nimble

(I changed the local nim.cfg to --threads:on --gc:arc)

What does this Error: system module needs: nimDestroyAndDispose error mean? Is it a compiler issue or a code-to-be-compiled issue?

thanks!

PS: I'm using the latest devel branch installed with choosenim

It means your setup is broken and the new Nim picks up an old stdlib.

Any tips on how to fix my broken setup? My PATH is clean, only pointing to ~/git/Nim/bin, I've also wiped my ~/.cache/ directory.

How could nim pick up an old stdlib? What should I look for?

thanks!

Try completely removing your installation and installing Nim with choosenim. It will show what needs to be added to PATH during installation.

I tried with a fresh Docker container, base Ubuntu image 18.04.3 LTS, install git, install gcc, install choosenim, install nim #devel using choosenim, git checkout of rosencrantz, update nim.cfg with --gc:arc and --threads:on, run nimble server, same result.

I highly doubt this is due to a broken local nim setup. This is reproductible with a clean environment.
