SuperDirt segfaults when starting server

Questions and Answers

Hi,

Recently discovered tidal and trying to install it. I think I got everything right except one thing: When I launch the superdirt server as said in the docs, by running sclang startup.scd, I get this log and then it segfaults. Any idea why this is happenning ?

What happens if you just run sclang or scide?

When running sclang, I get this message, and then it seems to read from stdin, but not doing anything.

I don't have installed scide

Now try running SuperDirt.start as per the docs:
