Exception: sbt.TrapExitSecurityException

[drom]

Fresh git clone. Running sbt run getting this error:

Any guidance how to fix?

Can someone help with this?

We'll need a little more context to help here:

• what is the host system

• which version of sbt is installed

• have you created a design in scala with a main method

I assume this is "chisel" (chisel2 as opposed to chisel3). In either case

% sbt run

without a user created design will fail and is not the correct way to use chisel.

If you are just starting out, we strongly suggest you start with chisel3 https://github.com/ucb-bar/chisel3. Start with the tutorial https://github.com/ucb-bar/chisel-tutorial, then use template https://github.com/ucb-bar/chisel-template to create a basic chisel project.

There is documentation in the associated GitHub wikis to help you get started.

If you really do want to use chisel2, we suggest you check out the chisel2 branch of the tutorial https://github.com/ucb-bar/chisel-tutorial/tree/chisel2 and verify that it executes in your environment.
