I think an upgrade of shapeless to 2.3.0-SNAPSHOT will most likely improve compilation time significantly. Can you give it a try?

[josefstr]

Same with version 2.3.0-SNAPSHOT, after running 45minutes on this simple class I've canceled compilation.

@josefstr can you let me know if this build with your code gives you the same problems? https://github.com/d6y/slickless-issue-5

[josefstr]

this compiled fine.

[d6y]

@josefstr the code is the code you posted --- unless I messed that up --- and compiling it produced a stack overflow exception quite quickly (a few seconds) initially for me.

So we added a -Xss flag to increase the stack size, and that compiles without a stack overflow exception. I can't get long compile times out of this as it stands.

Is there something else to the code you're working with? Or does the increase stack size help you out here?

[d6y]

@josefstr I'll close this ticket, but please re-open if you're still having problems.
