Re: [Haskell-cafe] Cabal: Can only one processor core be used?

Let's also mention that there's work to have a single semaphore which governs the concurrency in a better way which allows the tooling to dynamically decide how many cores to use for compiling a package when multiple of them are being compiled.

Hi,

There is -j flag for this: https://cabal.readthedocs.io/en/3.4/cabal-project.html#cfg-field-jobs

Hi

I've searched the web and the cabal user guide on how to use more processor cores for compilation via cabal. I couldn't find anything.

It looks like only one processor core can be used with cabal, even though (I've read on the web) GHC supports parallel compilation.

Cabal compilation times can be a pain. It can't be that you can use only one processor core with cabal, can it ..?
