Cabal fetches an old plutus-core version to compile

[albertodvp]

Hi, I've been trying to setup a very simple and minimal environment to compile Plutus scripts using plutus-tx.

I'm using haskell.nix and I followed the README but for some reason cabal is trying to compile plutus-core-lib-plutus-core-1.7.0.0 which I suspect is an "old" version (from what I see from https://chap.intersectmbo.org/).

Here is the error I get:

warning: Git tree '/home/albertodvp/Projects/plutus-playground' is dirty
error: builder for '/nix/store/c70cypp031sgpcymsdvap7glg33s5lwc-plutus-core-lib-plutus-core-1.7.0.0.drv' failed with exit code 1;

What am I be doing wrong?

Here is my experiment: https://github.com/albertodvp/plutus-playground

Try using constraints: plutus-core > 1.7 in your cabal.project and cabal will probably tell you.

Ok, thanks to your hint I managed to understand what I was missing: I forced a higher version using constraints: plutus-core > 1.7 and I discovered I was missing libblst-any. I think the easier thing to do is using the iohk-nix overlays, that actually allows me to compile.

Thank you!
