*** abort because of serious configure-time warning from Cabal

[MMesch]

probably I am doing something wrong. I often get this error when building with the default.nix that was generated by stack2nix:

*** abort because of serious configure-time warning from Cabal

for example in one case:

   This package indirectly depends on multiple versions of the same package. This is very likely to cause a compile failure.
      package accelerate-llvm-native (accelerate-llvm-native-1.2.0.0-6h9HfY2jTx2VH4bfhr7AT) requires Cabal-2.2.0.1
      package proto-lens-protoc (proto-lens-protoc-0.3.1.0-JlEPGIPhQWg4b89HqVvNBT) requires Cabal-2.2.0.1-302vnEvwKg

Usually the version is the same. I had the same warning with a bunch of other packes, e.g. mtl, text, parsec, stm, which I managed to fix by adding:

in compiler.override {
  overrides = self: super: builtins.intersectAttrs super {
          mtl = null;
          text = null;
          stm = null;
          parsec = null;
          llvm-hs = super.llvm-hs.override { llvm-config = pkgs.llvm_5; };
      };
  initialPackages = stackPackages;
  configurationCommon = { ... }: self: super: {};
  compilerConfig = self: super: {};
}

I would like to understand why this happens and how it can be best avoided. Unfortunately I can't share my whole package to reproduce this. Do you have any idea what this is all about?

In this particular case it's overriding Cabal package with GHC core package Cabal. nulling is should help.

[MMesch]

yea, nulling works! Just wanted to make sure if there is a better way. So in general all core packages should be nulled? Could this be done automatically by stack2nix for a specific compiler version? Thanks for your help!

[domenkozar]

This is taken care in https://github.com/input-output-hk/stack2nix/blob/master/src/Stack2nix/Render.hs#L41

To handle this properly, it should be dynamic based on GHC version given, which is what #84 is for.

I'm having this issue trying to install stack2nix itself on macOS 10.14 via nix-env -i stack2nix.

For now best to use it from NixOS 18.09, I'll fix nixpkgs master.

I also just hit this when using stack2nix with a LTS-12 series snapshot.
