Re: [Nix-dev] How to intall llvm-3.9.0 API for ocaml-4.0.3?

2016-11-04 Thread Vincent Laporte 
Hi,

So as to override the ocaml-llvm derivation to change the llvm version,
you can write something like:

ocamlPackages_4_03.llvm.override { llvm = llvm_38; }

This works with llvm-3.8. Unfortunately for you, it does not work with
llvm-3.9; indeed, the build process of llvm has changed so that the
ocaml-llvm derivation cannot be used as is. You may need to write your
own derivation, maybe looking at the llvm-3.9 derivation. If you
succeed, please share your findings.

Cheers,

Hi Jose,

Try to override OCaml package instead:

environment.systemPackages = with pkgs; [
  ocamlPackages.llvm.override { llvm = llvm_39; };
];

[Nix-dev] How to intall llvm-3.9.0 API for ocaml-4.0.3?

2016-11-03 Thread José Romildo Malaquias 
Hello.

I want to install the latest LLVM bindings (3.9.0) for the OCaml
programming language (4.0.3) on my NixOS unstable system.

Currently I have the following on my system configuration:

  nixpkgs.config.packageOverrides = pkgs: rec {
# ...
ocamlPackages = pkgs.ocamlPackages_latest;# 4.0.3 currently
llvmPackages = pkgs.llvmPackages_39;  # latest
  };

  environment.systemPackages = with pkgs; [
# ...
llvmPackages.llvm
ocamlPackages.llvm
  };

This gives me ocaml-llvm-3.7.1.

How can get ocaml-llvm-3.9.0?

Romildo
