How to overlay "rec" in a package

Alan01252 · January 18, 2022, 7:52am

Hi all,

I’m trying to update the dotnet-sdk to the latest version available due to a bug fix. I’ve done a few overlays before but the usage of “rec” in default.nix in this package is causing my mind to melt.

If I want to override the packages there in my configuration.nix how would I go about doing so?
Is it even possible?

The hashes are all easily retrievable as the maintainers have handily included this script

github.com

NixOS/nixpkgs/blob/5aaed40d22f0d9376330b6fa413223435ad6fee5/pkgs/development/compilers/dotnet/print-hashes.sh

#!/usr/bin/env nix-shell
#!nix-shell -i bash -p curl

set -eu

if [[ $# -lt 1 ]]; then
    echo \"usage: $0 version\" >&2
    exit 1
fi

VERSION=$1
HASHFILE=$(mktemp /tmp/dotnet.hashes.XXXXXXXX)
trap "rm -f $HASHFILE" EXIT

curl -L https://dotnetcli.blob.core.windows.net/dotnet/checksums/$VERSION-sha.txt -o $HASHFILE

ASPNETCORE_VERSION=$(grep aspnetcore-runtime- $HASHFILE | grep -- -linux-x64.tar.gz | tail -n -1 | sed -e 's:.*aspnetcore-runtime-::' -e 's:-linux-x64.tar.gz.*$::' )
ASPNETCORE_HASH_LINUX_X64=$(grep aspnetcore-runtime- $HASHFILE | grep -- -linux-x64.tar.gz | cut -d ' ' -f 1)
ASPNETCORE_HASH_LINUX_ARM64=$(grep aspnetcore-runtime- $HASHFILE | grep -- -linux-arm64.tar.gz | cut -d ' ' -f 1)
ASPNETCORE_HASH_OSX_X64=$(grep aspnetcore-runtime- $HASHFILE | grep -- -osx-x64.tar.gz | cut -d ' ' -f 1)

Thanks!

This is warping my mind even more. I tried just copying the three files and using these as an overlay.

This “works” apart from I get this message

anonymous function at /nix/store/02x581j37dsnny0warlqlrdplc57y010-source/overlays/dotnet/build-dotnet.nix:7:1 called without required argument ‘lttng-ust_2_12’

I have no idea how to pass this argument in?

self: super:
{
  dotnetLatest = super.callPackage  ./dotnet {};

}

The overlay simply looks like that, with dotnet package simply updating the hashes in the “rec” portion of the code.

lttng-ust_2_12 should be among the top-level attributes in Nixpkgs (pkgs). Make sure you have fresh enough Nixpkgs version.
