我目前正在尝试使用 NixOs 中的 Nix 包管理器安装 dot-net-core-sdk 2.0。

我对 NixOs、Nix、bash 脚本和 ELF 之类的东西都很陌生。但我认为我已经成功地为 dot-net-core-sdk 2.0 创建了有效的 Nix 包描述。

但是，当我尝试创建一个新console项目时，它抱怨找不到控制台模板：

No templates matched the input template name: console.

故事很长...

我已经定义了我的 Nix 包和构建脚本，如下所示：

dotnet-sdk.nix

with import <nixpkgs> {};

stdenv.mkDerivation {
  name = "dotnet-sdk-2.0";

  builder = ./builder.sh;

  libPath = stdenv.lib.makeLibraryPath
    [ lttng-tools kerberos zlib gettext openssl icu libunwind eject stdenv.cc.cc glib ];

  src = fetchurl {
    url = "https://download.microsoft.com/download/1/B/4/1B4DE605-8378-47A5-B01B-2C79D6C55519/dotnet-sdk-2.0.0-linux-x64.tar.gz";
    sha256 = "6059a6f72fb7aa6205ef4b52583e9c041fd128e768870a0fc4a33ed84c98ca6b";
  };
}

构建器.sh

source $stdenv/setup

mkdir -p $out/dotnet-sdk

echo "unpacking $src..."
tar xvfa $src -C $out/dotnet-sdk

echo "unpacking dotnet-sdk..."
p=$out/libexec/dotnet
mkdir -p $out/libexec
mv $out/dotnet-sdk $p

ls -lrth $p

patchelf --interpreter "$(cat $NIX_CC/nix-support/dynamic-linker)" --force-rpath --set-rpath $libPath --debug $p/dotnet

echo "libPath"
echo $libPath

mkdir -p $out/bin
ln -s $p/dotnet $out/bin/dotnet

我可以成功构建包

$ sudo nix-build dotnet-sdk.nix

这会产生一个以以下结尾的长输出

我现在可以在二进制文件上成功执行help和函数，而不会出现有关丢失对象文件的奇怪错误：versiondotnet

$ result/bin/dotnet --version
2.0.0

然而，当我尝试创建新的控制台应用程序时，出现以下错误：

$ /etc/nixos/dotnet-sdk/result/bin/dotnet new console
No templates matched the input template name: console.

Templates      Short Name      Language      Tags
-------------------------------------------------

我不知道为什么它找不到模板，但我有一个弱假设，也许--force-rpath当我在构建脚本中使用 patchelf 修改二进制文件时，我在二进制文件中搞砸了一些东西。

  • 我的包配置和构建脚本看起来没问题吗？ （例如，问题是否与我的 Nix 包描述和构建脚本无关）

  • 我是否缺少一些明显的东西，例如在使用 patchelf 修改二进制文件时以某种方式提供一些辅助网络核心目录的链接？

  • 我还可以做些什么来使 net core sdk 2.0 在 NixOs 中工作？
