No momento, estou tentando instalar o dot-net-core-sdk 2.0 com o gerenciador de pacotes Nix no NixOs.
Sou muito novo em ambos os NixOs, Nix, bash scripting e coisas como ELF. No entanto, acho que consegui criar uma descrição de pacote Nix válida para o dot-net-core-sdk 2.0.
No entanto, quando tento criar um novo projeto console , ele reclama que não consegue encontrar o modelo de console:
No templates matched the input template name: console.
Eu defini meu pacote Nix e construo o script da seguinte forma:
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";
};
}
builder.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
Eu posso criar o pacote com sucesso com
$ sudo nix-build dotnet-sdk.nix
Que resulta em uma saída longa que termina com
...
unpacking dotnet-sdk...

Agora posso executar com êxito as funções help e version no binário dotnet sem erros estranhos sobre arquivos de objetos ausentes:
$ result/bin/dotnet --version
2.0.0
No entanto , quando tento criar um novo aplicativo de console, recebo o seguinte erro:
$ /etc/nixos/dotnet-sdk/result/bin/dotnet new console
No templates matched the input template name: console.
Templates Short Name Language Tags
-------------------------------------------------
Eu não tenho idéia de por que ele não pode encontrar os templates, mas eu tenho uma hipótese fraca de que talvez eu estraguei alguma coisa no binário usando --force-rpath quando modifico o binário com patchelf no buildscript.
A configuração do meu pacote e o buildscript estão corretos? (por exemplo, é o problema não relacionado à descrição do meu pacote Nix e ao nosso script)
Existe algo óbvio que estou perdendo, como de alguma forma fornecer um link para alguns dos diretórios do núcleo da rede auxiliar ao modificar o binário com patchelf?
Outra coisa que eu posso fazer para fazer o net core sdk 2.0 funcionar no NixOs?
