Posso adicionar o pacote libasound2 ao repositório NixOS?

Question

Ao tentar criar meu projeto, descubro que estou perdendo a biblioteca asound .

O meu problema corresponde ao da esta thread, onde o problema foi resolvido instalando o pacote debian libasound2 listado aqui .

Estou executando NixOS e não vejo o pacote libasound2 disponível para instalação via nix-env .

Existe alguma outra maneira que eu possa instalar a dependência? Pode ser adicionado à lista de pacotes do NixOS? Se sim, como vou fazer isso?

Minha compilação de projeto usa stack de Haskell e o comando $ stack build . A saída completa é mostrada abaixo.

$ stack build

    Cabal-simple_mPHDZzAJ_1.24.2.0_ghc-8.0.2: Missing dependency on a foreign
    library:
    * Missing C library: asound
    This problem can usually be solved by installing the system package that
    provides this library (you may need the "-dev" version). If the library is
    already installed but in a non-standard location then you can use the flags
    --extra-include-dirs= and --extra-lib-dirs= to specify where it is.

Foi sugerido nos comentários que eu instalei alsaLib . Eu tentei isso usando nix-env executando o comando $ nix-env -iA nixos.alsaLib . Esta tentativa não funcionou (eu corri para o mesmo erro * Missing C library: asound ao tentar construir seguindo este nix-env install).

    

Answer 1

Eu tenho o projeto para construir colocando o seguinte em stack.yaml .

nix:
  packages: [alsaLib]
