我已经尝试了看似无穷无尽的方法来stack build引用图书馆secp256k1-haskell，但无济于事。

这是我的.cabal文件-

cabal-version:       >=1.10
name:                testproj
version:             0.1.0.0
license:             BSD3
license-file:        LICENSE
author:              XXXX
maintainer:          XXXX@gmail.com
build-type:          Simple
extra-source-files:  CHANGELOG.md

library
  exposed-modules:     Addr
  build-depends:       base
                     , secp256k1-haskell
  hs-source-dirs:      src
  default-language:    Haskell2010

我在 Windows 环境中，并设法libsecp256k1.dll从.netNuget 包中获取了一个版本。我尝试将以下行添加到我的.cabal文件中也无济于事 -

  extra-lib-dirs:      lib
  extra-libraries:     libsecp256k1

希望得到一些帮助。谢谢 - 我今晚花了很多时间试图让它发挥作用。

这是构建输出 -

不是很修复——但我最终选择简单地安装并从那里进行开发libsecp256k1。WSL2发现该环境比尝试在 Windows 上进行开发更加用户友好且易于设置。
