如何在 Windows 上安装 Haskell LDAP？
How to install Haskell LDAP on Windows?
编辑 通过使用 MSYS2 for OpenLDAP 解决
我正在尝试在 Windows 上安装 https://hackage.haskell.org/package/LDAP。
我通过 Cygwin 安装了 OpenLDAP，这些库似乎被引用了，但现在我遇到了这些链接器错误并且不确定缺少什么。谁能解释我做错了什么？如果有某个过程应该有效，我也很乐意开始清理。
运行:
cabal install LDAP --extra-lib-dirs=c:/cygwin64/lib --extra-include-dirs=c:/cygwin64/usr/include
结果：

/u/wrvn on Reddit directed me to MSYS2.
设置和安装 OpenLDAP 包 (package list) 进行得很顺利，尽管确实花费了特别长的时间。
通过将 C:/msys64/mingw64/bin 目录添加到路径和 运行 cabal install LDAP --extra-lib-dirs=c:/msys64/mingw64/lib --extra-include-dirs=c:/msys64/mingw64/include.
安装的 Haskell LDAP 包
路径当然取决于安装位置和体系结构（mingw32 或 mingw64）。
