编辑使用MSYS2 for OpenLDAP解决

我尝试在Windows上安装https://hackage.haskell.org/package/LDAP。

我通过Cygwin安装了OpenLDAP，并且这些库似乎被引用，但现在我收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？如果某个过程应该有效，我也很乐意开始干净。

运行：

cabal install LDAP --extra-lib-dirs=c:/cygwin64/lib --extra-include-dirs=c:/cygwin64/usr/include

结果：

/u/wrvn指示我MSYS2。

设置并安装OpenLDAP软件包（package list）进展顺利，但确实花费了相当长的时间。

通过将C:/msys64/mingw64/bin目录添加到路径并运行cabal install LDAP --extra-lib-dirs=c:/msys64/mingw64/lib --extra-include-dirs=c:/msys64/mingw64/include来安装Haskell LDAP软件包。

路径当然取决于安装位置和架构（mingw32或mingw64）。

如何在Windows上安装Haskell LDAP？
