我正在尝试使用Haskell外部函数接口，我遇到了一些麻烦;即，一旦我尝试使用外部依赖项（在这种情况下来自text包中的Data.Text），GHC就无法将我的二进制文件与对包的未定义引用链接起来。我做错了什么或者是否需要添加一些标志以使GHC链接依赖？
当我尝试手动将~/.cabal/lib/x86_64-linux-ghc-8.0.1/text-1.2.2.1-9Yh8rJoh8fO2JMLWffT3Qs/libHStext-1.2.2.1-9Yh8rJoh8fO2JMLWffT3Qs.a添加到OBJECTS列表时，构建失败仍然缺少bytestring的引用，text的依赖关系。

我通过在链接命令中添加-package text来解决这个问题。您也可以通过将原始.hs文件放在link命令中而不是单独构建来解决它。
