最小哈斯克爾（GHC）程序安裝（部署，而無需GHC /小集團）

Question

（我的問題是有關分發二進制程序不哈斯克爾平臺，GHC，小集團，...）

我需要部署一個良好的陰謀形成哈斯克爾應用（一個Yesod腳手架），但我有磁盤空間限制。

GHC大小約爲1Gbytes，存儲所有陰謀的源代碼，包等...需要更多的磁盤空間，等等

顯然，哈斯克爾平臺，GHC，......是關於發展（不部署）。

在我的特定情況下，我可以生成

cabal clean && cabal configure && cabal build 

，併成功地運行（有些像）

./dist/build/MyEntryPoint/MyEntryPoint arg arg arg 

但是，這個依賴？如何將其移動到生產環境？ （我的「dist」彙編）

我可以把沒有cabal的二進制依賴嗎？怎麼樣？

非常感謝！

默認情況下，ghc使用Haskell庫的靜態鏈接。所以生成的二進制文件獨立於Haskell生態系統。如果你的程序不需要任何數據文件，剛剛走出從./dist/build/MyEntryPoint/MyEntryPoint複製二進制到主機

如果您也有通過使用數據路徑的二進制引用的數據文件（例如模板，圖片，靜態的HTML頁面）發現驚天動地的邏輯，你可以使用Setup copy如下（使用快樂爲例）：

如果你不想安裝到/usr/local然後傳遞所需的前綴Setup configure。

如果目標主機在其他方面類似（安裝了相同版本的C庫（如gmp和ffi）），則此方法運行良好。如果您還需要靜態鏈接某個C庫，請參閱hammar在其評論中鏈接的question。
