最小的haskell（ghc）程序安装（没有ghc / cabal的部署）
（我的问题是关于分发没有haskell-platform，ghc，cabal等的二进制文件）
我需要部署一个良好的组合式haskell应用程序（一个Yesod脚手架），但我有磁盘空间限制。
GHC的大小约为1G，存储所有的cabal源代码，软件包等等......需要更多的磁盘空间等等......
显然，haskell-platform，ghc ......是关于开发（而不是部署）的。
在我的具体情况下，我可以生成
cabal clean && cabal configure && cabal build
并成功运行（有些人喜欢）
./dist/build/MyEntryPoint/MyEntryPoint arg arg arg
但是，依赖关系呢，如何将其转移到生产环境？ （我的“dist”汇编）
我可以放置二进制依赖没有cabal？ 怎么样？
非常感谢你！
默认情况下，ghc使用Haskell库的静态链接。 所以生成的二进制文件独立于Haskell生态系统。 如果您的程序不需要任何数据文件，只需将./dist/build/MyEntryPoint/MyEntryPoint的二进制文件复制到主机
如果您还有使用Cabal的数据路径查找逻辑由二进制文件引用的数据文件（例如模板，图像，静态html页面），则可以按如下方式使用Setup copy （使用happy作为示例）：
/tmp/happy-1.18.10 $ ./Setup configure Warning: defaultUserHooks in Setup script is deprecated. Configuring happy-1.18.10... /tmp/happy-1.18.10 $ ./Setup build Building happy-1.18.10...

如果您不想安装到/usr/local则将所需的前缀传递给Setup configure 。
如果目标主机在其他方面类似（安装了相同版本的C库（例如gmp和ffi）），则此方法运行良好。 如果您还需要静态链接某个C库，请参阅hammar在其评论中链接的问题。
