最小哈斯克尔（GHC）程序安装（部署，而无需GHC /小集团）

Question

（我的问题是有关分发二进制程序不哈斯克尔平台，GHC，小集团，...）

我需要部署一个良好的阴谋形成哈斯克尔应用（一个Yesod脚手架），但我有磁盘空间限制。

GHC大小约为1Gbytes，存储所有阴谋的源代码，包等...需要更多的磁盘空间，等等

显然，哈斯克尔平台，GHC，......是关于发展（不部署）。

在我的特定情况下，我可以生成

cabal clean && cabal configure && cabal build 

，并成功地运行（有些像）

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

但是，这个依赖？如何将其移动到生产环境？ （我的“dist”汇编）

我可以把没有cabal的二进制依赖吗？怎么样？

非常感谢！

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。如果你的程序不需要任何数据文件，刚刚走出从./dist/build/MyEntryPoint/MyEntryPoint复制二进制到主机

如果您也有通过使用数据路径的二进制引用的数据文件（例如模板，图片，静态的HTML页面）发现惊天动地的逻辑，你可以使用Setup copy如下（使用快乐为例）：

如果你不想安装到/usr/local然后传递所需的前缀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（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question。
