Question

我尝试安装Haskell软件包＆＃34;从任何地方调用haskell＆＃34;我收到以下错误消息：

cabal.exe: Missing dependency on a foreign library:
* Missing C library: HSrts-ghc8.0.1
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
cabal: Leaving directory 'C:\Users\Manfred\AppData\Local\Temp\cabal-tmp-2460\call-haskell-from-anything-1.0.1.0'
cabal: Error: some packages failed to install:
call-haskell-from-anything-1.0.1.0 failed during the configure step. The
exception was:
ExitFailure 1

这个 HSrts-ghc8.0.1 库是什么？我在哪里可以在Windows系统上找到它？或者我是否必须在Windows中手动安装此库？

与此同时，我尝试了＃34;堆栈＆＃34;工具并得到了类似的错误：

这在Windows（尚未）上无效。

call-haskell-from-anything似乎依赖于使用需要-dynamic支持的GHC版本。从他们的cabal文件：

ghc-options: 
   -- For building TemplateHaskell with cabal and -dynamic, we have to disable -dynamic sometimes 
   -no-hs-main -fPIC -shared -dynamic

同样-fPIC不是一个标志，因为Windows不使用/需要位置独立代码，因此在Windows上意味着什么。

HSrts-ghc8.0.1指的是由于https://ghc.haskell.org/trac/ghc/ticket/5987

而目前尚未在Windows上构建的GHC运行时的动态版本

我试图通过8.2.1完成此操作，这应该再次支持动态编译。但是现在，抱歉，这个包不起作用。

可能不需要动态支持，因此您可以尝试解压缩项目并编辑cabal文件，删除-fPIC和-dynamic。
