“所请求的模块与接口文件”中找到的名称不同“ [英] "requested module differs from name found in the interface file"

问题描述

我想要的是： cabal 来构建我的模块; make 来构建这个脚本。

脚本链接到Objective-C（参见 https://github.com/mchakravarty/language-c-inline/tree /主/测试/ objc /编组阵列）。当我构建脚本时，它在导入时失败：

$ $ $ $ $ $ $ Main.hs：1：1：
错误的接口文件：dist / build / Commands / OSX / Events.hi
有些问题;请求的模块main：Commands.OSX.Events不同于在接口文件命令中找到的名称-.0.0：Commands.OSX.Events

这里有一些文件内容：

  $ cat Makefile 
 PACKAGES = -package template- haskell -package language-c-quote -package language -c-inline -package命令
 FRAMEWORKS = -framework Carbon -framework Cocoa -framework Foundation 
 LDFLAGS = $（PACKAGES）$（FRAMEWORKS）
 Main：o 
 cabal exec  -  ghc -o Main Main.o $（LDFLAGS）
 Main.o：
 cabal build 
 cabal exec  -  ghc -c Main.hs -idist / build / -v 
 ... 
 
 $ cat commands.cabal 
 exposed-modules：Commands.OSX.Events 
 hs-source -dirs：sources 
 ... 
 
 $ ghc --show-iface dist / build / Commands / OSX / Events.hi 
 interface commands-0.0.0：Commands。 OSX.Events 7083 
 ... 
 
 $ cat sources / Commands / OSX / Events.hs 
 module Commands.OSX.Events where 
 ... 
 
 $ cat Main.hs 
 import Commands.OSX.Events 
 ... 
  

cabal构建成功，并且可执行文件编译并运行成功，如果我只是把所有内容放在同一目录下，并忽略cabal。

1. 我可以告诉GHC一些模块是一些软件包的一部分吗？
   

2. 我可以使用这些外部依赖软件创建一个cabal可执行文件吗？




3. 其他任何解决方案

4. 模块包工作：

     ghc -package-name commands-0.0.0 
     

   http://www.haskell.org/ghc/docs/7.2.1/html/users_guide/packages.html

   
   

   What I want is: cabal to build my modules; make to build this one script.

   The script links to Objective-C (see https://github.com/mchakravarty/language-c-inline/tree/master/tests/objc/marshal-array). when I build the script, it fails on the import:

   $ make
   Main.hs:1:1:
       Bad interface file: dist/build/Commands/OSX/Events.hi
           Something is amiss; requested module  main:Commands.OSX.Events differs from name found in the interface file commands-0.0.0:Commands.OSX.Events
   

   here are some file contents:

   $ cat Makefile
   PACKAGES   = -package template-haskell -package language-c-quote -package language-c-inline -package commands
   FRAMEWORKS = -framework Carbon -framework Cocoa -framework Foundation
   LDFLAGS    = $(PACKAGES) $(FRAMEWORKS) 
   Main: Main.o
       cabal exec -- ghc  -o Main Main.o $(LDFLAGS)
   Main.o:
       cabal build
       cabal exec -- ghc  -c Main.hs -idist/build/ -v
   ...
   
   $ cat commands.cabal
    exposed-modules: Commands.OSX.Events
    hs-source-dirs: sources
   ...
   
   $ ghc --show-iface dist/build/Commands/OSX/Events.hi
   interface commands-0.0.0:Commands.OSX.Events 7083
   ...
   
   $ cat sources/Commands/OSX/Events.hs
   module Commands.OSX.Events where
   ...
   
   $ cat Main.hs
   import Commands.OSX.Events
   ...
   

   the cabal build is successful, and executable compiles and runs successfully, if I just put everything in the same directory, and ignore cabal.

   1. can I tell GHC that some module is part of some package?

   2. can I make a cabal executable, with these external dependencies?

   3. any other solutions?

   解决方案

   explicitly naming the modules package worked:

   ghc -package-name commands-0.0.0
