如何重新分发wxHaskell应用程序？

Question

我正在使用ghc 7.6.3.我从这里安装了wxHaskell:https://github.com/wxHaskell/wxHaskell

它工作,示例程序编译和运行成功.

现在唯一的问题是我想在mac OS X上分发一个wxHaskell应用程序.我尝试使用macosx-app和cabal-macosx(https://github.com/michaelt/cabal-macosx)制作一个"app"文件.它在我的机器上运行正常,但无法在另一台计算机上运行.我收到以下错误:

Dyld Error Message: Library not loaded: /Users/user/.cabal/lib/wxc-0.90.1.0/ghc-7.6.3/libwxc.dylib.

我使用的是OS X 10.8.4(Mountain Lion),但我也有兴趣在Windows上编译应用程序并重新分发它们.

什么是重新分发wxHaskell应用程序的最佳方法？

Setup.hs

-- Example Setup.hs for the wxHello app.

import Distribution.MacOSX
import Distribution.Simple

main :: IO ()
main = defaultMainWithHooks $ simpleUserHooks {
         postBuild = appBundleBuildHook guiApps -- no-op if not MacOS X
       }

guiApps :: [MacApp]
guiApps = [MacApp "WxHello"
                  (Just "resources/WxHello.icns")
                  Nothing -- Build a default Info.plist for the icon.
                  [] -- No other resources.
                  [] -- No other binaries.
                  ChaseWithDefaults -- Try changing to ChaseWithDefaults
          ]

Answer 1

包含您的 .cabal 和 Setup.hs 文件可能会有所帮助。

从 cabal-macosx 的文档来看，您似乎需要确保 Setup.hs 中的 MacApp 数据值获得适合ChaseDeps的模式（使用ChaseWithDefaults而不是DoNotChase），以便构建可再发行的应用程序包。

如果您已经这样做了，但仍然遇到相同的错误，我会检查生成的应用程序包，看看是否复制了必要的库。您可能会找到足够的信息来向 cabal-macosx 维护者提交错误。

编辑

根据您所包含的内容，设置看起来是正确的，并且似乎至少复制了库依赖项。我认为问题可能出在 cabal-macosx 包上。

查看依赖项修复代码的源代码，看起来它应该"Updating <library>'s dependence on <path> to <path>"在构建捆绑包时打印一堆行。你看到那些了吗？是否有任何行更新二进制文件本身？

我对 OS X 链接过程不是很有经验，但我认为除非在复制库后链接二进制文件，否则它也需要更新。您应该能够使用/usr/bin/otool -L <filename>并/usr/bin/install_name_tool手动修复安装过程中可能丢失的二进制文件中的路径。
