如何升级gtk2hsC2hs？ [英] How to upgrade gtk2hsC2hs?

问题描述

我正在使用cabal-install 0.10.2在我的Ubuntu 11.10下试用 cabal install glib-0.12.3 。但是，它显示以下错误消息：

  setup：程序gtk2hsC2hs版本> = 0.13.5是必需的，但版本在/ usr / bin / gtk2hsC2hs中找到的
版本是0.13.4 
 cabal：错误：某些包未能安装：
 glib-0.12.3在配置步骤中失败。例外情况是：
 ExitFailure 1 
  

经过半个小时的搜索，我找不到这里 gtk2hsC2hs 是。我挖入像 http://code.haskell.org/gtk2hs/tools/c2hs/ ，但似乎无法找到正确的版本。

我如何升级我的gtk2hsC2hs？谢谢！

gtk2hs-buildtools 包。

  $ cabal install gtk2hs-buildtools 
  
 
 
（也许使用  -  global 标志，取决于您想要如何安装一般的软件包）应该为您提供最新的版本，它应该能够构建最新的 gtk2hs 软件包。
 
 
 
由于旧的 gtk2hsC2hs 位于 / usr / bin 中，所以请确保新的安装在那里（替换旧的）或在 $ PATH 中出现在 / usr / bin 之前的目录中。默认 cabal install 在 $ HOME / .cabal / bin 中安装可执行文件（在Linux上），所以它会是好主意让 $ PATH 中的第一个目录。
 
I am trying cabal install glib-0.12.3 under my Ubuntu 11.10 using cabal-install 0.10.2. However, it shows the following error messages:
setup: The program gtk2hsC2hs version >=0.13.5 is required but the version
found at /usr/bin/gtk2hsC2hs is version 0.13.4
cabal: Error: some packages failed to install:
glib-0.12.3 failed during the configure step. The exception was:
ExitFailure 1
After half an hour's search, I cannot find where this gtk2hsC2hs is. I dug into places like http://code.haskell.org/gtk2hs/tools/c2hs/, but could not seem to find the right version.

How could I upgrade my gtk2hsC2hs? Thanks!
解决方案
It's part of the gtk2hs-buildtools package.
$ cabal install gtk2hs-buildtools
(maybe with the --global flag, depends on how you want to install packages in general) should provide you with the newest version that should be able to build the latest gtk2hs packages.

Since the old gtk2hsC2hs is in /usr/bin, make sure that the new one is either installed there (replacing the old) or in a directory appearing before /usr/bin in your $PATH. A default cabal install installs executables (on Linux) in $HOME/.cabal/bin, so it would be a good idea to have that the first directory in the $PATH.
