Question

我开始通过堆栈安装threadscope（而不是cabal，是吗？https://wiki.haskell.org/ThreadScope）。 threadscope需要cairo。

$ stack install cairo
cairo-0.13.3.1: configure

--  While building package cairo-0.13.3.1 using:

          In an equation for ‘main’:
              main = defaultMainWithHooks gtk2hsUserHooks

进一步追逐，我尝试安装gtk构建工具：

$ stack install gtk2hs-buildtools

Copied executables to /home/username/.local/bin:
- gtk2hsC2hs
- gtk2hsHookGenerator
- gtk2hsTypeGen

我在cairo安装时遇到了同样的错误。我正在运行Ubuntu 14.04并安装了libcairo2-dev：

$ stack install threadscope

堆栈版本：

$ stack --version
Version 1.3.2, Git revision 3f675146590da4f3edf768b89355f798229da2a5 (4395 commits) x86_64 hpack-0.15.0

Cabal版本：

$ stack exec cabal -- --version
cabal-install version 1.24.0.1
compiled using version 1.24.1.0 of the Cabal library

其他版本：

$ sudo apt-get install libgtk2.0-dev libpango1.0-dev libglib2.0-dev libcairo2-dev libghc-gtk-dev

我在这里提出这个而不是超级用户或ubuntu的原因是这个错误：

  • Couldn't match expected type ‘Distribution.Simple.UserHooks.UserHooks’
                  with actual type ‘Cabal-1.24.1.0:Distribution.Simple.UserHooks.UserHooks’

似乎暗示Haskell包代码本身有一些时髦的东西，希望它在一个模块中，在某种程度上更深层次，在cabal- *中，对吧？

尚未清除的其他参考资料：

Answer 1

我认为这与recently

的问题相同

你能试试吗

Using System.Linq; ... comboFms.Items.AddRange(fmsDB.Where(s => !string.IsNullOrEmpty(s)).ToArray());

并查看是否能解决问题。

==编辑：==

但是，为了回答您的第一个问题，我可以使用以下命令通过堆栈安装threadscope，

stack setup --upgrade-cabal

但我使用的是Arch Linux。

Answer 2

为了成功汇编cairo，您需要支持新的custom-setup feature in Cabal 1.24。官方发布的Stack版本尚未支持此功能，但master上提供了支持。为了安装它：

运行stack upgrade --git --source-only
确保目标目录（通常为$HOME/.local/bin）位于PATH
为了更加确定，请运行stack --version和which stack

在此之后，stack build cairo应该有效。
