Haskell 尼克松+；哈斯克尔&x2B；opengl（先决条件）

不幸的是，我没有从OpenGL教程中得到一个简单的示例程序

ghc --make gfx.hs
Could not find module ‘Graphics.UI.GLUT’
[..]

然后我尝试了以下方法：

cabal install GLUT

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.

看起来问题出在缺少C库上。我正在使用nixOS，有人知道我必须执行哪些步骤才能运行它吗？

在Linux上（Nix是Linux发行版），LSB指定

libGL

是桌面配置文件的一部分。这意味着至少要安装X11客户端库<代码>libGL有点特殊，允许图形驱动程序安装覆盖它

这归结起来就是：为你的GPU安装图形驱动程序。如果您使用的是Intel或AMD GPU，请安装Mesa驱动程序。如果您的系统有NVidia GPU，我建议使用专有的NVidia驱动程序。

在nixos中，库通常不在cabal期望的路径上可用。请尝试以下操作：

cabal install GLUT

nix shell-p libGL libGLU freeglut
阴谋集团

如果要使用nix shell：

$ nix-shell -p 'haskellPackages.ghcWithPackages (p: [ p.GLUT ])'

将给您一个带有

ghc

的shell，它知道

GLUT

我已尝试使用此代码（来自您提到的wiki）

对于更大的项目，您可能希望使用

cabal

或

stack

，但我认为这将是另一种情况。

请参阅我关于类似问题的说明。nixos不使用LSB文件系统层次结构。这就是问题的关键所在。@Turion：我指的不是LSB文件系统层次结构，而是LSB集合的要求，如果是桌面环境，则必须按名称指定哪些库——请注意，只指定了库的基本名称，而不是它在文件系统树中的位置。顺便说一句：我和一些NixOS开发人员是亲密的朋友，喜欢与他们进行技术讨论（也包括关于Nix的讨论）。
