【问题描述】:
我建立了一个简单的 cabal 项目来尝试更好地熟悉它,并且我有一个非常简单的 Main.hs 文件:
main :: IO ()
main = putStrLn "Hello, World!"
然后我尝试构建它,使用cabal new-configure,然后使用cabal new-build。配置命令没有问题,但是构建它会给出:
[1 of 1] Compiling Main ( Main.hs, /home/redacted/Documents/Haskell/nixtut/dist-newstyle/build/x86_64-linux/ghc-8.0.1/newp-0.1.0.0/x/newp/build/newp/newp-tmp/Main.o )

这是我的 .cabal 文件:

我似乎无法理解出了什么问题。 GCC 已安装,我没有尝试链接任何外部库,我没有使用任何其他模块,我不知道这些引用暗示了什么。
感谢任何帮助,因为坦率地说,我不知道从哪里开始。我已经尝试在网上查找,但所有情况都不同,解决方案似乎不适用于我。我注意到对于其他人来说,当在 cabal 文件中存在链接或不包含模块的问题时,会发生类似的错误,但我不确定这如何或是否适用于此。
【问题讨论】:
-
您是否尝试查看
cabal new-build -v是否提供了更多信息? -
这看起来像是您的 Nix 构建环境的安装问题;
ghc --make Main.hs有效吗? -
@hvr ghc 可以编译,但你可能是对的,这是 nix 安装的问题。重新安装 nix 后,项目可以构建
