cabal报告“/ usr / bin / ld：找不到-lHSrandom-1.0.1.1-ghc7.8.3” [英] cabal reports "/usr/bin/ld: cannot find -lHSrandom-1.0.1.1-ghc7.8.3"

问题描述

我有Ubuntu 14.04LTS。我从 http：// www下载了最新的 ghc-7.8.3 .haskell.org / ghc / download_ghc_7_8_3＃x86_64linux 并将其安装到 / usr / local 。

然后我将 cabal 更新为版本 1.20.0.3 。

我在终端输入 cabal安装QuickCheck ，得到：

顺便提一下，我已经有 haskell-platform with ghc-7.6.3 通过 apt-get 安装。 / p>

解决方案

我记得在设置ghc-7.8时有类似的问题。它与新cabal有关，它与旧版versio安装的库不兼容（但它没有给出正确的问题原因。）

无论如何，我想重新安装有问题的软件包

  cabal install random --reinstall --force-reinstalls 
  

设置为 cabal install tf-random 应该会成功。

I have Ubuntu 14.04LTS. I downloaded the latest ghc-7.8.3 from http://www.haskell.org/ghc/download_ghc_7_8_3#x86_64linux and installed it to /usr/local.

Then I updated my cabal to version 1.20.0.3.

I typed cabal install QuickCheck into my terminal, and got:

BTW, I already have haskell-platform with ghc-7.6.3 installed via apt-get before.

解决方案

I remember having a similar issue when setting up ghc-7.8. It has something to do with the new cabal, which somehow isn't compatible with libraries installed with an older versio (but it fails to give the correct problem reason.

Anyway, I think reinstalling the packages in question

cabal install random --reinstall --force-reinstalls 

sets it up so cabal install tf-random should then succeed.
