安装Cabal-1.20.0.2失败

Question

当我试图安装Cabal-1.20.0.2时，会出现这个错误：

$ cabal install Cabal-1.20.0.2.tar.gz 
Resolving dependencies...
Configuring Cabal-1.20.0.2...
Failed to install Cabal-1.20.0.2
Last 10 lines of the build log ( /home/yonutix/.cabal/logs/Cabal-1.20.0.2.log ):
cabal: Error: some packages failed to install:
Cabal-1.20.0.2 failed during the configure step. The exception was:
user error (
/tmp/Cabal-1.20.0.2-11804/Cabal-1.20.0.2/Distribution/Simple/Utils.hs:386:31:
Warning:
In the use of ‘runGenProcess_’
(imported from System.Process.Internals):
Deprecated: "Please do not use this anymore, use the ordinary
'System.Process.createProcess'. If you need the SIGINT handling, use
delegate_ctlc = True (runGenProcess_ is now just an imperfectly emulated stub
that probably duplicates or overrides your own signal handling)."
/usr/bin/ld: cannot find -lgmp
collect2: error: ld returned 1 exit status
)

我需要安装这个软件包，因为阴谋集团安装取决于它。

有什么问题吗？谢谢!

日志文件的这一部分指出了这个问题：

/usr/bin/ld: cannot find -lgmp

ghc找不到libgmp。最有可能的修复方法是安装libgmp-dev包，例如在Ubuntu下面：

sudo apt-get install libgmp-dev
