无法安装网络包
问题描述：
我已经安装了网络包。当我尝试重新安装它时（例如，用于cabal-dev），它将不会编译。如果我cabal unpack network，然后尝试构建，我得到下面的输出。我猜测这是因为我升级了一个Ubuntu依赖项。我升级到了Ubuntu 11.04，希望它有所帮助;它没有。还安装了libghc6-network-dev以防万一链接正确;它没有。我在ghc-7.0.2上，也试过ghc-7.0.3。目前尝试从源代码安装最新的哈斯克尔平台...任何帮助表示赞赏 - 这是完全杀死我的哈斯克尔黑客！无法安装网络包

命令是：

这里是我的gcc版本：
/usr/bin/gcc --version gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2
答
我升级到7.0.3 GHC，然后安装了7.0 .3源码来自haskell平台，现在一切正常。不是我明白了为什么:)
答
如果我没有记错的话，旧版本的cabal-install有问题。尝试安装最新版本
cabal install cabal-install-0.10.2
适用于Ubuntu 10.10的gcc 4.4.5。 – 2011-05-23 05:04:33
