如何安装`帽子`

Question

我正在尝试获取Hat调试器。当我尝试：

cabal install hat或cabal install hat -v

最后我得到：

configure: error: in `/tmp/terminfo-0.4.0.0-17745/terminfo-0.4.0.0':
configure: error: curses headers could not be found, so this package cannot be built
See `config.log' for more details
Failed to install terminfo-0.4.0.0
cabal: Error: some packages failed to install:
haskeline-0.7.1.3 depends on terminfo-0.4.0.0 which failed to install.
hat-2.8.0.0 depends on terminfo-0.4.0.0 which failed to install.
terminfo-0.4.0.0 failed during the configure step. The exception was:
ExitFailure 1

我尝试解决问题：

cabal install terminfo

得到：

configure: error: in `/tmp/terminfo-0.4.0.0-18341/terminfo-0.4.0.0':
configure: error: curses headers could not be found, so this package cannot be built
See `config.log' for more details
Failed to install terminfo-0.4.0.0
cabal: Error: some packages failed to install:
terminfo-0.4.0.0 failed during the configure step. The exception was:

如何安装Hat？

Answer 1

假设您使用某种类型的Linux，应该有一个类似“libncurses5-dev”的系统包（这是Ubuntu中的名称），您可以安装它来获取curses头。

Answer 2

一旦在系统上安装了curses，

cabal install terminfo --extra-include-dirs=/path/to/curses/include --extra-lib-dirs=/path/to/curses/lib

当然适当替换/path/to/curses。

您平台的软件包管理器也可以直接安装terminfo，或者您可以使用单独的软件包管理器，即Nix package manager（特别受Haskellers欢迎）。
