我正在尝试terminfo在我的 Windows Cygwin 安装上安装 cabal 包，但由于curses标题而失败：

$ cabal install terminfo

Failed to install terminfo-0.3.2.5
cabal.exe: Error: some packages failed to install:

同时，正确安装了 NCurses (/usr/include/ncursesw和ncurses)。如果在编译之前我明确将该子文件夹添加到 GCC，它将继续

export C_INCLUDE_PATH=/usr/include/ncursesw

重新运行 cabal 产生了另一个错误：

...

cabal.exe: Missing dependency on a foreign library:
* Missing (or bad) header file: ncurses.h
* Missing C library: ncursesw
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.

所以我尝试cabal install terminfo --extra-lib-dirs=/lib/ncursesw了，但后来我意识到 cabal 是一个 Windows 应用程序，所以我也尝试过--extra-lib-dirs=c:/cygwin/lib/ncursesw

最后，最终解决方案如下：

  1. 在那里安装 Cygwin 并ncursesw-devel打包
  2. 运行 cygwin 并配置 GCC： $ export C_INCLUDE_PATH=/usr/include/ncursesw
  3. 由于C:\cygwin\usr\include\ncursesw\ncurses.h是 Cygwin 中的软引用，因此您应该手动将此文件替换curses.h为同一文件夹中的文件

  4. 现在，您可以从同一个 Cygwin 终端启动 Cabal（它是一个 Windows 程序！）：

    $ cabal install terminfo --extra-lib-dirs=c:/cygwin/lib --extra-include-dirs=c:/cygwin/usr/include/ncursesw --extra-include-dirs=c:/cygwin/usr/include

因此，安装了库。但是当我尝试实际使用该功能时，ghc 抱怨：

Loading package terminfo-0.3.2.5 ... linking ... ghc.exe: c:/cygwin/lib\libncursesw.a: unknown symbol `__imp____ctype_ptr__'
