Вот сообщение, которое я получаю при попытке установить через cabal-install:

cabal.exe: Missing dependencies on foreign libraries:
* Missing header file: HsReadline.h
* Missing C libraries: readline, ncurses
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
cabal.exe: Error: some packages failed to install:
readline-1.0.1.0 failed during the configure step. The exception was:
ExitFailure 1
У меня есть readline.h и еще много чего, и, кажется, он их находит. Отсутствие HsReadline.h как проблемы кажется странным: разве это не та часть пакета, которую я пытаюсь установить?
Буду признателен за любые советы о том, как заставить это работать. Я потратил несколько дней, пытаясь заставить это работать, будь то gnuWin32 readline, MinGW или cygwin.
