ncurses in Haskell for Windows
Comment
1 / 1
Using ncurses library in Haskell on Windows requires additional setup steps due to the underlying C library's platform dependencies. Here's a general outline of the steps involved:
Install the ncurses library on your Windows system:
- Download the PDCurses library, which is a Windows port of ncurses, from the PDCurses repository on GitHub: https://github.com/wmcbrine/PDCurses.
- Compile the PDCurses library according to the provided instructions.
- Once compiled, you should have the PDCurses library files (e.g.,
pdcurses.dll
,pdcurses.lib
).
Configure Haskell environment:
- Ensure you have Haskell Platform or GHC installed on your Windows system.
- Open a command prompt and navigate to your Haskell project directory.
Install the necessary Haskell packages:
- Run the following commands to install the required Haskell packages:bash
cabal update
cabal install ncurses
- Run the following commands to install the required Haskell packages:
Configure the build process:
- Create a
.cabal
file in your project directory if you don't already have one. - Add
ncurses
as a dependency in the.cabal
file:cabalbuild-depends: base >=4.14 && <4.15,
ncurses >=0.2 && <0.3
- Save the
.cabal
file.
- Create a
Build and run your Haskell program:
- Open a command prompt and navigate to your project directory.
- Run the following commands to build and run your Haskell program:bash
cabal build
cabal run
Remember to update the package versions in the .cabal
file based on the specific versions available in your Haskell environment.
Please note that the steps provided above are a general guideline, and there may be slight variations based on your specific project setup and the Haskell tooling you're using.
