1 Overview

This page describes how to get a working wxHaskell installation on various platforms. The latest release (version 0.10.3) was on 2008-03-23.

The installation process has become increasingly stable and simple, but some of the information on this page could become outdated. Current development on wxHaskell takes place in the darcs repository at http://darcs.haskell.org/wxhaskell .

2 Getting wxWidgets

wxHaskell 0.10.x does not yet support wxWidgets 2.8 (although the current darcs version does). Generally, the recommended version to use is 2.6.4 [2.6.3 on Debian/Ubuntu Linux] as it's what the binaries are compiled against.

  • Windows:
    • Binary - you can skip this phase. you should just install wxHaskell. Because wxHaskell's dll statically links wxWidgets library.
  • MacOS X
    • Tiger - do not use the wxMac 2.5 that comes pre-installed, unless you really want to compile from source and to report back on how everything works out.
    • Leopard - the darcs version of wxhaskell now (2008-04-25) supports wxWidgets 2.8. We don't know if the one that ships with Leopard works yet. Want to give it a try? Otherwise, we do know that it runs with a self compiled wxMac.
  • Linux - the wxWidgets that ships with your system (as long as it's the 2.6 one and not the 2.8 one) should work.

See the wxWidgets site for more details.

In addition, the following pages contain useful information on installing wxWidgets 2.6.4 (or, in some cases, wxWidgets 2.6.3) on various operating systems:

3 Getting wxHaskell

Obtain wxHaskell sources from Sourceforge.

OSX caveats:

  • The installation of wxWidgets provided with OSX Tiger will not work, as it does not have the wxThread symbols that wxHaskell does want to link against.
  • Programs compiled with wxHaskell do not work by default: you need to run macosx-app on them to let Mac OS X understand that the binary needs Carbon to do its UI.

4 Building and installing

4.1 Windows

4.1.1 GHC 6.8.3, wxWidgets 2.6.4, wxHaskell 0.10.3 (binary)

  1. Download the wxhaskell binary from sourceforge
  2. Unpack wxhaskell-*.zip. And double-click wxhaskell-*\bin\wxhaskell-register.bat.
  3. wxhaskell-register.bat install wxHaskell to your system.

4.1.2 Assumptions (a.k.a. what I have tested)

  • GHC 6.4.2 (Jason Dagit reports success with GHC 6.5 as well).
  • Cygwin installation. See | wxHaskell cygwin page for detail, but broadly, you need Cygwin bash and install binaries.
  • wxWidgets built/installed in a path with no spaces in it. Actually you can use a path with spaces but there are a few rules. For example, I had ghc installed to this location:
    C:\Program Files\Visual Haskell
    So this required me to use the following configure command:
    ./configure --libdir=C:/Progra~1/Visual~1

The two important things here are: 1) You must use the forward slash and 2) you cannot use spaces.

Next I found that I needed to add C:\Program Files\Visual Haskell to my path so that the wxHaskell dlls could be located by windows.

  • Environment variables:
    • PATH should include MinGW and Cygwin binary directories. MinGW must come before Cygwin in PATH.
    • WXHASKELL environment var points to wxHaskell install directory.
    • WXWIN environment directory points to wxWidgets install directory.

For more detailed information, see Installing wxWidgets 2.6.4 on Microsoft Windows 9x/ME, Windows NT, Windows 2000, Windows XP, and Windows CE.

4.2 Mac OSX

4.2.1 Mac (Intel and PowerPC), Tiger (10.4.11), GHC 6.8.2, wxWidgets 2.6.4, wxHaskell 0.10.3 (binary)

  1. Download and install wxWidgets for mac (wxMac 2.6.4) from http://www.wxwidgets.org/ (make sure you configure with --enable-unicode)
  2. Download the wxhaskell binary from sourceforge
  3. Open the dmg, double-click the .pkg file

For more detailed information, see Installing wxWidgets 2.6.4 on Mac OS X or Installing wxWidgets on wxCocoa.

4.2.2 MacIntel, Tiger (10.4.11, XCode 2.5), GHC 6.8.2, wxWidgets 2.6.4, wxHaskell 0.10.2 (hackage)

built on 2008-02-16

  1. Download and install wxWidgets for mac (wxMac 2.6.4) from http://www.wxwidgets.org/
    • I changed into the wxMac topdirectory and used: ./configure --disable-monolithic --enable-display --enable-unicode --with-opengl --with-mac --without-odbc --enable-mediactrl && make && sudo make install
    • sudo mkdir -p /usr/local/wxhaskell/bin
    • sudo ln -s /usr/local/bin/wx-config /usr/local/wxhaskell/bin
  2. sudo cabal install wx-core
  3. cabal install wx
  • Enjoy. The TimeFlows and BoucingBalls examples still suffer from not having a correct default background color. This should not affect you too much: just explicitly set the background color.
    • Note that you need to run macosx-app on the programs you have built before you can manipulate the windows that program puts up. This installation process puts it in /usr/local/wxhaskell/bin/macosx-app
  • Does wxWidgets 2.8.0 work at all? [yes! in the darcs version of wxhaskell as of 2008-04-25]

Again, for more detailed information, see Installing wxWidgets 2.6.4 on Mac OS X or Installing wxWidgets on wxCocoa.
