wxWidgets 2.9 and wxHaskell 0.90.x

Windows Haskell Platform wxWidgets
7 2011.2.0.1 2.9.3


  • MinGW 5.1.6 and MSYS 1.0.11 (these are the latest versions at the time of writing). You must select the C++ compiler option when installing MinGW.

Environment variables:

  • CABAL_DIR: C:\Users\XXX\AppData\Roaming\cabal (Windows XP: C:\Documents and Settings\XXX\Application Data\cabal, or for all Windows versions: %APPDATA%\cabal)
  • GHC_VERSION: 7.0.3 (for our convenience)
  • WXWIN: C:\wxWidgets-2.9.3
  • WXCFG: gcc_dll\mswu
  • PATH: (add these) %WXWIN%\lib\gcc_dll;%WXWIN%;%CABAL_DIR%\wxc-%WXC_VERSION%\%GHC_VERSION%


  1. Download wxWidgets 2.9.3 source
  2. Extract to C:\wxWidgets-2.9.3
  3. Build wxWidgets-2.9.3
    I (who?) compiled it as follows: edit wxwidgets-src-dir\build\msw\config.gcc so that the following values are set:
     SHARED ?= 1
     BUILD ?= release

    Then (in cmd.exe, not bash):

     cd wxwidgets-src-dir\build\msw
     mingw32-make -f makefile.gcc
  4. Download wx-config.exe (a new version for wxWidgets > 2.9) and copy it somewhere into your path, for instance via
    cp wx-config.exe %CABAL_DIR%\bin
  5. Install the wxHaskell libraries
    cabal install wxdirect
    cabal install wxc
    cabal install wxcore
    cabal install wx


In order to run a wxHaskell application, the following wxWidgets DLLs must be in the search path:

(If you built wxWidgets in directory wxWidgets-2.9.3, the following files can be found in wxWidgets-2.9.3\lib\gcc_dll\ (change revision as needed))

  • wxbase293u_gcc_custom.dll
  • wxbase293u_net_gcc_custom.dll
  • wxbase293u_xml_gcc_custom.dll
  • wxmsw293u_adv_gcc_custom.dll
  • wxmsw293u_aui_gcc_custom.dll
  • wxmsw293u_core_gcc_custom.dll
  • wxmsw293u_gl_gcc_custom.dll
  • wxmsw293u_html_gcc_custom.dll
  • wxmsw293u_propgrid_gcc_custom.dll
  • wxmsw293u_ribbon_gcc_custom.dll
  • wxmsw293u_richtext_gcc_custom.dll
  • wxmsw293u_stc_gcc_custom.dll
  • wxmsw293u_xrc_gcc_custom.dll

The following file can be found in directory wxc\dist\build\, after building package wxc in directory wxc:

  • wxc.dll

Furthermore, the following DLLs need to be in the search path (these can be found in directory "Haskell Platform\2012.2.0.0\mingw\bin\", or in ghc-7.4.2\mingw\bin\ if you installed the compiler only (change revision as needed)):

  • libgcc_s_dw2-1.dll
  • libstdc++-6.dll
  • mingwm10.dll

Some wxHaskell applications also require the following DLLs:

  • uuid.dll
  • perl510.dll
  • libaprutil-1.dll

These DLLs can be obtained by installing XAMPP; the DLLs are in the directories:

  • XAMMP\xampp\perl\site\lib\auto\APR\UUID
  • XAMMP\xampp\perl\bin
  • XAMMP\xampp\apache\bin

wxWidgets 2.8 and wxHaskell 0.13.x

Follow SkyTreeBird's guide. It which walks you through the basic steps

  • wx-config
  • wxPack
  • setting up environment variables
  • cabal install wx

Note that the best way to refer to WxWidgets in your PATH is probably to use the WXWIN variable that you set, eg. %WXWIN%/lib/gcc_dll

The guide has been tested with the following configurations. Others may work too:

Windows Haskell Platform wxWidgets
XP 2010.2.0.0 2.8.10
7 2011.2.0.1 2.8.12

Troubleshooting installation with cabal

These remarks refer to wx-0.13.2 and Haskell Platform 2011.4.0.0 on Windows 7.

Cabal package wx depends on wxcore which depends on wxdirect. By default cabal installs on a per user base, thus wxdirect.exe will be installed to c:\Users\<YOUR NAME>\AppData\Roaming\cabal\bin\. This folder must be in your PATH for cabal install wxcore to succeed.

Package wxcore-0.13.2 does not work well with wx-config revision 21 2006-10-19 (downloaded from here on Feb 2nd 2012). If cabal install wxcore fails with an output containing "Usage: wx-config [options]" try this:

  • cabal unpack wxcore
  • cd wxcore-0.13.2
  • edit Setup.hs and comment out/remove the line containing "wx-config" ["--version"]
  • runhaskell.exe Setup.hs configure --user
  • runhaskell.exe Setup.hs build
  • runhaskell.exe Setup.hs install

Finally call cabal install wx.
