WxHaskell/Windows

wxWidgets 2.9 and wxHaskell 0.90.x

Windows	Haskell Platform	wxWidgets
7	2011.2.0.1	2.9.3

Prerequisites:

• 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)
• WXC_VERSION: 0.90.0.2
• 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%

Steps:

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
   

DLLs

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 2^nd 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.
