wxWidgets 2.9 and wxHaskell 0.90.x

Windows	Haskell Platform	wxWidgets
7	2011.2.0.1	2.9.3

Prerequisites:

• MinGW

Environment variables:

• CABAL_DIR: C:\Users\XXX\AppData\Roaming\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
4. Download wxHaskell source
5. Build wx-config

cd %WXHASKELL_DIR%\wx-config-win\wx-config-win
g++ wx-config.cpp -o wx-config.exe
cp wx-config.exe %CABAL_DIR%\bin
cabal install wxdirect
cabal install wxc
cabal install wxcore
cabal install wx

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.
