Hi all, On behalf of the wxHaskell maintainers, I am very pleased to announce the release of wxHaskell 0.12.1.2. The key feature of this release is that it is now possible to install wxHaskell entirely using cabal on all targets (with a minor proviso on Windows). The credit for this achievement is almost all down to new contributor Brian Lewis, who has worked very hard to make this work 'just right', and given me (at least) an object lesson in how to use Cabal. The small proviso for Windows machines is that wxWidgets should be built using MSys - none of the other compilers supported by wxWidgets is currently working, but we consider this a small price to pay for the convenience of getting a GUI straight from cabal. For Unix machines which have wxWidgets 2.8.x installed, you should now be able to install wxHaskell with a simple: cabal install wx For Windows machines, there are a few prerequisites: 1) You will need the Windows port of wx-config in your path. This can be downloaded from http://wxconfig.googlepages.com/ 2) You will need to compile wxWidgets using MSys. We have tested against MinGW 5.1.6 with g++ compiler, MinGW Make, MSYS-1.0.11, wxMSW-2.8.10, which are the latest versions, and can be downloaded from their respective websites. I used a completely clean install of the latest Haskell Platform to validate the procedure. Please note: all commands to be entered in an MSys shell. cd /c/path/to/wxWidgets-2.8.10/build/msw mingw32-make -f makefile.gcc BUILD=release MONOLITHIC=1 SHARED=1 UNICODE=1 set PATH=$PATH:/c/path/to/wx-config set WXWIN=/c/path/to/wxWidgets-2.8.10 set WXCFG=gcc_dll/mswu cabal install wx I will be updating the wxHaskell wiki to reflect these changes over the next day or so. Best Regards Jeremy O'Donoghue on behalf of the wxHaskell maintainers.
