Dear wxHaskell users / aspiring users, These are a few notes from getting a working 64bit installation of wxHaskell on Mac OS in case they are of any use to anyone. - This is for a 64-bit configuration starting from having 64-bit ghc 7.0.4 (HP 2011.4.0.0 64) - Mac os 10.6.8 snow leopard (with xcode 3.2.6) (This is not currently listed as a "known working configuration" at http://www.haskell.org/haskellwiki/WxHaskell/MacOS_X ) wxHaskell version issue: There is a linking problem with using the current wxc-0.90.0.3 and wxcore-0.90.0.1 from Hackage. They install ok but ghci throws a load of 'undefined symbols' when compiling from haskell using wxcore or wx . Thanks to Jeremy O'D. for identifying that the problem should disappear again in the latest development versions, which I got from: https://github.com/jodonoghue/wxHaskell So the following installation was completed: 1. wxWidgets 2.9.3 -----> installed globally (as dylib) in /usr/local... 2. cabal-macosx-0.2.2 (cabal install from Hackage) 3. wxdirect-0.90.0.1 (cabal install from Hackage) 4. wxc-0.90.0.4 <===<<< Development version from Github 5. wxcore-0.90.0.3 <===<<< Development version from Github 6. wx-0.90.0.1 (cabal install from Hackage) (plus some additional dependency packages pulled in by cabal not shown) wxWidgets ======== Stayed with wxWidgets 2.9.3 as being the current advertised 'stable' development release. 2.9 needed with wxHaskell 0.90 for 64bit. homebrew/macports may offer a convenient alternative approach to getting wxWidgets. I'm not familiar with these and don't have either installed so I just built wxWidgets myself as follows: Downloaded direct from http://wxWidgets.org/downloads/#latest_dev page (tar.bz2) to a local user directory. Configure to avoid any potential problems that may arise from https://github.com/jodonoghue/wxHaskell/issues/2 by temporarily editing out all inclusions of the QuickTime framework in the "configure" script file in the top level wxWidgets directory (only two places, simplest just to remove in both cases). - A response to a wxWidgets forum post suggested that the mac-related stuff is developing all the time and advocated pulling the latest widgets development build, but I stuck to 2.9.3 in the interests of stability. - Another small potential advantage to taking the latest widgets development build may be getting changeset 71086 which aims to stop the inclusion of the QuickTime framework for i86_64-ONLY widgets builds. Mac Snow-Leopard evidently (usually) comes with wxWidgets 2.8 pre-installed. I didn't want to alter the default Mac pre-installed stuff as far as possible, so adopted a configuration which left the 2.8 libraries installed and only disabled the 2.8 "wxrc" and "wx-config" executables in the path. If you want to check in advance for unlikely clashes with pre-existing stuff, then check /usr/local/lib where the dylib files "libwx_osx_cocoau_*" and a "wx" directory will be placed. /usr/local/bin will get new "wx-config" and "wxrc*" Assuming my setup is standard, wx-config for 2.8 should be found in the path at /usr/bin/wx-config and is a symlink to the main 2.8 stuff which is in /usr/lib so simply remove this link: $ sudo rm -iv /usr/bin/wx-config There is also wxrc which is a link to wxrc-2.8 in the same directory, so remove the link but leave wxrc-2.8 there: $ sudo rm -iv /usr/bin/wxrc (These links can then simply re-created to re-instate path access to the 2.8 executables if wanted again in the future.) Create and cd to suitably named wxWidgets build subdirectory, then: $ ../configure --enable-macosx_arch=x86_64 --enable-unicode --disable-debug --with-osx_cocoa --enable-stc --enable-aui --enable-propgrid --enable-xrc --enable-ribbon --enable-richtext --enable-webkit --with-opengl + $ make + $ sudo make install (/usr/local is the default prefix in "configure") Check with command: $ wx-config --list Default config is osx_cocoa-unicode-2.9 ... $ wx-config --version 2.9.3 Further checks: 1. cd to the wxWidgets samples and demos folders and "$ make" in each to check the samples and demos are working plausibly (I found a couple of odd things but generally were working). 2. Build "minimal.cpp" from https://github.com/kowey/debug-wx wxHaskell ======== Dependency chain wx -> wxcore -> wxc -> wxdirect Note: this is for a local user install. get master commit Merge branch 'GHCI_FIX_BRANCH' (at time of writing) eg. via CloneInMac at https://github.com/jodonoghue/wxHaskell wxdirect & cabal-macosx ----------------------------- $ cabal install wxdirect cabal-macosx wxc ----- cd to "wxc" folder of local copy from github The following configure parameters are based on http://www.haskell.org/haskellwiki/Mac_OS_X_Common_Installation_Paths but with an amendment to docdir to bring it in line with my local cabal config. $ runhaskell Setup configure --user --prefix=/Users/<YOURSELF>/Library/Haskell/ghc-7.0.4/lib/wxc-0.90.0.4 --libsubdir= --datasubdir= --docdir=/Users/<YOURSELF>/Library/Haskell/ghc-7.0.4/lib/wxc-0.90.0.4/doc + $ runhaskell configure build + $ runhaskell configure install wxcore -------- $ runhaskell Setup configure --user --prefix=/Users/<YOURSELF>/Library/Haskell/ghc-7.0.4/lib/wxcore-0.90.0.3 --libsubdir= --datasubdir= --docdir=/Users/<YOURSELF>/Library/Haskell/ghc-7.0.4/lib/wxcore-0.90.0.3/doc + $ runhaskell configure build + $ runhaskell configure install checks -------- Build wxcore "HelloWorld.hs" from https://github.com/kowey/debug-wx Wrap it with the macosx-app command. Enjoy. Note: It may start with the window positioned out of sight below left hand corner of the screen, don't miss it! wx --- This should have been a simple "cabal install wx" but for some strange reason I got: src/Graphics/UI/WX/Draw.hs:33:8: Could not find module `Graphics.UI.WXCore': Perhaps you haven't installed the profiling libraries for package `wxcore-0.90.0.3'? Use -v to see a list of the files searched for. cabal: Error: some packages failed to install: wx-0.90.0.1 failed during the building phase. The exception was: ExitFailure 1 $ cabal install wx --disable-library-profiling ...seems to solve it. checks -------- Build wx "HelloWorld.hs" from https://github.com/kowey/debug-wx Final Caveat ========= I have so far only compiled and run simple 'helloworld' type programs using wxcore and wx, so not more widely tested yet. YMMV/ Henry |
