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
