I'm in the process of trying to pull this all together.

One piece of good news is that I have just gotten my hands on a MacBook Pro
with a copy of VMWare Fusion. This means I have all of our supported
platforms available to me to test (well, a 32 bit Debian Stable, 64 bit
Windows 7 Enterprise and OSX Lion, which is a pretty good cross-section, I
think).

The less good news is that every attempt I have made to merge Dave's branch
with the mainline automatically has failed. I have given up and am doing
the merge manually.

This will result in identical source code in the end (I'm taking some care
over that), but there's a fair chance that I'll miss off some of the
check-in comments, although I'm doing my best to follow the order in which
work was done on the code.

Manual merging is not huge fun, and pretty painstaking, so please bear with
me - I want to get it right before I commit anything for wider use.

I had forgotten to actually push the modified versions of the patches for 
wxcore/Setup.hs
(and another patch)

Basically it was vainly trying to link against libwxmsw29ud_xrc (windows 
wxWidgets libs) instead of the equivalent Mac versions

Not sure if that alone resolves Doaitse's issue though.

Sorry for the resulting noise and confusion!

This could be the problem that the "install-name" of a shared library
on the mac needs to be set to the correct absolute path to be able to
link.
I encountered the same problem with the shared library version of
wxHaskell from Dave's branch (allowing ghci to work with wx!). That
version is working on my mac with wx2.9.3 for Xcode 4.2. I explained
the required fixes here :

We have spent a couple of hours now, patching, editing, trying to update etc.

1) We updated Alessandro's brew file to install wxmac2.9.3
2) All cabal files for wx say they only work for 2.8
3) We have added the changes needed for 7.4 (array, Eq, Show etc)
4) When trying to configure wxcore we get:

cabal configure --extra-lib-dirs=/usr/local/lib


generated 1461 methods for 114 classes.
generating: src/haskell/Graphics/UI/WXCore/WxcClassesMZ.hs
generated 2326 methods for 123 classes.
generating: src/haskell/Graphics/UI/WXCore/WxcClasses.hs
generated 3787 total methods for 237 total classes.
ok.
Configuring wxcore-0.13.1.1...
setup: Missing dependencies on foreign libraries:
* Missing C libraries: wx_baseu-2.9, wx_baseu_net-2.9, wx_baseu_xml-2.9,
wx_osx_cocoau_core-2.9, wx_osx_cocoau_adv-2.9, wx_osx_cocoau_qa-2.9,
wx_osx_cocoau_html-2.9, wx_osx_cocoau_webview-2.9, wx_osx_cocoau_xrc-2.9
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
dyn-81-83:wxcore doaitse$ 

The directory /usr/local/lib contains versions of these files with their names 
prefixed by "lib".

5) We tried to edit Setup.hs in order to prefix the files with this "lib", 
leading to a similar error message;

Hmm, what does

I think it's perfectly normal that the filenames are prefixed by 'lib'

Is there any chance that you have an old wx-config lying around that's more 
easily reached than the 2.9 Cocoa one?

2012-03-07 Thread Eric Kow 
Hi all,

Just a couple of minor follow-ups on the issue of getting wxHaskell to work on 
MacOS X Lion

1. I noticed this piece of text from the wxWidgets wiki [wxWidgets]:

If you want 64-bit wxWidgets on OS X you'll need 2.9+ and configure 
-with-osx_cocoa - see below; but remember that 2.9 is not an official, stable 
release and wxOSX/Cocoa is not yet complete.

This means that Lion users (and Snow Leopard with 64 bit GHC) will *have* to 
use the Cocoa build after all, no choice about it.  I'd been using it pretty 
much for the heck of it, but it turns out to have been a fortunate choice.

2. Doaitse, I'm sorry, it seems your cry for help last October happened before 
people started trying to use wxHaskell on Lion.  Did you see this recent thread 
with hopefully more of a guide?

3. Otherwise, have not yet had a chance to poke around and see if there is a 
way to make things work with just one of Jeremy's or Dave's branches.  So will 
be using the patch bundle I mentioned in this email thread until then.

Thank you very much, with this process it appears to work, although
there are some slight issues with usage. I'll be testing it out a bit
before writing an updated guide on the wiki.

Sarah,

The good news is that it *can* be done.  I know because I'm on Lion, and I'm 
using wxHaskell.

The bad news is that it may still involve manually applying some patches (I'm 
not up to speed about the latest state of wxHaskell) and also installing 
wxWidgets by hand.

Your two challenges are to install the right wxWidgets version with the right 
set of flags (you want Unicode, for starters), and then to get a version of 
wxhaskell that works with it.  I'm using wxWidgets 2.9, for what it's worth

using the --framework option).

You will also need 32-bit support for Python. If you are on a 64-bit
platform, you will need to run Python in 32-bit mode:

  arch -i386 python [args]

Homebrew Python does not support this by default (compile using the
--universal option)

  EOS
end

return s
  end
end


For the wxHaskell patches, unless somebody from the team obsoletes my message, 
you should be able to grab them at this old thread http://ur1.ca/8erik and 
apply them using something like

darcs get --lazy http://code.haskell.org/wxhaskell 
the-patch-you-downloaded.dpatch
cd wxhaskell
darcs apply -i ~/foo/the-patch-you-downloaded.dpatch

See also the NOTES file in the thread.

[wxhaskell-users] Working guide for wxWidgets and wxHaskell on Mac OS X Lion 64 bit

2012-02-27 Thread Sarah Brofeldt 
Hello everyone,

I've been trying frantically to get a working setup of wxHaskell and
wxWidgets on my Mac recently, but to no avail. I was wondering if
anyone knows how exactly to go about it. I've tried just about every
combination of old and new versions of wxWidgets from homebrew as well
as older wxcore releases. How do you do it?
