[wxhaskell-users] Installation on Mac OS X

[Wouter S. <ws...@Cs...>]

Dear all,

I've been trying to install wxhaskell on my iBook, so far to no  
avail. I'm running 10.4 with Wolfgang Thaller's ghc version 6.4.1 and  
XCode 2.1. So far I have managed to build managed to build and  
install wxMac 2.6.2 (which oddly enough seems to correspond to  
wxwidgets 2.5.3).

Wxhaskell configures as follows:

configuration:
library:     wxhaskell-0.9.4  (release 0)
compiler:    ghc-6.4.1
wxwidgets:   mac-2.5.3
with openGL: no
library dir: /usr/local/wxhaskell/lib

But building gives me the error attached at the bottom of this message.

I tried the binaries provided, but alas:

 > ghc -package wx HelloWorld.hs -o hello

HelloWorld.hs:4:0:
     Failed to load interface for `Graphics.UI.WX':
         Bad interface file: /usr/local/wxhaskell/lib/imports/ 
Graphics/UI/WX.hi
             mismatched interface file versions: expected 6041, found  
6040


Any clues as to what's amiss would be greatly appreciated.

Thanks in advance,

--Wouter

Hi,

1. For wxhaskell's configure, you need to pass the flag=20
   --wx-config=3D/usr/local/bin/wx-config=20
   (or wherever it is you installed wxWidgets 2.6.2)

2. For wxWidget's configure on the Mac, you must also
   pass --disable-shared.

   This is not related to problem you are having yet; just warning you
   in advance.  If somebody could explain why this is neccesary, that'd
   be great.  All i know is that it avoids things blowing up

3. As for the compilation error, either:
    A) wxWidgets should be configured --disable-unicode=20
    B) *or* you should patch wxhaskell using the following:
       http://www.loria.fr/~kow/download/patch-wxhaskell-unicode-05

High, Wouter!

This is a unicode problem: when configuring wxWidgets with
--enable-unicode "wxChar" is not "char". So you should rebuild
wxWidgets with --disable-unicode or apply the great patch from Eric Y.
Kow to wxhaskell (look for his posts on this list).

Hope this helps.

Thanks for all the help!

There are all sorts of things going a bit awry. Arthur Baars pointed  
out that Tiger comes with a built-in wxWidgets for wxPython. That was  
explained the odd version mismatch I was getting.

So far, I've rebuilt wxMac, disabling unicode and with the disable  
shared flags. Then I configured wxHaskell with the right wxWidgets:

 >./configure --wx-config=/usr/local/bin/wx-config

I no longer run into the unicode problem - but now receive the  
following message:

Does this ring any bells? More configuration problems? Note that by  
default, I'm using gcc 4.0.

Thanks again you guys,

Oh yeah,=20

I had that problem too and silently suppressed it in my -05 patch.

The basic problem is that wxColour::GetPixel behaves differently
on different platforms.

I've found that editing the file wxc/src/ewxw/eljcolour.cpp and
commenting out altogether the wxColour_GetPixel function helps.
