Glad to hear you're trying the Mac build. As you've found, we haven't
been able to spend as much time on the Mac version as we have on the
Linux version. The Mac version needs more contributors - like you,
The problem with GetSvnVersion is my fault. I had to remove that
function temporarilly to get the Universal Binary version of libCDraw
to build. I'll check-in a fix shortly.
I'll try to fold your comments into the Mac build instructions when I
I have created an ad-hoc "External makefile" project in XCode which
works OK but I'm not sure whether I've done it the best way. I guess
that Xara LX may always have to be built using a makefile but it
would be much better to develop using a "proper" XCode project.
When you get the Mac version running you will find the most obvious
problems are that (1) you get some warnings when loading files and
(2) some objects don't render correctly.
1. I'm 99% certain this is because of byte-order problems in the
CXaraFile::Read(FLOAT*) and CXaraFile::Read(double*) functions.
2. This may follow from 1 but may be something more fundamental in
the rendering of transparent bitmaps.
Thanks for the feedback.

I'm guessing that this is defined in the recently checked in
libCDraw.a because I see a prototype but no implementation for it
anywhere. I had to run ranlib on it because ld was complaining
about an out of date table of contents. I know that libCDraw.a is
a fat binary because I had to upgrade from XCode 2.1 to 2.2 to even
be able to get this far (2.1 can't handle the Mac/Intel universal
binaries), so I was thinking that might have something to do with
it. I am developing on a G4 PowerPC chip. This latest build
attempt was made with revision 685 from subversion.
I have collected some notes about some things that I have
encountered and thought I would share them to save others some
pain, or at the very least someone can tell me if I've
-Gettext is out of date in Fink. I abandoned Fink and just built
gettext and automake myself. You have to configure gettext with "--
-GTK is not included in the Apple developer tools nor is it
necessary. wxWidgets uses Carbon by default. You can configure it
to use Cocoa, but that is currently beta. I actually attempted to
build GTK before realizing this and none of the examples even
worked. I've gotten GTK apps to work before on the Mac, but I used
Fink binaries. This little adventure is where I discovered the
jpeglib issue listed below.
-The IJG distribution of libjpeg does not build correctly using the
standard procedure. Everything appears to work fine and the tests
even run without any errors, but other packages will fail to
recognize the resulting binaries. I found the following
instructions online that corrected this problem:
tar zxvf jpegsrc.v6b.tar.gz
cp /usr/share/libtool/config.sub .
cp /usr/share/libtool/config.guess .
./configure --enable-shared --enable-static
sudo make install
sudo ranlib /usr/local/lib/libjpeg.a
-There is some confusion in the build instructions with wxWidgets
versions. The latest wxMac source is version 2.6.2. You have to
get the full source if you want the 2.6.3 RC1, although wx-config --
version still reports it as being version 2.6.2. I am using 2.6.3
-The error tracking code in wxOil/errors.h and wxOil/errors.cpp
that uses wxStackWalker is a problem on the mac. wxWidgets
configure reports that the backtrace() method is not available and
warns that this functionality will be disabled. I surrounded the
small amount of code that uses the wxStackWalker class with
"#ifndef __WXMAC__" as a temporary solution to get the build going.
-You have to add "--enable-debug" to the XaraLX configure command
if you are using a debug wxWidgets build as specified in the build
instructions. If you don't do this, wx-config will not be able to
retrieve the proper settings for CPPFLAGS.
Has anyone attempted to create an XCode project? I can look into
this after I get a working build if no one else wants to. I still
need to make my way through all the XaraLX documentation on the web
site, but if someone could give me some brief direction on what
current Mac issues I could start with and the areas of the code
where they exist, that would be much appreciated.
I hope everyone is having a great weekend,
