[Gtk-osx-devs] Latest stable libxml2 fails build on OS X 10.4

[Richard Procter <richard n procter gmail com>]

Hi there,

Just a heads-up that libxml2 in the latest stable gtk-osx fails to  
build on OS X 10.4 - apparently because it relies on a recently  
publicised symbol in -lz. Details below.

regards,
Richard.

On 10.4:

[buildshell] orchid:~ rix$ nm /usr/lib/libz.dylib | grep gzdirect
9111a5cc t _gzdirect

On 10.5:

[buildshell] ~/gtk richard$ nm /usr/lib/libz.dylib | grep gzdirect
00008b6b T _gzdirect


Using this entry from jhbuild/modulesets/gtk-osx-bootstrap.modules:

<autotools id="libxml2" autogen-sh="configure">
     <branch version="2.7.7" module="libxml2-2.7.7.tar.gz"
             repo="xmlsoft.org"/>
</autotools>

Build error is:
