why is gdk_font_equal symbol not found in libgtk-x11-2.0.so.0?

["Will Boyd" <javafreelancer gmail com>]

hello all,

my investigation of the gtk/eclipse issue that i reported here:
    https://bugs.eclipse.org/bugs/show_bug.cgi?id=177949#c13

lead me to search for previously-installed versions of the gtk and its
dependent packages on my solaris 9 sparc sunblade 100. the
sunfreeware.com gtk packages that i recently updated were installed to
/usr/local/lib. however, a search for "*pango*.so*" revealed
previously-installed pkgs in /usr/lib as well (i am assumming these
came bundled with the solaris 9 os installation). 

as a test, i temporarily moved the pango libraries from /usr/lib and
started eclipse. from that test, i determined that eclipse was in fact
referencing the older, previously-installed versions of the gtk
packages. so in order to make eclipse refer to the most recently
updated gtk 2.2.4 packages that i dl'd from sunfreeware.com, i did the
following:

  1. export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
  
  2. java -Djava.library.path=/usr/local/lib eclipse ...
  
now, eclipse is - without a doubt - referencing the gtk 2.2.4 packages.
but, it is now failing to launch and reporting the following error:

   "ld.so.1: eclipse: fatal: relocation error: file
/usr/local/lib/libgtk-x11-2.0.so.0: symbol gdk_font_equal: referenced
symbol not found"
   
so, i ran the following ldd command:

   ldd /usr/local/lib/libgtk-x11-2.0.so.0.200.4
        libgdk_pixbuf-2.0.so.0

i also ran nm libgtk-x11-2.0.so.0

according to the following post from billy biggs, the gdk_font_equal symbol is supposed to be defined in libgtk-x11-2.0.so.0:
   
      http://dev.eclipse.org/newslists/news.eclipse.platform/msg44199.html
      
according to the output of ldd on my installation of gtk 2.2.4,
gdk_font_equal appears to be undefined in
libgtk-x11-2.0.so.0.      


i also ran nm libgdk-x11-2.0.so.0:

i appreciate that one workaround (compile gtk from source) was suggested by one eclipse developer:

   http://dev.eclipse.org/newslists/news.eclipse.platform/msg44228.html
   
and another workaround was suggested by another developer (reinstall solaris 9!):

   http://dev.eclipse.org/newslists/news.eclipse.platform/msg44317.html 
     
i am not a c/c++ developer. i would rather not have to spend days or
weeks , first learning how to compile c/c++ programs, then more days or
weeks debugging failed compilations. so please, can anybody suggest an
alternative, less-complicated workaround for the undefined
gdk_font_equal symbol not found in libgtk-x11-2.0.so.0? 


thanks in advance for your help.

many thanks,
