Hi emacs gurus,

            I'm wondering if you would help me with an emacs GUI issue I have recently when I installed emacs 23.2 for use by our financial engineering group.

            [Problem]

            $ DISPLAY=sbtorsvr329:23.0; export DISPLAY
$ /usr/local/bin/emacs
ld.so.1: emacs: fatal: relocation error: file /usr/local/bin/emacs: symbol rsvg_handle_get_dimensions: referenced symbol not found
Killed

$ DISPLAY=sbdevsvr286.dev:148.0; export DISPLAY
$ /usr/local/bin/emacs                               --> successful

We use the emacs and dependent packages compiled by sunfreeware.com (SMC* packages) for Solaris 10 sparc.
The problem I have with GUI emacs lauch  is that the success depends on the display set. It will launch fine for one display but crash for the other.
As you can see below, when the display is set to sbtorsvr329:23.0, the dynamic linker try to resolve the symbol rsvg_handle_get_dimensions, which is not defined in librsvg-2.so.2 being used, therefore it crashes;  however, when  the display is set to bdevsvr286.dev:148.0, the dynamic linker never try to resolve that symbol, as such, the GUI successfully gets launched:

--------------------------
$ LD_DEBUG=audit,reloc,symbols
$ DISPLAY=sbtorsvr329:23.0; export DISPLAY
$ /usr/local/bin/emacs 2>emacs.disp=sbtorsvr329:23.0                                                       --> emacs GUI crashed

$ grep rsvg_handle_get_dimensions emacs.disp=sbdevsvr286.dev:148.0
--------------------------

$ ldd /usr/local/bin/emacs|grep librsvg
        librsvg-2.so.2 =>        /usr/lib/librsvg-2.so.2

The above library is installed with SUNWgnome-base-libs package and doesn't contain the definition for symbol rsvg_handle_get_dimensions:

$ ls -l /usr/lib/librsvg*
lrwxrwxrwx   1 root     root          18 Oct 17  2006 /usr/lib/librsvg-2.so -> librsvg-2.so.2.5.0
lrwxrwxrwx   1 root     root          18 Oct 17  2006 /usr/lib/librsvg-2.so.2 -> librsvg-2.so.2.5.0
-rwxr-xr-x   1 root     other     112408 Dec 15  2004 /usr/lib/librsvg-2.so.2.5.0

$ echo $LD_LIBRARY_PATH
/usr/lib:/usr/lib/X11

$ /usr/ccs/bin/nm /usr/lib/librsvg-2.so.2 | grep rsvg_handle_get_dimensions                                            --> return empty


The behaviour that emacs resolve the rsvg_handle_get_dimensions symbol for one display but not for the other is really a mystery for me.

Continuing investigation, if I add path /usr/local/lib before /usr/lib, then the rsvg_handle_get_dimensions error doesn't appear since the librsvg provided by SMClrsvg contains the definition for the symbol, but then, emacs crashes with /usr/local/lib/libgtk-x11-2.0.so.0.1200.0 segmentation fault:

$ LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/usr/lib/X11; export LD_LIBRARY_PATH
$ echo $DISPLAY
sbdevsvr285.dev:148.0

$ ldd /usr/local/bin/emacs|grep svg
        librsvg-2.so.2 =>        /usr/local/lib/librsvg-2.so.2

$ /usr/ccs/bin/nm /usr/local/lib/librsvg-2.so.2 | grep rsvg_handle_get_dimensions

For most of the graphics libraries, there are two versions: the native SUNWgnome-base-libs version located in /usr/lib and SMCgtk version from sunfreeware.com located in /usr/local/lib:

$ ls -l /usr/local/lib/libgtk-x11*

lrwxrwxrwx   1 root     root          26 Apr 21  2009 /usr/local/lib/libgtk-x11-2.0.so.0 -> libgtk-x11-2.0.so.0.1200.0

$ ls -l /usr/lib/libgtk-x11*
lrwxrwxrwx   1 root     root          25 Oct 17  2006 /usr/lib/libgtk-x11-2.0.so -> libgtk-x11-2.0.so.0.400.9
lrwxrwxrwx   1 root     root          25 Oct 17  2006 /usr/lib/libgtk-x11-2.0.so.0 -> libgtk-x11-2.0.so.0.400.9
-rwxr-xr-x   1 root     other    3617016 Dec  1  2009 /usr/lib/libgtk-x11-2.0.so.0.400.9

SMCemacs 23.2 requires SMCgtk  2.12.0, which means the correct version of library was loaded.

I was thinking to try the native libgtk-x11 library, to do this, /usr/lib has been be put before /usr/local/lib, but then it will hit the rsvg_handle_get_dimensions error again.

Can someone please help?
