xmgrace not working on OS X Leapord

[okhalid.cern@…]

Hi,

I have installed grace-5.1.22 on my machine. Macports successfully installed Grace and i can locate it, man pages work so does the command line grace interface.

But when i launches xmgrace from the console, it fails with the following error:

dyld: Symbol not found: __cg_jpeg_resync_to_restart
  Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO
  Expected in: /Users/okhalid/usr/local/bin/MacPorts-1.7.0/lib/libjpeg.62.dylib

Trace/BPT trap

Thanks for your help. Regards

Omer

xmgrace works fine for me on Leopard. Did you install macports into a non-standard directory? if so, what is it? I have libjpeg.62.dylib at:

/opt/local/lib/libjpeg.62.dylib

Also, what does the following command return:

port installed grace jpeg

I re-installed macports under standard location and now there is libjpeg.62.dy under /opt/local/lib/

It's also available under: /Users/okhalid/usr/local/bin/MacPorts-1.7.0/lib/

Also, what does the following command return:

port installed grace jpeg

I did the same as before; just re-installed every thing...

I think the problem is with the libjpeg. The installed version by macports is jpeg @ver7_b3 and my guess is that there is a bug in it which is crashing due to ]dyld: Symbol not found: cg_jpeg_resync_to_restart

How can i install another and stable version of libjpeg via macports?

[okhalid.cern@…]

I have checked on the www.ijg.org . libjpeg version 3.6b is considered stable since Mar 1998...so I am not sure about my theory about the bug in it :-S

hmm...it might be due to my OS X 10.5.5

Any body else saw the same problem?

[okhalid.cern@…]

I found the source of problem. There is a libJPEG.dylib on my system already which is actually conflicting with the libjpeg.dylib from macports.

Now I have tried this in my ~/.profile and ~/.basrc : export DYLD_FALLBACK_LIBRARY_PATH=/opt/local/lib:$DYLD_FALLBACK_LIBRARY_PATH It does not work :-(

I have renamed the libJPEG.dylib to libJPEG.dylib under: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources

And then created a symbolic link in there to /opt/local/lib/libjpeg.62.dylib

But no luck! Any more ideas?

grace works fine on my machine as well.

I wonder how any library found
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libJPEG.dylib.

What is the result of

otool -L /opt/local/bin/xmgrace /opt/local/lib/libjpeg.62.dylib

?

You should not set DYLD_FALLBACK_LIBRARY_PATH. It is not necessary and can cause problems.

I have renamed the libJPEG.dylib to libJPEG.dylib under: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources

You should not change anything in /System. This will likely cause problems for your operating system. You should change it back to the way it was.
