[developers] Logon on Ubuntu 10.04

I think what we see now is a different problem.  The 64-bit yzlui I have appears to be up-to-date, and was working fine on my 64-bit machine until this most recent Ubuntu version.  I don't get any complaint about shared object files with yzlui, but as I mentioned, it crashes when asked to show a feature structure, unfortunately without any visible complaint.

I'm pretty sure I've got detailed notes in the course forum for UW 2009 LING567. Looking through the archives now... 

Ah... there it is. The error I got was: 

LKB(12): (lui-initialize) 
LKB(13): /home/cjac/delphin/lkb/bin/linux.x86.64/yzlui: error while loading shared libraries: libgtk-1.2.so.0: cannot open shared object file: No such file or directory 
[NIL] lsp-loop(): premature end of file (read 1 characters) 

And I found the 64-bit yzlui library at 




Download that binary and replace the one you have under $DELPHINHOME/lkb/bin/ 

I think the issue is documented here:

Yes, I'm on a 64-bit machine, but don't know where to obtain a 64-bit version of pangolui different from the 32-bit version (the two executables in logon/lingo/lkb/bin/linux.x86.[32|64] are apparently identical).

I also tried (lui-initialize :lui "yzlui") which works a little better (for English) than (lui-initialize :lui "pangolui"): it succeeds in displaying parse trees, the parse chart, and indexed MRSs, but it crashes upon being asked to display AVMs or simple MRSs.  Unfortunately, the file /tmp/yzlui.debug.danf does not supply any clue about what goes wrong with AVMs.  All I see is the following Lisp message (the same one that pangolui produces when it crashes):

[NIL] lsp-loop(): premature end of file (read 1 characters)

I think I recall this problem... Are you perhaps running on a 64-bit machine? If I recall correctly, you need to replace the binary in the distribution with a 64-bit version.

Dear all,

I am having a bit of a problem running LKB from the LOGON distribution
properly. It seems to load well, and loading a grammar is also no
problem. However, when parsing, things go south:

[NIL] lsp-loop(): premature end of file (read 1 characters)

When trying again, I get the really old-fashioned graphical
representation. Issuing the command (lkb:lui-initialize) works, it
even shows some parse tree after parsing a new sentence, but crashes
when doing a mouse-over.

Is this a known problem, hopefully with a known workaround?
