RE: Grace (xmgrace) 5.1.12-1 graph program -- building under cygwin -- possibly LessTif bug from 0.93.91 ?

["Atwood, Robert C" <r dot atwood at imperial dot ac dot uk>]

Sorry, I guess you missed the more detailed description, gdb backtraces,
etc? I shouldn't have change the subject to BACKTRACE: 



When certain dialog boxes are opened, including (but not only)
'Plot|Axis properties ...' the program crashes.
Opening some other boxes eg 'Plot|Plot appearance ... ' does not cause
the crash.
Double-clicking the axis causes the crash.

The console in which it was running reports that it got SIGSYS  and says
it may have something to do with the graphic (but I think that is
because the signal numbers are different? GDB says it gets SIGSEGV
segmentation fault)

The back trace with 5-1-12-1 rebuilt with debug (-g) is copied below.
But LessTif seems not to have been build with -g and I am having trouble
building this myself.

The same behaviour occurs with the new 5-1-14 package and the new
LessTif-0-93-91-6 , so my guess that it was the same bug in XGetCValues
that I encountered in November may be totally wrong. 

Which LessTif did you install and get it to work? Did you try opening
some dialog boxes or just start the test routine? The test routine works
because it never opens those dialog boxes.

Hi!

Yes, I made the package yesterday, and I didn't write an announcement
yet. I could just recreate your "crash", it said "cygXm-2.dll" is
missing. After installing lesstif it works.

I'm sorry for that, I'll report to cygwin-apps now and add the
dependency to the setup.hint file. Besides this small problem xmgrace
seems to work. For me.

Can you describe what "crash" you are seeing? It doesn't sound like an
alert box saying a dll is missing.
