[comp.lang.eiffel] eiffel in X -- does it work?

thomas@falcon.bcm.tmc.edu (11/21/89)

Here's a repeat of my request which got no response--
(am i the only one trying to use the Xwindow classes of Eiffel???)

i am running X11r3 on a Sun 3/60 with OS4.0

when i try to run the Eiffel browser "good", it gets an immediate
segmentation fault.
When i try to run the examples provided by ISE, they get various
exceptions.. when i try to fix an exception, another appears not
far along in the code...
is it me, or ISE, or none of the above? so far no reply to my
direct request to ISE.
Thanks.

  I thought I was the only one using the graphics library.  I assume you
  are using Eiffel 2.2.  I had the same problem -- the demos did not work.
  I called ISE several times and they finally found a bug in pass 2 of the 
  compiler.  The demos don't give exceptions anymore, but they don't run
  very well either.  The demo that is supposed to draw all the shapes on the
  screen does not work well at all. ISE said that they know this and have a 
  better version they would send me.  Have not seen it yet.  There have also
  been a couple of fixes posted on the net.  I suggest calling ISE (I never
  have any luck with e-mail) and talking to Jean-Marc Nerson.  Tell him you 
  want all the fixes to the known bugs.
