Re: [geomview-users] Geomview on Cygwin

[Lloyd W. <llo...@ya...>]

Thanks, Ken!

Here's the official Cygwin announcement of Ken's
Geomview 1.9.5 package:
https://cygwin.com/ml/cygwin/2017-06/msg00258.html

and the attached screenshot shows the packages in the
gui of the Cygwin installer. Ken got Geomview working well
on both 32-bit and 64-bit Cygwin.

On Geomview modules - a month back I refreshed the list of
third-party modules to see what was still out there:
http://www.geomview.org/thirdparty/
fixing broken links etc.

Other than the previously-with-Geomview modules Ken mentions,
and the Geometry Center's Orrery, there are two modules
that could also be packaged for Cygwin, as they also run
separately standalone and can be useful by themselves when
not controlling Geomview:

- SaVi http://savi.sourceforge.net/ - needs a make install though
(disclaimer: I try to maintain this. I'm quite biased about it.)

- Cornell's DsTool - some notes at:
http://personal.ee.surrey.ac.uk/Personal/L.Wood/software/DsTool/
on where DsTool is at.
DsTool can run under 32-bit Cygwin with Tcl 8.5, but would need
some attention to bring it up to date for 64-bit and/or Tcl 8.6.
And a make install. (Disclaimer: it's a forerunner/compatriot of
SaVi, tested out a lot of Tk interface code in SaVi.
I'm quite biased.)

There are a bunch of other modules that used to be packaged
with much older versions of Geomview as demonstrations; they're
listed in the old FAQ at:

http://www.geomview.org/FAQ/answers.shtml
"What modules are shipped for which platforms with the current release?"

but I've got no idea where they're at. (I always had a soft
spot for gvclock as the most complex on-screen clock I
could find. xclock has nothing on it...)

I"ve no clue about crayola or labeler

thanks and regards,

Subject: [geomview-users] Geomview on Cygwin



I have recently added geomview-1.9.5 to the Cygwin distribution.  I have 

also built (but not added to the distro) all the emodule packages 

mentioned in the README in the geomview source tarball:


* gvemod-cplxview

* gvemod-crayola

* gvemod-labeler

* gvemod-ndview

* gvemod-xforms-example

* gvemodules-xforms

* maniview


If anyone wants to try these, they can be obtained via Cygwin's setup 

program from my personal Cygwin repository:


  http://sanibeltranquility.com/cygwin/


There are instructions at that site.  Note: I have other packages there 

that you probably don't want to install, so be careful to just choose 

the emodule package(s) that you want (and let setup install any 

dependencies).


Most of the emodules seem to work OK, in the sense that something 

reasonable happens when I click on them in the emodule list.  (I'm not a 

geomview user, so I can't really test them properly.)  But there are a 

few glitches:


1. Clicking on "Crayola" yields the following error message in the 

terminal from which I started geomview:


Error in startup script: invalid command name "Ïúíþ`"

     while executing

"Ïúíþ`   H__PAGEZERO..."

     (file "/usr/libexec/geomview/tcl/Crayola" line 1)


This is due to the fact that /usr/libexec/geomview/tcl/Crayola is a 

binary file, not a Tcl script:


$ file /usr/libexec/geomview/tcl/Crayola

/usr/libexec/geomview/tcl/Crayola: Mach-O 64-bit x86_64 executable, 

flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|PIE>


2. The same thing happens with "Labeler".


3. Clicking on "NDdemo" yields


   sh: /usr/libexec/geomview/nddemo: No such file or directory


And indeed the gvemod-ndview sources do not contain a source file for 

nddemo or a Makefile rule for building it.


I assume all of these glitches are problems with the packaging of the 

emodules, but please let me know if there's something I can fix in my 

builds.
