Hello,
Glad to see that CGLAB is back for Scilab 5!
Is a distribution for Windows planned?
Read you soon
Samuel

Hello Samuel,
I'm very happy that you like my piece of code!  Windows is not my strong side, so I hope
for 
someone from Scilab to create distibution for Windows :-)

Thanks for providing a greatly needed tool.

Unfortunately, it is not properly loading on the Mac OSX with Lion.  It successfully
downloads via the ATOMS manager, 
but when Scilab is restarted the follow error is noted:


Start CG-lab
	Load macros
	Load gateways
atomsLoad: An error occurred while loading 'cglab-2.0-1':
	link: The shared archive was not loaded: dlopen(/Applications/scilab-5.4.0-alpha-
1.app/Contents/MacOS/share/scilab/contrib/cglab/2.0-1/sci_gateway/c//../../src/cpp/libcgal_cpp.dylib,
10): image 
not found


Could there be a misspelling error in the file that it is looking for?

Your help would be very much appreciated.

Craig

Comment from Craig Denman -- July 1, 2012, 07:43:51 PM

I wanted to add a few comments to my note above:  1) I tried using Scilab-5.4.0-beta-1 and
Scilab-5.4.0-alpha-1 with 
OSX Lion, both from the same computer and both failed with the same problem.  It was also
tried on a computer with 
OSX Snow Leopard and Scilab-5.3.3, also failed with same error.

Help to resolve would be appreciated,

Craig

Hello Craig,
I am really sorry, but I cannot help - I don't have any possibility to access OSX or any 
other Apple OS.

Comment from Craig Denman -- July 1, 2012, 08:38:00 PM

Edyta,

Thank you for responding to my need.  Am I able to help by compiling on my system?  I have
looked at the CGAL site 
and found instructions on how to install CGAL, but I am not sure about how to compile your
ATOMS module.  Should I 
consult the Scilab compile instructions as a start?

I have macports installed and noticed a CGAL installation there -- could this be of any
help?  I also have all of the latest 
Xcode installed.

Please let me know if compile instructions are available and point me into the right
direction.

Thank you for your help,

Craig

This is a follow-up comment:  I tried loading cglab into a Ubuntu 12.04 linux version 
running Scilab 5.3.3 but without luck.  I first installed CGAL and then tried installing, 
via Atoms, the cglab and received this error message when restarting Scilab to load the 
module:

Start CG-lab
	Load macros
	Load gateways
atomsLoad: An error occurred while loading 'cglab-2.0-1':
	link: The shared archive was not loaded: libCGAL.so.5: cannot open shared object 
file: No such file or directory

I hope that this information can help to fix the problem.  CGLAB is an important toolbox 
for Scilab allowing the use of the CGAL library.

Any help to resolve this would be much appreciated.

Thanks,

Craig

Dear Scilab and CGLAB tool administrators,

The CGLAB Toolset is very important for our project. At this point, however, I have not
been able to get the CGLAB
toolset to load -- please see my other posts above for the errors.

I have been aware of the "parallel" forum for CGLAB on the forge.scilab.org site,
but until the most recent posts it
looked "dead." I see that others are having the same problems -- and are not
able to get CGLAB to work.

It would be very helpful if the CGLAB description made it clear as to what version of
Scilab was used for the last
successful load of the CGLAB tools. Also, assuming that CGAL must be first installed
(since it does not mention
whether it is included as part of the toolset), what was the version of CGAL that last
provided a successful load of the
CGLAB tools. If I was to make a guess, it looks like Scilab 5.2.2 and CGAL 3.8 since the
toolset was created in Aug
2011 -- but why am I having to guess?

I have tried installing on Mac 10.7 Lion, 10.6 Snow Leopard, and Linux/Ubuntu 12.04 systems
without success. I
have tried going back to an archived/older version of CGAL, but I have not been able to
compile on the Mac -- too
many errors.

At this point of putting hours of effort into trying to get CGLAB to work -- without having
the all of the details of the
conditions where CGLAB last loaded into Scilab successfully -- I have to say that the
toolset does not work.

** Please escalate the efforts to fix the CGLAB toolset for the currently available
versions of Scilab and CGAL.

Because the Delaunay triangulations are required in our project, if they are not available
to Scilab we will be forced to
return to using Matlab. We are strong believers in Scilab and have made every effort to
convert our programs over
from Matlab.

Every effort put into getting the CGLAB toolset to work is very (VERY) much appreciated.

Thank you,

Craig

Hello Craig,

I don't think that cglab has been much tested under Mac OS X.
However, did you try to rebuild it yourself from the sources ?

I just pushed some fixes for the Scilab 5.4.0 release


Sylvestre

Comment from Sylvestre LEDRU -- July 20, 2012, 03:02:50 PM

I published a new release (v 2.1) including these fixes:

Hello,
> I am using Windows 7 32 bit operating system and scilab 5.5.1

As indicated in the "Detail" section at the top of this page, under the item 
"ATOMS packaging system Available on", CGLAB is available only for Linux and
MacOS
operating systems, not for Windows.
