[Help-gsl] Source code for HiCalc / breah of GPL for GSL

[Dr. David Kirkby]

Hi,
It is clear that the scientific calculator 'HiCalc' which runs on PocketPC


http://www.ppclink.com/?ppclink=product&do=view&id=44

uses the GNU Scientific library. You make no secret of that fact. It is 
*very* clear from this screen shot.

Now the GSL is released under the GNU General Public license as is 
cleared stated at:

http://www.gnu.org/software/gsl/#licensing

That is released under the GPL and so HiCalc must be released under the 
GPL too. Yet it would appear HiCalc is closed source. There is no option 
to download the source code from the HiCalc web site and you charge a 
registration fee to use the calculator. This is clear from this screen 
shot.

Hence the obvious question is to ask whether you will change the license 
 on HiCalc from its current on to the GPL and release the source code 
as you must do.

I am copying this email to one of the GSL mailing lists who I am sure 
would be interested about closed source software using a library which 
is distributed under the terms of the GPL.
