Re: [Fwd: Re: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for GLPK/Java]
OptimJ does not link to glpk. To use glpk you download an examples set which includes a directory 'OptimJ samples - GLPK Binaries' which contains a compiled glpk 4.36 dll and a java jar file. The source to produce the java jar file is included in 'OptimJ 1.3.10 samples - GLPK\OptimJ samples - GLPK Binaries\src\com\ateji\optimj\glpkliba\LibraryLoader.java'. All the code and information to upgrade to glpk 4.45 is openly available. A better implementation would be if OptimJ provided an 'abstract java interface' which worked with any complient implementation, which could include glpk-java (using swig) or iajaar (not using swig) or their example (not using swig). - Original Message - From: Xypron xypron.g...@gmx.de To: chtimax maxcach...@gmail.com Cc: help-glpk@gnu.org Subject: Re: [Fwd: Re: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for GLPK/Java] Date: Wed, 19 Jan 2011 19:56:05 +0100 Hello Max, what is the license status of the generated code?

They kindly send me what is probably a Microsoft Windows security key, judging by the file extension, its binary contents, and their description, plus instructions for downloading the main archive. I think the Ateji team is being a little disingenuous on this one -- see the forwarded message immediately below. As far as I can tell, the free 'OptimJ' version is only free in the sense that no money changes hands -- it is not free in the Free Software Foundation sense: http://en.wikipedia.org/wiki/Free_Software_Definition I am not suggesting that Ateji is breaking the GNU GPLv3 through this process -- although I have no special knowledge in this regard. But it would help if Atieji could word their communications with a little more precision -- in particular, their response to Larry D'Agostino's inquiry, in my view, could be interpreted as misleading. best wishes Robbie To: help-glpk@gnu.org Subject: [Fwd: RE: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for Message-ID: 1295349022.3392.0.camel@none From:Andrew Makhorin m...@gnu.org Date:Tue, 18 Jan 2011 14:10:22 +0300 Forwarded Message From: chtimax maxcach...@gmail.com To: Help-glpk@gnu.org Subject: RE: [Help-glpk] ANNOUNCEMENT: OptimJ solver link for GLPK/Java Date: Tue, 18 Jan 2011 01:30:21 -0800 (PST) Coming back to Larry's question below, we have recently taken the decision to contribute OptimJ to the free software community.
