Thanks for all these clarifications !

[osg-users] OSG static linking for commercial application
Hi, This is a question about legal statement, not technical. I'm working on a commercial project based on OSG. I made a dynamic library 3dstuff.dll with all my 3D stuff, this DLL uses OSG. Can I use static linking of OSG with my 3dstuff.dll to distribute only this DLL with my executable file ? Or is it an OSG license violation and I have to distribute OSG as a set of dynamic librairies ? (osg.dll, osgGA.dll, osgXX.dll ) I ask this question here because I found this : The OpenSceneGraph Public License is designed to be compatible with use of proprietary applications, such applications can statically and dynamically link to the OpenSceneGraph and can be redistributed with the libraries free of charge. Your applications can be distributed under any license, be it open source or proprietary. at http://www.openscenegraph.org/projects/osg/wiki/Legal which seems to say ok, you can do that But in the complete license text, here : http://www.openscenegraph.org/projects/osg/attachment/wiki/Legal/LICENSE.txt I didn't find anything about static linking.

Re: [osg-users] OSG static linking for commercial application
Hi Albert, You can statically link the OSG libraries as they are all OSGPL based, a license which exists solely to enalbe you to embed or staically like OSG. Some of the plugins aren't OSGPL based so you'll need to take care with those, most are OSGPL though. Robert.

The relevant text is in the wxWindows exception #2 near the top: 2. The exception is that you may use, copy, link, modify and distribute under the user's own terms, binary object code versions of works based on the Library. Meaning that you are not required to distribute your own source code when you link it against OSG (either statically or dynamically). This is provided that you don't copy any code into OpenSceneGraph or your own code that is licensed as LGPL or GPL-only (as stated in exception #3). --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

This raises an old, but still relevant side issue. I imagine most people copy bits of working code from the examples into their applications and then modify it. Technically, for a closed-source app this is a license violation, but I believe that this is the very purpose the examples were intended for. Does there need to be a license amendment/exemption or something for the examples? -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL.
