Hmmm from what I understand, wxWindows basically says that I do NOT have to distribute the source of OSG & Producer with my dynamically linked app. But since OpenThreads uses just LGPL, I do have to distribute its source. Is it sufficient to include a README notice that directs the user to the OpenThreads website?
AFAIK, no. Unfortunately, if you are distributing something (L)GPL licensesd (i.e. the OpenThreads DLLs) you must make the source available. Pointing the user to the upstream vendor is *not enough*. Some Debian-derived Linux distro vendors learned this the hard way recently.
Jan is technically correct in that you must make the source available. A web link is technically not sufficient. But you do have some wiggle room. According to the license (warning: I haven't read it in a long time so I could be mistaken and IANAL), you only need to make source code available upon (written?) request. I believe you are also allowed to charge a nominal fee (for shipping/handling). So if you choose, you could not include source with your deployed binaries. But upon request, you would be obligated to mail them a copy of the source. In practice, this usually doesn't happen because it is much easier and faster to follow a web link. But there are some real jerks out there testing your full compliance with the license. Personally, if this were to happen, I would look into the clauses about the fee and see if I could charge a lawyer sized hourly rate to cover your time/effort. So your options are: 1) Just ship all the binaries and hope nobody is a jerk and requests the source directly. (If they do, you must comply, but make the fee cover your costs and time.) A web link is sufficient for most people. 2) Ship the binaries and the source together. (If you ship on physical medium, you might have enough space left over.) 3) Don't distribute the dependencies yourself and make the user download them (or compile them) themselves. (This is obviously inconvenient for end-users.) -Eric _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
