[sldev] Working on an installer, anybody figured out licensing yet_

[dale at daleglass.net]

Hiya :-)

I've been working on an installer again. Previous approach was ugly and
required .NET, so I got rid of that.

Instead I decided to tackle two problems at once: Redistribution
restrictions, and updates.

Both are solved in the same way:

Installer just carries a file list with it, with filename and MD5 sum.
When you install, it checks whether the file is already there. If not,
or the md5sum is wrong, it checks all SL installs and tries to find it
there. If not, it downloads.

The files that can't be redistributed aren't on my server, so if they're
needed and can't be found locally, the install fails.

All this is coded in NSIS with a MD5 and a file decompression plugin.

This way, even the first install of my version of the viewer will grab
already installed files, and further updates will be just what changed.
No more 25MB downloads.


Now, I'd like to make my installer include as many files as possible to
make sure it doesn't need very specific official SL versions to be
installed.

So, anybody figured out what can be redistributed yet? If so, a wiki
page on it would be very helpful.

A number of DLLs in the package don't come with the source, but I think
that some of them must be redistributable.

These are the files in the main directory:

dbghelp.dll, msvcp71.dll, msvcr71.dll: Microsoft runtime stuff, I assume
redistributable.

fmod.dll: Not sure, might be. Could be specifically downloaded from the
fmod website, I suppose.

freebl3.dll, js3250.dll, nspr4.dll, nss3.dll, nssckbi.dll, plc4.dll,
plds4.dll, smime3.dll, softokn3.dll, ssl3.dll, xul.dll: Mozilla stuff,
given the Mozilla license I assume they're redistributable.

app_settings/mozilla: I assume redistributable

xpcom.dll, gksvggdiplus.dll: Definitely redistributable, license stated
as "License: MPL 1.1/GPL 2.0/LGPL 2.1".

llkdu.dll: Apparently not redistributable. 

So, at first glance, except llkdu.dll and perhaps fmod.dll, everything
else should be fine to redistribute?


Questions for LL:

Other than library redistibution restrictions, what other things are
there to have in mind when releasing a custom viewer?

Can I just package the results of the complication as-is, or do I need
to do something more?

For example, can I leave the SL icon as it is, or I'd have to have my
own branding?

Should my viewer identify itself as a third party viewer to the grid?

Do I need to remove or disable anything (crash reporter, for example)?
