[osg-users] Dependencies on openscenegraph.org SVN

Hi all,

We've been discussing the best way to distribute the Visual Studio 2008 
dependencies binaries in another thread, and we'd like to have a general 
solution, so I thought it was time to move the discussion to its own 
separate thread.

What I'd like to suggest is to put these on the openscenegraph.org SVN 
in some separate directory from the OSG sources (so it could be checked 
out separately). Note that path names I give here will be just my 
suggestions and I'm open to different ideas.


Say we start this out at this path:


 From there we could have the platform:

OpenSceneGraph-binaries/osx32 (or darwin32? or ...)

Then, say for win32 (which will be the first candidate for this, so the 
first to be fleshed out):


where vs80sp1 would then be similar (identical?) to Mike's repo at

The base platform repos could contain the releases and any other 
platform-specific files we want to place there. Since we can access that 
svn repo from a web browser, the releases being there would mean that 
they could be downloaded as easily as from 
http://www.openscenegraph.org/downloads/, so we would just need that.

If we just want to use this scheme for dependencies for now, I would 
suggest changing OpenSceneGraph-binaries to OpenSceneGraph-dependencies 
and dropping the dependencies directory level.


The other thing that this would allow us to do is to assign maintenantce 
of the different parts of the repo to different people, depending on who 
has the interest and tools to compile and test the dependencies. The 
next question is who would be willing to step up and maintain these. I 
suggest to start with:

vs71: ? (I know Adrian Egli is one of the people who use this compiler, 
perhaps you would be interested Adrian?)
vs80sp1: Mike Weiblen (since he already does it on his site...)
vs90: Matthias Helsing (since he's offered his binaries for this version 

Now, for other platforms, I'm open to discussion as to what would be 
useful to put in this kind of structure, and who would be interested in 
doing such a thing. On Linux at least, I think most people just get 
their dependencies from their distro's package manager, so dependencies 
are a bit of a non-issue, but maybe other things could be put there? 
(other than the release binaries) What about MacOS X? Do you need to 
download and compile 3rd party dependencies on that platform or do you 
just get them through Fink?

On a related note, I assume someone has already compiled the 
dependencies for win64 and has just not offered to distribute them. 
Would someone step up and want to maintain the win64 part above (either 
for vs80sp1 or vs90 or both)?

Thoughts? Comments?
