This is the old Squeeze based Debian?

No, we're going to leapfrog to Jessie for this.


Granted, *.deb is a much used package manager for debian and derived
distros. Will any other distro package managers be developed? I assume the
answer is no so, will OS developer submissions of other package manager
formats be accepted?

Let's worry about getting one to work... if we're wildly successful with
that and there's a good reason to do something else, we'll discuss it.

I'm not sure yet what to make out of this change, as we possible need
to see a deb to see
about some of the consequences. Just a few thoughts:

- Standalone is afaik broken since a long time, for example there is
missing FindXXX.cmake
files for various packages.

- As far as I know are there no system packages for (at least) glod,
colladadom, breakpad and cef.

- Some distributions only ship openjpeg2, not 1.4 or 1.5 (for example
I cannot find anything older than 2
for Debian Wheezy). Possibly this can be worked around with non
standard deb repositories in apt.conf.

- Compiling the deb eg on Squeeze and trying to install it on
something Wheezy based could lead to
interesting results, due to the dependent packages from the Squeeze
system being recorded in the deb.
(Or compiling on Wheezy and installing on Jessie and so on).

- VLC: Henri pointed out a few times, that the VLC api is not exactly
stable between releases.

- Boost will be interesting


Well, if it was easy it wouldn't be any fun, would it?

Many such files are actually part of the cmake package or added by the
devel packages of some libraries.
See: /usr/share/cmake/Modules/Find*

I resolved the "STANDALONE" (now "SYSTEMLIBS") issue for my viewer by
making it so that libraries that are not likely to be present in distros,
or not properly patched for SL viewers, or simply incompatible, are still
downloaded as the pre-built viewer libraries (i.e. the resulting viewer
binary is linked against a mix of commonly available system libraries and
exotic/patched pre-built libraries). It more or less works, i.e. it works
on my system (PCLinuxOS) but one of my users encountered an issue with
this method recently (probably because of his distro's curl library,
which I will probably mark as "use-pre-built-curl-only" in future
releases).

Your best bet is however to keep building the viewer using the pre-built
libraries and packaging it together with them (/usr/games/YourViewerName
is a good candidate for the packaged build destination).

Gstreamer would be better... I would have pointed you to the archived
messages on this list in which I went to great extents to explain
everything in details, but the archive is currently down...

> - Boost will be interesting

You cannot currently using system boost libraries: they lack LL's custom
coroutine stuff...

I think what you're encountering is that there is no longer a 'darwin'
platform in viewer64/autobuild.xml, only 'darwin64'. If you use 'autobuild
configure -A 64' (or leave AUTOBUILD_ADDRSIZE=64 set in your environment)
it should work.

/me steals popcorn in Monty's box, and speaks with a mouthful.

/me chewing, "Ya know..."
/me gulps, "Excuse me..."

All it takes is writing a shell script allowing to build your viewer.
Then packagers just have to invoke that script via whatever package
build system you use (rpm, deb, ebuild, you name it).

/me steals another handful of popcorn and points at his viewer sources
