Agreed 100%

Though I have given up hope of LL ever changing their stance (based on 
some recent events). I wont say anymore because the temptation to also 
start a rant of my own on the subject is there. I think you pretty much 
covered it.

Maybe one day pigs will fly and LL will go back to providing a Linux 
viewer.

FreeBSD is not a build target for the viewer: beyond the need to rework
the build system (and corresponding #defines in the sources), you'd lack
all the pre-built libraries that the viewer needs.

Do not use Linden Lab's sources to try and build a Linux viewer: you
would invariably fail.

You can thank LL for not providing support for Linux; while they benefit
for free from all the work done by GNU/Linux developers and while SL
won't even exist without their work (especially on the server side of
things, but even the viewer is using a shitload of Open Source components
that have been primarily developed under and for GNU/Linux).
That's how LL is repaying the Open Source community when they could
just "devote" one developer to simply reuse the work TPV developers did
for Linux, and provide a Linux supported viewer.

Hell !  I've been maintaining (and vastly improving) my own viewer (and
not just for Linux) for the past 13 years, alone, and only on part of my
sparse free time: don't tell me a programmer at LL cannot maintain a
Linux viewer: all what it would take them (once their viewer is brought
on par with TPVs' Linux support) is just a couple of hours of work *per
week* !
[/rant]


Instead, try TPV sources. My viewer (Cool VL Viewer) builds with just a
single command under any Linux distro (just type ./buildlinux.sh in a
terminal pointing in the linden/indra/ directory).

It would also be a good candidate for a FreeBSD port: it got a stand-
alone build system (so adding FreeBSD to the cmake files would not be
an impossible task), and the sources/scripts for building the pre-built
libraries are also provided (http://sldev.free.fr/libraries/sources/ ).

Be warned however, that porting the viewer to *BSD would require C/C++
programming skills (i.e. beyond what is needed to simply compile the
viewer or its libraries), and that I won't be of help for this task
(no *BSD system here, and no time whatsoever to devote to such a port).

Not sure there is a recent enough port of CEF (*), indeed, but once you
got the CEF binaries, building Dullahan won't be much of an issue, using
my sources/script as a base.

(*) With a quick search on the web, I only found this:
https://github.com/prash-wghats/Brackets-CEF-for-FreeBSD/tree/master/CEF
but it's way too old (CEF 51, and currently using CEF 74).

> and voice support.

Voice support is largely hosed under Linux anyway (the v2.1 voice client, 
which is the last Linux version Vivox provided, still works for public
voice chat, but you cannot do voice with another resident not using
themselves that same old client).

However, for a vast majority of SLers (especially non native-English-
speaking residents, but also all genuine role-players), voice is not
even a useful feature of SL (never using it myself), so...

> Also, FreeBSD's OSS (open sound system) is not implemented in the viewer

Wrong !   The viewer got support for OpenAL, which itself supports the
OSS backend. FMOD sound would however be ruled out (not really an issue
either since OpenAL can do sound, including streaming).

Re: [opensource-dev] Error related to libndof when trying to compile SL on Ubuntu (attempt 2)

2020-02-06 Thread Alex 

Hi!

Regarding FreeBSD..

You will not get this to work on FreeBSD without an absolute buttload of 
work.. For starters, autobuild would not recognize FreeBSD as a valid 
platform, you would need to hack it to support FreeBSD (or write your 
own build system).


Many things would also be missing and would need implementing, like CEF 
and dullahan and voice support. Also, FreeBSD's OSS (open sound system) 
is not implemented in the viewer, so you'd probably have no sound. Then 
you would need to compile a metric tonne of dependent libraries for 
FreeBSD, or modify the build to use system wide libraries instead of 
trying to link against the packages ones that autobuild will try and 
download and link statically.


I wouldnt even go there... Just Dont. lol.

And yes, the linux build instructions are grossly out of date in LL's 
wiki. LL no longer provide a linux viewer or support it in any shape or 
form.
