 Hello,
 this is now going to be the third release in a row that relies on PLIB
 CVS, I find this is a bit unsatisfactory. On the other side people are
 waiting endlessly to get patches incorporated into PLIB.
 
 I herewith propose to put a copy of PLIB into the SimGear tree after
 the release is out, to rip those pieces off that FlightGear doesn't
 use (think of the audio stuff) and to maintain the rest inside Simgear.
 The few patches that the current PLIB CVS tree actually sees should be
 easily tracked and incorporated into Simgear/PLIB if required.

Wow, I've been so out of the loop up to a month and a half ago that
 had no idea the releases were being built on PLIB CVS.  But
yesterday I came across a post I made in late February asking
whether Tiago Gusmão's texture compression stuff had made it into
plib or not, and his replying that after over a month he was still
having trouble getting folks on the plib development list to reply.

How much extra work would this mean *after* putting it into SimGear?
Does plib have a high patch submission rate, thus requiring that
someone would have to duplicate the efforts of whoever evaluates
and commits patches for plib?

I've been building CVS with plib-1.8.4 (the last release) for ages with no 
particular problems, so I'm not sure it's true to say that we _rely_ on PLIB 
CVS.  This is not to detract completely from your point though...

That seems to be true.  I'm personally using Tiago's texture compression patch 
with 1.8.4 and it is the sort of thing that would have been applied almost 
immediately were it part of simgear, say.

We should also bear in mind the possibility that PLIB might not be the most 
suitable platform for fgfs in the future and that migration to OSG would be 
an option.  However, I'm not a coder and other than having played about with 
some fairly inspiring (visually) OSG applications, I have no really valid 
opinion on that matter; that would almost certainly be post-1.0 anyway I 
would imagine?

Cheers,

AJ

I think that this provides a sensible migration route to OSG, if that is the
way we are going, otherwise it seems a good proposal in its own right. Apart
from the number of updates required (small) I can't see a downside.

 plib-cvs that we could benefit from, then we should encourage those guys 
 to do another release.

Several patches and improvements went in since the last release of PLIB
happened and nobody managed to convince Steve to do a new release over
the last year. You probably don't notice the problems with 1.8.4
because you run Linux, people using other platforms run into
difficulties with 1.8.4. On the other hand there are small but known
bugs in the build system of PLIB CVS and nobody cares over months

True,
I have most of that parts of ssg that are required by flightgear simgear 
reimplemented using osg nodes below.
That is not yet ready for use, but that might be a useful way to go.
