[Flightgear-devel] No sound under Ubuntu 12.04
Hi all, I am trying to compile FG under Xubuntu 12.04 using Brisa's script (version 1.31). At first sight the compilation went fine, however sound is not working: when I run fgfs I get the following error and no sound: AL lib: oss.c:169: Could not open /dev/dsp: No such file or directory Error: Audio device not available, trying default AL lib: oss.c:169: Could not open /dev/dsp: No such file or directory Error: Default Audio device not available. (and indeed there is no /dev/dsp device on my machine). A closer look at the compilation log (http://www.mguillaud.net/fg/compilation_log_20120523.txt) reveals that PLIB fails to compile due to some incompatibility with the OSS interface (the compilation script does not stop, though). Then I tried to build OSG, Simgear and FGFS against the PLIB version from the Ubuntu repositories instead - same result. Compilation goes fine, but running fgfs with --show-sound-devices produces the same errors as above, and then: unknown provided by unknown No. Device What I find suspicious is that no sound devices at all are detected, although I believe I have ALSA and Pulseaudio properly installed (including -dev packages). Any clues about what is going on and how to further debug this ?

[Flightgear-devel] Hawaii regional textures merge request
Okay, given yesterday's discussion, I don't know if there is still need to discuss further or not or if this should be merged or not, but I'm putting this up now as I'll be travelling next week and won't have any decent internet connection to rebase my local branch properly, so anyone can have a look. https://www.gitorious.org/fg/fgdata/merge_requests/154 This has still issues (I couldn't find a decent GPL tundra texture to get the desired effect, so I had to do one myself, but it still has some tiling problems and too little variation, and of course the transition of lush tropical to dry volcanic shrub cover is somewhere between Oahu and Molokai with the line determined by visibility (i.e. it probes aircraft position at tile loading time, and the tile is of course at the view edge). Still, I think it makes the Hawaii experience much nicer.

Re: [Flightgear-devel] Random Buildings - memory consumption
Hi,
I don't have any clue of the opengl and simgear based stuff, so I looked only
at the struct Building and how to optimize that.
In the attachment you can find 3 structs representing the data.
The original is yours.
'small' is a very small optimization that doesn't require you to map floats to
discrete values. The flags variable holds bool pitched and the building type. I
assumed floors not to be bigger than 65k, so I reduced it to 16 bit ;).
In 'aggressive' I replaced the floats which I think doesn't require the full 4
byte precision of a float. However the mapping from float-int int-float can
take much time depending on the translation function you use. If normal float
division/multiplication is too slow, you could write some functions to directly
accessing the float (shifting the fraction depending on the exponent)
(http://en.wikipedia.org/wiki/Single_precision ).
However just ideas on that struct. Sizes in bytes:
original: 44
small: 36
aggressive: 28
Regards,
scosu

Hi All,
Emilian and Vivian have pointed out a problem with the random
buildings - they gobble memory. I'd like to get some advice on
whether there's any solution, and also to ask someone with more C++
knowledge than myself to take a look at the code and check I'm not
doing something stupid.
The specific problem scenario is starting a KLAX (Los Angeles) which
is in the middle of a massive urban area.
Using the default random building density, the tiles that are loaded
initially when sitting on the runway generates ~ 340k random
buildings. Each building consists of between 9 and 12 quads (we have a
basement at the bottom to handle slopes, 4 walls, and a roof which
may be pitched). In turn, each quad has 4 corners, each of which has
a position (vec3), a normal (vec3) and a texture coordinate (vec2).
So, the absolute minimum memory occupancy of the data for the random
buildings is 340k * 10 * 4 * 8 = 108MB. On top of that will be some
OSG overhead and the building texture itself.
Once you start flying more tiles are loaded (presumably well before
any old tiles are unloaded?) so memory occupancy rapidly increases.
Flying east from KLAX is particularly bad.
Using a higher building density makes the problem much worse, as you
need 4X the number of buildings to get double the linear density. I
ran out of memory on a 4GB system pretty quickly (and tile loading
takes an age - something I need to look at again).
So
- Does anyone have any bright ideas on what I can do to reduce the
base memory occupancy? One option might be to not generate the
basement if the terrain is level.
- Could a fresh pair of eyes take a look at the obj.cxx, mat.cxx and
SGBuildingBin.[ch]xx code to see if I've missed something obvious.
Thanks,
-Stuart

Hi Ignacio, My old .alsoftrc was forcing everything to be played through OSS (I guess that used to make sense back when OSS was the only reliable option, but now OSS seems to be broken). I simply deleted the .alsoftrc file from my home directory. Now OpenAL sees all the available options, and I get the following list when I run fgfs --show-sound-devices 0. PulseAudio Default 1.
