02:26.21IriX64dudes...
02:26.53IriX64the & part of that check does nothing, it will always result true dont you think?
02:27.15IriX64the null part is covered by if!_ptr
02:27.57Twingyno
02:27.58IriX64i see what its supposed to do
02:28.15Twingyit's checking the valid bits
02:28.21Twingypointers have alignment
02:28.37Twingyit's checking that you don't have a misaligned pointer
02:28.49IriX64but some are pointers to structs twingy its not always a long
02:28.52Twingyi.e bad mojo stored in the last 3 bites for a 32-bit machine
02:29.02Twingyforget about the long
02:29.08Twingyit's cast to a long to do an and operation
02:29.17Twingyit could just as well be an int
02:29.23Twingyor a ptr_t
02:29.26IriX64i get you
02:29.41Maloeranintptr_t or ptrdiff_t would be the appropriate portable integer data types to hold a pointer
02:30.17Twingynot a good check to run if you are storing extra bits in your pointers
02:30.22Twingyas ray-tracing engines tend to do
02:30.32IriX64true who does that ? :)
02:30.36Twingyeveryone
02:30.48IriX64heh mea culpa
02:31.17IriX64putting a return on that macro for saome reason fixes the terra.g crashing mged problem tho , tested it works.
02:31.22MaloeranI have a "flags" int32_t in both nodes and sectors, I have bytes to waste to reach proper alignment for structs
02:32.06Twingyeveryone-Maloeran
02:32.10Twingy:)
02:32.15IriX64heh so i see
02:32.45TwingyMaloeran, when do you leave?
02:32.57MaloeranPlane is tomorrow at 12h
02:33.00Twingyah
02:33.07Twingyif it left later I'd take you flying
02:33.15Twingybut I think it's raining tomorrow
02:33.24MaloeranDo you think I can call a cab here to get me to the airport?
02:33.35Twingythere are shuttles that do that
02:33.41TwingyI think it's called "Rapid Rover"
02:33.43MaloeranIt's rather far, the taxi from the airport costs 95USD
02:33.54Twingythere are speacial vans that pick people up and take them to the airport
02:34.01MaloeranHum.
02:34.11Twingythey usually run around and pick up 3 or 4 people and hit the airport
02:34.15MaloeranShould I ask the front desk for information about these things?
02:34.17Twingyin the same general area
02:34.22Twingycosts $40 or $50
02:34.32Twingymaybe
02:34.37Twingygoogle would probly help
02:34.43Twingyor the baltimore airport website
02:34.53TwingyI know at philadelphia airport
02:34.59Twingyrapid rover will show up in a van for like $50
02:35.12MaloeranI see, neat
02:35.37MaloeranA taxi could be fine too, assuming he really wants to go that far
02:35.54Twingyor grab a train to the marc station
02:35.56Twingyerr taxi
02:35.59Twingyto marc train
02:36.05MaloeranRapid Rover seems specific to PHL airport
02:36.09Twingyk
02:36.22TwingyBWI might have it's own version of that
02:36.30MaloeranLooking
02:37.20MaloeranBWI shuttle doesn't appear to go as far as Belcamp. Oh well, a taxi it is
02:37.34Twingywhat about marc train?
02:38.04Twingythen again, marc train would be slower
02:38.07Twingybut alot cheaper
02:38.09MaloeranI'm unsure about experimenting with new means of transportation in a new area when on a tight schedule ( a train to catch )
02:38.13Twingyk
02:38.14Maloerana plane to catch, rather
02:38.30TwingyI'll let you sleep in one of my tool sheds if you miss the plane
02:38.36Twingyif you're real nice I'll let you stay in the garage
02:38.55brlcadyeah, should be 40-50
02:39.31TwingyI'm so proud of myself
02:39.39brlcada vanilla taxi would be bad - have to get an airport shuttle
02:39.40TwingyI wrote some opengl code that displayed lines today
02:39.48brlcadheh
02:40.00brlcadand I made an excellent white russian
02:40.15TwingyI'm working on my last diet pepsi
02:40.52Maloeranbrlcad, a standard taxi wouldn't be appropriate? Hrmph.
02:41.10MaloeranI guess I'll just ask the front desk tomorrow to pick whatever works
02:43.34brlcadMaloeran: yeah, concierge should have connections to the airport shuttles, though you usually need a couple hours advance notice
02:43.43MaloeranI may get a driving license eventually, but I won't get a car anyhow... unless I move to ~Belcamp some day
02:43.57Twingyconcierge, that's a fancy words
02:44.14TwingyMaloeran, a compressed air car
02:44.16MaloeranThanks brlcad, I'll try to wake up early enough
02:44.21TwingyI am going to build a compressed air bike
02:44.43Twingyas long as the bike doesn't fall over it won't explode
02:44.51MaloeranThat air tank is going to be heavy.  A muscle powered bicycle performs remarkably well too
02:45.06TwingyI'm more interested in doing something new
02:45.34MaloeranA wind powered car?
02:45.41brlcadif you end up having to take a regular taxi, it will be more expensive (not that you really need to care a "whole lot", it's a business expense)
02:48.20MaloeranAh right, I need to remember to collect receipts too
02:49.43brlcadyep
02:53.40Twingyreceipts can be burnt in my steam engine
02:53.45Twingyyou should save those
02:54.46Twingyeach one is worth a femtocent
02:57.45TwingyNot the mama!
02:57.53Twingymomma

20:58.25poolioLooks like blrcad on windows =(
21:08.55IriX64that one is brlcad "on" windows
21:09.01IriX64same url
21:11.25IriX6432768 global photons, 1024 irradiance rays... how long will i be waiting?
21:21.04poolioI have no clue what you're talking about, but I'm going to go with a magnitude of hours?
23:33.51pooliobrlcad: I'm having trouble compiling brlcad. misc/Makefile.in is not being created
23:37.21IriX64poolio, good guess , it's still not ready
23:38.08IriX64poolio starting from ./autogen.sh ?
23:38.14IriX64makes it here
23:38.50brlcadpoolio: cvs head is a bit unstable at the moment
23:39.00brlcadwe're cleaning some things up for a release
23:39.33brlcadthough misc/Makefile.in does indeed imply that something went wrong during autogen.sh
23:39.46brlcadrun ./autogen.sh --verbose
23:40.07IriX64brlcad: are you saying the source(7.8.4) tarball is at the moment more stable than cvs head?
23:42.11brlcaddepends on what you're doing, but from a simple compilation standpoint -- perhaps
23:42.52brlcadhead is allowed to change you know, usually changes daily
23:43.15brlcadthere will be a STABLE branch created after this next release so HEAD can be more fluid too
23:43.46pooliobrlcad: I did, nothing wrong there
23:47.05brlcadsomehow I fail to believe that :)
23:47.13brlcadif there really is no .in file
23:47.36brlcadthat means something in automake failed to produce the file
23:48.15brlcads/in automake failed/caused automake to fail/
23:49.38poolioWell there are warnings from lib3ds, but no error messages or things that would indicate a failure of creation
23:50.06brlcadcan you pastebin the output?
23:50.39poolioYeah, hold on.
23:52.22pooliobrlcad: aha! My eyes decieve me. src/external/Makefile.am:3: BUILD_CUBIT does not appear in AM_CONDITIONAL
23:52.39brlcadaha
23:53.01brlcadyes, just a recent mod -- there's an AM_CONDITIONAL missing in configure.ac
23:54.50pooliobrlcad: what's the test supposed to be for BUILD_CUBIT?
23:55.41brlcadnear the bottom.. there's a bunch of AM_CONDITIONALS
23:55.50brlcadcan just add a line for BUILD_CUBIT that is false
23:56.07poolioah alright
