01:34.17 CIA-20 BRL-CAD: 03johnranderson * r30947 10/brlcad/trunk/ (6 files in 2 dirs):
01:34.17 CIA-20 BRL-CAD: Added support for a variable length byte buffer (bu_vlb). Similar to bu_vls,
01:34.17 CIA-20 BRL-CAD: but not string based (null byte is not special). Anticipated use in librtserver
01:34.17 CIA-20 BRL-CAD: which is scheduled to change its Java return to a simple byte array.

02:42.36 CIA-20 BRL-CAD: 03starseeker * r30948 10/brlcad/trunk/src/proc-db/tire.c: Add options to override the 'd' flag values, in order to have floating point dimensions as input.
02:53.11 starseeker_ weird
02:53.31 starseeker_ suddenly doesn't get raytraced output of tire, even though it was working before dinner...
02:53.55 starseeker_ wireframe's there...
02:54.28 starseeker_ decides sleep is in order first, and kicks off a couple fresh builds.

05:42.40 pacman87 hi yukonbob
05:57.34 yukonbob what's happening, pacman87 ?
05:57.48 pacman87 last week of school
05:57.55 pacman87 all the projects are due :(
05:58.17 pacman87 finals week is easy compared to this

06:22.15 yukonbob :P -- good luck w/ it all, pacman87
06:23.20 pacman87 thanks. i plan on cranking out some more code this weekend when it's all over and i finally have some time

09:20.58 BeerSerc_ hi there. sourceforge is down, whereelse can I get a copy of the amd64 linux binary or source?
09:32.54 kwizart BeerSerc_, which distrib ?
10:24.39 BeerSerc_ kwizart: gentoo
10:25.14 kwizart arf! at least i have a src.rpm where you might take the source from (with some patches)
10:25.41 kwizart http://rpms.kwizart.net/fedora/development/SRPMS/brlcad-7.12.2-1.fc9.kwizart.src.rpm
10:26.48 BeerSerc_ thank you, I'll try
10:26.57 *** join/#brlcad mafm (n=mafm@elnet-111.lip.pt)
10:27.05 mafm howdy
10:27.47 kwizart BeerSerc_, for the record, do you have a librt.so.1 in /lib64 on your system ?
10:28.56 mafm still with problems creating the package kwizart? :)
10:29.21 kwizart well, no the package works... but i guess there is still some minors things to fix
10:29.28 BeerSerc kwizart: Yes I have
10:29.53 kwizart at least I need to see how to deal with glibc librt.so.1 in linux system
10:30.19 kwizart and eventully split the package between differents composents...
10:30.25 kwizart components
10:31.20 kwizart for example, if some files might only be needed on server side for collaborative works... and others needed for workstation side
10:31.34 kwizart i don't know brlcad well enought to sort this for now
10:38.35 BeerSerc kwizart: I just noticed that there is an ebuild for 7.12 in gentoo's science overlay, so installing it should not be too difficult
10:39.34 kwizart BeerSerc, yep... i don't know how they deal with that problem thought...
10:39.50 kwizart maybe they still use rpathes
10:40.19 BeerSerc which problem is that exactly? I read something about glibc files, but in gentoos bugtracker, there are no bugs related to the 7.12 ebuild at all
10:40.40 kwizart that's not a problem specific with 7.12
10:41.34 kwizart i would like to see this ebuild...if there is some patches from their side
10:42.22 BeerSerc http://bugs.gentoo.org/attachment.cgi?id=149864
10:42.28 BeerSerc http://bugs.gentoo.org/show_bug.cgi?id=77197
10:47.14 BeerSerc ah i found a working sourceforge mirror... so I can use the tar.bz2 ting

10:51.33 kwizart ln -s librt.so.19.0.1 librtserver.so
10:57.04 kwizart they build tcl/tk internally ? strange for a gentoo ebuild...
11:28.04 *** join/#brlcad hippieindamakin8 (n=hippiein@210.212.55.3)
11:35.27 brlcad kwizart: bbiaw to help ..
11:39.51 brlcad kwizart: the ebuild doesn't need to use tcl/tk internally, but there is still an issue with itcl/itck from portage iirc (and compiling them out of sync makes the build very unhappy)
11:40.03 brlcad wanders off for a bit
11:40.08 kwizart ok
11:44.39 BeerSerc time for a total noobish question: How can I start brlcad? there is nothing looking like a main binary in /usr/brlcad/bin...
11:51.03 kwizart mged ?
11:52.05 BeerSerc ah OK. thx

12:24.17 louipc heck sourceforge is down?
12:24.24 alex_joni yup
12:24.49 louipc heh it always seems like it just when I need to use the damn site
12:25.20 alex_joni louipc: maybe it's just all the time, and you only notice it when you need it :))
12:25.29 louipc haha
12:26.07 alex_joni google gives 450.000 results for "sourceforge down"
12:26.26 louipc http://pastebin.ca/1002814
12:26.30 louipc anyways I'll stick that there
12:26.46 louipc don't know if that's been encountered yet or not

12:46.35 andrecastelo good morning everyone
12:50.42 clock_ alex_joni: now you have to read through all of them, otherwise people tell you STFW or UTFG
12:51.04 alex_joni clock_: sorry?
12:51.33 clock_ alex_joni: sarcastic about the STFW acronym
12:51.52 alex_joni did I say that?
12:54.23 alex_joni clock_: I usually try to keep it more polite (like GIYF :)
12:57.57 mafm hi andrecastelo
12:58.43 louipc hah I don't know what any of those mean
13:02.54 clock_ AATNKWIM
13:03.04 clock_ An Acronym That Noone Knows What It Means
13:03.51 mafm louipc: that's funny, because in that case is perfectly applicable to you :)
13:05.19 CIA-20 BRL-CAD: 03starseeker * r30949 10/brlcad/trunk/src/proc-db/tire.c: Whoopsie, tire thickness needs dztred to be calculated first.
13:19.45 CIA-20 BRL-CAD: 03starseeker * r30950 10/brlcad/trunk/src/proc-db/ (tire.1 tire.c): Add docs for options to specify just width, ratio, or wheel diameter.

14:12.55 brlcad d_rossberg: how critical are those tcl changes? i fear they'll just get clobbered the next time tcl is updated
14:13.02 brlcad (e.g. tcl 8.5.2 is out)
14:13.36 brlcad and/or more importantly is there a way to work-around it that doesn't require a mod to tcl
14:19.03 d_rossberg brlcad: don't care about this change
14:19.31 d_rossberg if you have a new tcl version put it into the repository
14:19.53 brlcad i don't plan to anytime soon, there's no pressing need
14:20.21 d_rossberg if it's a problem for me i'll look after after it
14:20.22 brlcad but just saying that someone might replace it on a whim just for the sake of upgrading (erik has that tendancy) .. didn't know if that'll break the cmake build or something
14:20.29 brlcad okay
14:21.37 d_rossberg the whole tcl thing is "experimental" for me :)
14:22.23 brlcad heh
14:23.55 brlcad hrm, anyone recall the name of the apache load testing tool? stfw isn't helping much

22:59.46 starseeker_ Ah HAH - http://pastebin.bzflag.bz/m532f157a
23:00.01 starseeker_ or more specifically, libtcl8.5.so => /usr/brlcad/lib/libtcl8.5.so (0xb7799000)
23:00.15 brlcad bingo
23:00.16 starseeker_ bad BRL-CAD, no system libtcl for you...
23:00.33 starseeker_ now, where are you going wrong...
23:00.41 brlcad didn't you say it was an --enable-all ?
23:00.45 starseeker_ yep
23:00.54 brlcad does config.log confirm that?
23:01.12 starseeker_ <PROTECTED>
23:01.14 brlcad (header at the beginning and summary at the end)
23:01.44 brlcad oh, wait
23:01.52 brlcad you did an ldd on an uninstalled .so
23:02.00 brlcad that's not right
23:02.09 brlcad you can't do that (and expect correct answers)
23:02.13 starseeker_ grr
23:02.24 brlcad that's why the binaries run through scripts
23:02.32 brlcad those scripts set up the ld library paths
23:02.46 brlcad iff you want to run the binary prior to install
23:03.07 brlcad if you want to know the true ldd before install, you have to add it to the script
23:03.21 brlcad e.g. to src/mged/mged near the bottom before the exec
23:04.18 starseeker_ but the compile doesn't get that far...
23:04.44 brlcad ah, right failing at comb?
23:04.49 starseeker_ yep
23:04.57 brlcad then it just amounts to what's on the compile line
23:05.05 brlcad add that flag I mentioned to turn on verbose
23:05.12 brlcad get the real gcc line
23:05.16 starseeker_ --debug ?
23:05.18 starseeker_ one sec...
23:05.29 brlcad or copy/paste the libtool line and remove the silent option
23:05.38 starseeker_ did that, actually...
23:05.48 starseeker_ pastebin coming up...
23:06.11 brlcad pastebin's getting a fair bit of spam .. someone(tm) needs to turn on recaptcha for it
23:06.19 starseeker_ http://pastebin.bzflag.bz/m61107cd0
23:06.37 starseeker_ are we spamming the bzflag irc channel by using it?
23:06.53 starseeker_ doubts most bzflag hackers care about brlcad...
23:07.36 brlcad presumably there is a libtcl8.5.so in /home/cyapp/cadtoplevel/brlcad/brlcad-build/src/other/tcl/unix ?
23:07.48 brlcad no, it's fine to use
23:08.00 starseeker_ yes, it's there
23:08.02 brlcad I could just as easily make that pastebin.brlcad.org
23:08.10 brlcad it's not a symlink to nothing?
23:08.16 brlcad it's an actual lib
23:08.27 starseeker_ yes, seems to be
23:08.40 brlcad then the next step is to check the lib for that symbol using nm
23:09.16 starseeker_ goes to find out what nm is...
23:09.19 brlcad if it's in there, then you gotta take gcc/ld into a lower level debug mode; if it's not in there, you have to look into tcl's build to find out if it's supposed to be
23:10.41 yukonbob waves in
23:10.47 starseeker_ I'm looking for libtcl with nm in librt.so?
23:11.27 *** join/#brlcad cad64 (n=80731b0a@bz.bzflag.bz)
23:11.33 brlcad nope
23:11.38 starseeker_ Is the presence of -ltcl8.5 harmless?
23:11.52 brlcad you're looking at the symbols in libtcl8.5.so
23:11.56 starseeker_ ah
23:12.10 brlcad is the symbol it's failing on actually in that library
23:12.50 starseeker_ 00023590 t TclReFree
23:13.41 brlcad out of curiostiy, if you move/delete /usr/brlcad/* does it still fail?
23:14.07 starseeker_ yep
23:15.30 *** join/#brlcad cad64 (n=80731b0a@bz.bzflag.bz)
23:44.52 starseeker_ is out of his depth here...
