00:11.36 starseeker ``Erik: main advantage would be one build system for Windoze and other platforms
00:11.56 starseeker ``Erik: yeah, that's annoying
00:12.11 starseeker remember some investigation into that practice a while back, come to think of it...
00:13.35 ``Erik well
00:13.40 ``Erik there ws a story about a legal dealie
00:14.01 ``Erik and what I'm hearing NOW, instead of the entire commercial blasting, it blasts for the very first bit, then quickly backs off
00:14.16 ``Erik at first, I thought someone was at a mixing board and was just slow at adjusting it down
00:14.25 ``Erik but it's the same curve in the same commercial several times
00:15.34 ``Erik only a few commercials are doing it :/ like the comcast commercial does it really bad

00:21.48 ``Erik hey, you can't make an omelet without subjecting a few eggs to fission
00:22.47 starseeker that'd make an awesome tshirt :-)
00:23.16 Ralith ``Erik: someone ported clisp to one of those nokia platforms, iirc.
00:23.28 ``Erik neat
00:23.32 Ralith and I think someone at least *tried* to get SBCL on ARM, may want to see where they left off.
00:25.42 ``Erik nope, clisp asploded on me
00:25.53 ``Erik actually
00:25.59 ``Erik ffcall asploded
00:28.37 Ralith I think there's a patched version?
00:28.45 Ralith I remember that being mentioned on the nokia thread
00:35.58 ``Erik *shrug* ain't the purpose of the machine, just figured it'd be amusing to try :)

03:19.54 gbttun hi, i'd like to know if i could get help with BRL-CAD installation here
03:26.18 brlcad ~ask
03:26.18 ibot Questions in the channel should be specific, informative, complete, concise, and on-topic. Don't ask if you can ask a question first. Don't ask if a person is there; just ask what you intended to ask them. Better questions more frequently yield better answers. We are all here voluntarily or against our will.
03:26.27 brlcad sure, usually
03:35.45 gbttun i've downloaded the brl tarball from sourceforge and unpacked it in /usr/brlcad. i've read the INSTALL file and attempted to follow the instructions: $sh autogen.sh
03:36.05 gbttun but the shell responds with 'can't open autogen.sh'
03:36.19 gbttun what step am i missing?
03:37.51 louipc try `./autogen.sh` ?
03:38.40 gbttun it can't find that file. cwd is /usr/brlcad, is it in another directory?
03:39.07 louipc oh what do you have in /usr/brlcad?
03:39.44 gbttun bin, include, lib, man, rel-7.10.4, share, stable
03:39.57 louipc oh you downloaded a pre built package
03:40.15 louipc you can try to run /usr/brlcad/bin/mged
03:40.52 louipc might have to add /usr/brlcad/lib to your library path
03:41.04 gbttun how do i do that?
03:41.41 louipc you would add the path to /etc/ld.so.conf and run ldconfig
03:42.12 louipc you're using linux yeah?
03:42.17 ``Erik which brl tarball did you download?
03:42.19 gbttun yes. ubuntu
03:42.23 louipc ok
03:42.30 ``Erik you seem to be mixing the instructions for source and binary...
03:43.01 gbttun brlcad_7.10.4_ia32.tar.bz2
03:44.20 ``Erik could you run "ldd /usr/brlcad/bin/rt" and paste the results to someplace like http://paste.lisp.org/ ?
03:45.41 ``Erik (and setting the LD_LIBRARY_PATH variable is a simpler and root-less alternative to updating the ld cache, the performance difference is neglegible these days)
03:49.08 gbttun http://paste.lisp.org/display/96078
03:49.38 ``Erik you're missing the stdc++ libraries
03:50.05 ``Erik in your ubuntu installer thingymajigger should be something that says "C++ runtime libraries" or "stdc++" or something
03:51.20 gbttun libstdc++ ?
03:51.33 ``Erik that sounds up the alley, yeah
03:52.04 ``Erik <-- not a linux guy, has never used ubuntu, .. doesn't know those details :/ mebbe loui knows? *shrug* :)
03:52.45 gbttun the description is 'the GNU Standard C++ LIbrary v3 (documentation files)'
03:53.20 louipc well, LD_LIBRARY_PATH is only supposed to be a temporary thing
03:53.23 ``Erik hm, ya want the libraries themselves, not the docs for them... does that mean with the docs, or just the docs?
03:54.06 gbttun it's just the docs :/
03:54.50 gbttun i'll look online, i don't think the packet manager has the stdc++ lib (unless it's in a repository that I haven't added)
03:55.02 ``Erik it should be part of the base system
03:55.12 ``Erik do you have any libstdc++* files in /lib or /usr/lib ?
03:55.17 louipc maybe that build is using an old version
03:55.47 louipc if you don't have any qualms against building from source I'd recommend it
03:55.49 ``Erik given that it's a very old version, I'd imagine so :D
03:56.27 gbttun when you say an old version, are you referring to brlcad or to the stdc++ lib?
03:56.36 ``Erik BRL-CAD
03:56.38 louipc well, I do still have /usr/lib/libstdc++.so.5 on my system
03:56.41 louipc :P
03:57.48 gbttun in /usr/lib, i have a libstdc++.so.6
03:57.56 ``Erik my old bsd clunk has 4, 5 and 6... my mac only has 6
03:58.58 louipc yeah looks like only 6 is available on ubuntu
03:59.26 ``Erik ok, then ya have a choice between two things, gbttun... A) build it from source and enjoy all the bug fixes and new features, or B) link a libstdc++.so.5 to your libstdc++.so.6, sacrifice a chicken, hope and pray that it works and just suffer the bugs and explosions that occur... :D
04:00.10 gbttun well, when you put it that way . . . haha
04:00.11 louipc C) install libstdc++ 5
04:00.21 louipc i'd choose A
04:01.01 gbttun alright, i'll try from source. never done it before. the documentation is in the brlcad lib, right?
04:01.24 louipc it's in the tarball
04:01.34 louipc and maybe the wiki can help as well
04:01.53 gbttun alright
04:02.29 louipc if you download the source via tarball you shouldn't need to run autogen.sh
04:02.36 louipc just ./configure, make, make install
04:04.03 ``Erik I'm guessing that ubuntu splits the runtime libraries and headers into seperate packages
04:04.33 ``Erik so'll have to, say, install libXi-dev in addition to having libXi ...
04:04.39 louipc oh yeah.. forgot about that
04:04.54 louipc you need to install everything-dev
04:05.00 louipc bahhah
04:06.04 ``Erik after running the configure script, READ that block at the end to see if it's gonna do what you want... mebbe put that on that paste site so louipc can tell ya if you missed anything... :D
04:08.58 ``Erik I... just figured out how the ancient egyptions were able to build such precise structures without modern surveying tools... I understand it now... they used cats. cats find the exact middle. every time.
04:10.55 louipc wow I never knew they could do that
04:11.20 louipc what's their accuracy?
04:12.17 ``Erik not sure, my other tools aren't highly accurate themselves
04:12.30 louipc oh hah
04:12.51 louipc I figure they were able to do it via experienced craftsmanship
04:13.23 louipc a good machinist can judge a size within .005 of an inch using just a steel rule
04:13.31 ``Erik well, they had, y'know, knotted ropes and stuff, but those were probably just for crud measurements when they didnt' have time for a cat to decide to sleep
04:13.43 louipc haha yea
04:14.05 ``Erik yeahhhhhh, I don't have a good machinist grade rule, even my calipers are crummy plastic things
04:14.10 ``Erik and no micrometer
04:14.59 ``Erik had to mill an aluminum cube to like 1" on each edge to within a pretty insane tolerance, something up the alley of that .005 or so... good fun
04:15.19 louipc haha that's a wide tolerance
04:15.51 ``Erik it was a highschool class, using some heavy duty gear, but it'd been abused by a lot of highschool students... don't remember the exact #'s
04:15.56 louipc but it's good fun for sure
04:16.00 ``Erik that was, uh, a long long... long... long time ago
04:16.28 ``Erik y'know, with the oxes pulling the drive spindle geared to the mill head, etc... :D
04:16.35 ``Erik oxen, rather
04:16.48 louipc hah forget that, you're supposed to file it
04:16.58 ``Erik heh
04:17.10 ``Erik early 90's, anyways *shrug* :D
04:17.17 louipc file it down to the req'd shape and size
04:17.19 louipc heheheh
04:17.39 ``Erik did a lot of filing in that class, mostly de-burring the sheet metal we'd snipped or clipped in the brake
04:17.48 ``Erik or fine work after welding
04:20.03 louipc hmm now I have an idea for text winter
04:20.06 louipc snow pyramid
04:21.36 ``Erik heh, make the bricks like ya do for igloos?
04:22.00 louipc haha nice!
04:22.04 ``Erik the nifty part would be the tunnel down to the snow sarcophogus with the smummy in it
04:22.28 ``Erik which'd be a partially melted but preserved snowman, right? :D
04:22.51 louipc of course
04:28.42 gbttun ok, i've run configure. http://paste.lisp.org/display/96078#1
04:29.12 ``Erik missing X headers, you won't get a gui with that
04:30.27 ``Erik that'd be like, uh, Xlib-dev libXi-dev ...
04:31.11 louipc gbttun: install tcl too
04:31.33 ``Erik http://brlcad.org/wiki/Compiling
04:33.17 louipc perfect
04:33.55 gbttun oops, supposed to install the dependencies/tools first, huh. i'll have to recompile afterwards?
04:34.04 ``Erik (why are both 8.5 and 8.4 listed?)
04:34.18 ``Erik you'll have to run configure again, you haven't compiled yet
04:48.23 gbttun http://paste.lisp.org/display/96078#2
04:48.37 gbttun i installed the dev libraries, but still no GUI?
04:51.25 ``Erik ya need the "X11 support" to say yes
04:55.13 *** join/#brlcad gbttun (~gbttun@c-24-6-17-7.hsd1.ca.comcast.net)
04:59.04 louipc gbttun: you should install what the wiki page mentions
04:59.11 louipc gbttun: http://brlcad.org/wiki/Compiling
04:59.42 louipc as well as the non-dev counterparts
05:00.08 louipc I think it would be safe to omit tcl8.4 and tk8.4 though
05:02.03 gbttun i'll install the non-dev counterparts, i've installed all pkgs mentioned in the wiki
05:02.22 louipc cool
05:12.17 gbttun checked all the non-dev counterparts, and they're already installed
05:13.33 louipc hmmm
05:15.56 louipc must be missing something though
05:19.13 gbttun many of the x11 packages have different numbered pkgs-dev/doc/etc
05:19.21 gbttun a restart wouldn't help, i suppose
05:19.44 louipc I wouldn't think so
05:19.52 louipc it's not windows hehehe
05:19.58 gbttun heh
05:21.08 louipc if you posted the full configuration log, that might help to figure out what's missing
05:29.06 gbttun have any target areas? config log is too big to paste Oo
05:30.46 louipc anything that says 'no' ahha

16:41.15 starseeker brlcad: oh, is that cmake branch OK?
16:41.27 starseeker doesn't want to add clutter...
16:42.18 brlcad it's only adding to clutter if you don't follow through with it or use it down the road
16:42.41 starseeker nods

16:43.13 starseeker or if ``Erik decides it needs to die O.o

16:58.13 CIA-85 BRL-CAD: Added a -o option to mged for starting the new gui. This will eventually be used
16:58.13 CIA-85 BRL-CAD: to fire up the old gui. Cleaned up the possible bad behavior with the -a option.
16:58.13 CIA-85 BRL-CAD: For example, if -a is specified apart from classic mode it brings up the gui
16:58.13 CIA-85 BRL-CAD: with an extra display. Also modified the archer script to work from mged.
16:58.30 starseeker brlcad: heh. That was about ``Erik's response
17:13.39 CIA-85 BRL-CAD: 03bob1961 * r37935 10/brlcad/trunk/src/mged/mged.c: Fixed a typo.

17:30.20 ``Erik brlcad: know when you're back in? glenn was looking for you to help him, he wants to make a .pkg or something

17:38.00 brlcad ``Erik: what's up with all the proxy servers on crit?
17:38.50 ``Erik it forks children out to handle connections, just like apache...
17:39.53 brlcad I mean are you actually proxying something?
17:39.53 ``Erik yeah
17:39.53 brlcad or is the server just there running
17:39.53 ``Erik it only listens localhost, ssh -L ftw
17:41.39 ``Erik oh my, migration time O.o
17:42.47 brlcad yeah, working on verifies, backup, maybe get apache migrated today if lucky
17:43.35 ``Erik apache won't start until it thinks it can resolve all the hosts to itself, iirc
17:45.20 ``Erik dunno if ya wanna do 'one big whump' and just lose service for a bit while that happens, or do some more slow migration (make irssi a shell script that says "go use the other machine", mebbe ssh tunnel the mysql port, etc)
18:01.35 brlcad the hosts can be migrated one by one
