21:47.25whitehawkhi
21:48.01docelichi
21:48.12whitehawkI just found brlca, tried to compile it..
21:48.27whitehawkIn file included from jove_buf.c:64:
21:48.28whitehawk./jove.h:256: warning: built-in function 'exp' declared as non-function
21:48.28whitehawk./jove.h:477: error: conflicting types for 'malloc'
21:48.30whitehawkgot this..
21:49.19whitehawkand then after some all-recursive notes compiling failed
21:49.46docelicok the first thing is a warning so it doesn't matter
21:50.12whitehawkyes I know
21:50.34docelicthe malloc thing is an error. You need to look up how is malloc declaration line in jove.h, line 477, different from malloc definition in your /usr/include/malloc.h
21:51.48docelic(Not that I use brlcad, but this is generic troubleshooting method).
21:52.09whitehawkthis is in jove.h: *malloc(),
21:52.52docelicwhat platform and compiler ?
21:54.27whitehawklinux  gcc-3.4.5, glibc-2.3.6-r2, 2.6.14-ck6-2 x86_64
21:54.35docelicIf I got the context right, try replacing  *malloc()  to be  *malloc(size_t)
21:56.07whitehawknpoe
21:56.33whitehawknope
21:56.38doceliccan you give me 2 lines before and after 477 ?

21:57.26whitehawk<PROTECTED>
21:57.26whitehawk<PROTECTED>
21:57.26whitehawk<PROTECTED>
21:57.43docelicah, yeah, that wasn't it then..
21:58.19docelicdoes it tell you where is the previous definition of malloc that conflicts ?
22:08.28brlcadhowdy
22:08.38brlcadwhitehawk: that was fixed in the latest cvs
22:10.42brlcadthe fix is easy, just remove the malloc line there
22:11.01brlcador disable jove, you don't need it if you've never used it
22:12.02docelicah, hi brlcad :)
22:13.49brlcaddocelic: you had the right fix, but it needed to return void* too ;)
22:14.12brlcadi believe the old jove code is using the old char* return format
22:17.52CIA-5BRL-CAD: 03brlcad * 10brlcad/TODO: geometry viewing commands/visualizations of exploded levels. mulled over this years ago, but davisson revitalized some interest/discussion.
22:21.07whitehawkbrlcad what is jove? I'm totally new to brl cad
22:21.30brlcadit's a streamlined version of emacs, for back in the day when not every machine had an editor installed
22:21.39brlcad"jonathan's own version of emacs"
22:22.10docelicYeah. It's also available as a standalone package in your distribution, so you can disable it
22:22.48whitehawkwhat is the prodesktop plugin?
22:23.08brlcadit's in the src/other directory, which is filled with optional stuff that is just provided for provenience
22:23.40brlcadi presume you mean the protoolkit pro-engineer plugin
22:23.49brlcadit's a plugin for pro/e
22:24.06brlcadlets you export directly to brl-cad format from inside of pro-engineer
22:24.53whitehawkcan I import from proe inside of brlcad?
22:25.56brlcadproe is a closed proprietary format
22:26.20brlcadwe'd have to pay 10k seat or somesuch and only distribute binaries
22:26.26brlcadnot very practical
22:26.46brlcadthere are a variety of formats that you can export from within proe that brl-cad will read
22:26.58brlcadlike stl, vrml, iges, ..
22:27.30whitehawkiges as I remember we used that in cosmos geostar

22:33.02brlcadhowdy fotter
22:33.12fotterhi there
22:33.55fotteri wonder if anyone can help (i'm also new to irc as well...) as i'm having a problem with rt...
22:34.19brlcadno problem, someone usually can ;)
22:35.11fottersorry to dive straight in :-)
22:35.26brlcadthat's the irc way ;)
22:35.50fotteri'm in the raytrace control panel, and when i hit 'fbclear' i get an error:
22:35.56brlcadjust often won't get an immediate answer, have to hang around until someone is available to respond
22:36.23fotterRt Error: couldn't execute "fbclear": invalid argument
22:36.39brlcadhmm
22:36.40fotterah ok, no probs, just happy whenever!
22:36.50fottergoogled etc, but couldn't find anything
22:37.09brlcad1) what version are you running and 2) did you set your path?
22:37.33fotter2) yes, my execute path includes /usr/brlcad/bin
22:38.07brlcadls -la /usr/brlcad/bin/fbclear
22:38.32fotter-rwxr-xr-x  1 root root 14973 2006-02-15 17:48 /usr/brlcad/bin/fbclear
22:38.43brlcadlooks good
22:38.50brlcad/usr/brlcad/bin/fbclear -F/dev/X
22:38.57brlcadshould flash a window
22:39.02fotterit did
22:39.34brlcadso then.. 1)?
22:39.45fotter1) i downloaded the latest version today and compiled, 7.6.6
22:40.45fotteron ubuntu 5.10
22:41.01brlcaddid you raytrace first?
22:41.04fotteryes
22:41.09fotteri have a nice sphere :-)
22:41.18brlcadtype fbclear into the command window
22:42.07fotterError: invalid command name "fbclear"
22:43.29brlcadhmm
22:43.50fotterother commands work from the command window - i created the sphere from there, and typing 'rt' in the command window also works
22:43.50brlcader, do_fbclear id_0
22:44.13brlcadsame error?
22:44.35fotterah right, yes, it gives Rt Error: couldn't execute "fbclear": invalid argument
22:44.46brlcadmkay
22:44.50brlcadputs $env(PATH)
22:46.10brlcad(in the command window)
22:47.19fotterError: can't read "env(PATH)": no such variable
22:47.56brlcadaha
22:48.35fotterTcl is something i know nothing about - shed some light please!
22:48.37brlcadset env(PATH) /usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/brlcad/bin
22:48.48brlcadtry that, then click fbclear again
22:49.40fotterthank you!!
22:49.52brlcadwell, that's only a half-fix then :)
22:49.57brlcadthat fixed it for this run of mged
22:50.10brlcadthe path isn't getting set correctly
22:50.23brlcadin the tcl interpreter
22:50.50brlcadwhich is a relatively recent change .. ubuntu seems to be the one that hits this problem
22:50.51fotterah ok cool. understood.
22:51.18brlcadif you want to change sources so that it works, since you compiled ..
22:51.25fotterno probs
22:51.29brlcadyou can edit src/mged/setup.c and search for
22:51.38brlcadHAVE_GETENV
22:52.04fotteram there
22:52.05brlcadthere's a line a few lines after with a "{", make that "if (0) {" and recompile and you should be golden
22:52.27fotterso replace binpath with 0
22:52.35brlcadno
22:52.46fotterright, ok. in wrong place maybe
22:52.51brlcadup a few more lines

22:54.25brlcadchange to be: if (0) {
22:54.31fotterright got you
22:54.34brlcadbasically disabling that section
22:55.12brlcadthat's a convenience for the plethora that don't seem to know how to set their path
22:55.35brlcadyet there's some peculiar tcl book keeping that isn't getting updated correctly
22:56.29brlcaddid you get a message when you run mged saying "unable to modify PATH" by chance?
22:57.01fotterbefore correcting the error? haven't recompiled yet, so will check
22:57.37fotterno errors written to the terminal, just the 'Initializing and backgrounding, please wait...Done'
22:57.49fotterand then up pops mged
22:57.56brlcadmkay
23:02.28fotterif there are any other checks/help i can give i'm more than happy... just finishing compiling the new mged :-)
23:02.52fotterso probably not the best time for help if i now have a working version though...
23:03.30brlcadoh, there is lots, I'd love to trace down why PATH doesn't get set ;)
23:04.05brlcadmake sure that works first, though :)
23:06.49``ErikO.o
23:06.50fotterwill do :-) just typed 'make install', although i guess i could have just copied across the mged binary?
23:07.03fotterbut anyway, it works perfectly. thank you!
23:07.11brlcadgood to know
23:07.15brlcadcare to try one more edit?
23:07.21fotterno probs
23:07.35brlcadchange that same line to if (1) {
23:08.10brlcadand add this right before the "#  ifdef HAVE_PUTENV" line below

23:08.35brlcad<PROTECTED>
23:08.53brlcadthose three lines right before the HAVE_PUTENV line
23:09.15brlcadthen if you compile and make install, it should report two lines when you run mged.. and hopefully still work
23:09.17fotterok they're in
23:10.12fotterjust waiting for it to compile
23:16.00fotterOLD_PATH = /usr/local/bin:/usr/local/sbin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/bin/X11:/usr/games:/usr/brlcad/bin
23:16.00fotterNEW_PATH = PATH=/usr/local/bin:/usr/local/sbin:/sbin:/usr/sbin:/bin:/usr/bin:/usr/bin/X11:/usr/games:/usr/brlcad/bin:/usr/brlcad/bin
23:16.17brlcadwoah
23:16.27fotterbut it has failed to load...
23:17.03brlcadfailed to load?

23:38.20brlcadso yeah. thanks for your help :)
23:38.22fotterok, well if i'm around i'm more than happy to try and help... and from what i've seen of brl-cad so far i'm going to find it pretty useful
23:38.40brlcadyou did find the manual tutorial series on the website I presume?
23:38.46fotteryes
23:39.09brlcadif you change that block back to an if (0) { you should be back to working
23:39.17fotterso, i guess i would have hit other commands that wouldn't have worked? but fbclear comes first in the tutorial...
23:39.19fotterok cheers
23:39.20brlcadit's lower in the file
23:39.43brlcadyou wouldn't have hit many other commands that rely on the path
23:39.49brlcadslowly been decoupling from the path
23:39.50fotterah ok
23:39.58brlcadnirt might also have been a problem
23:40.05brlcadother than that, I don't know of another
23:40.18brlcadall the raytracers should be good
23:40.56fotteryes typing 'rt' into the command window worked just fine.
23:43.11fotterwell thanks. and as i said, if i'm around i'm more than happy to try things out if it helps - cheers!
