00:00.27Axman6…not that i'd know what that is…
00:02.21louipcdoes anyone know how to discover vhosts on a domain?
00:03.29louipcaha I think I found something
00:03.29``Erikum, it came out in '87, axman...
00:03.37louipcAxman6: haaaah
00:04.11Axman6heh
00:11.33IriX64vmware is good....sound fx and music work
00:12.32Axman6yeah VMware fusion is really nice

00:13.43Axman6big improvment on using Qemu on a PPC i can tell you :P
00:14.43IriX64gotta buy this thing, they'll get sick of giving me eval licences eventually :)
00:20.53``Erikheh
00:21.01``Erikqemu x86 on an x86 is pretty decent
00:22.57Axman6``Erik: it almost perfectly emulated my 133MHz pentium 1 router thing. speed and ahrdware. i was pretty surprised

00:37.51starseekerHmm - did the changes made in incrTcl to support Tcl 8.5 in the tree render it unusable with 8.4?
00:53.06starseekershaders.rt.pix 0 off by many - anyone else seeing this fail in the regression test?

01:20.32``Erikyes
01:20.42``Erikthe internals changed between 8.4 and 8.5
01:20.49``Erikand incr pokes at internals
01:55.49starseekerOK, configure needs to select internal now if it detects 8.4 - it barfed on my machine
02:03.30``Erikif the system has the correct incrtcl installed, it can use 8.4...
02:03.45``Erikthe issue is between incrtcl and tcl, not anyhting of ours
02:09.29starseekerHmm.  OK, BRL-CAD on my system has never liked the system incrtcl
02:14.56starseekerIt's trying to use the BRL-CAD version, and configure is checking the system version of tcl/tk and saying "oh, OK, 8.4 is fine."  Then it doesn't like my system incrtcl and Bad Things happen...
02:26.27starseekerCool - the simple brep example is fun to play with
03:08.09*** join/#brlcad starseeker (n=CY@c-68-33-217-173.hsd1.md.comcast.net)
03:14.27brlcadstarseeker: 0 off by many isn't a failure
03:15.05brlcadand .. which simple brep example? :)  there are three of them
03:15.27brlcadneed to get rid of one of them as soon as some more testing gets done
03:26.59starseekerbrep_simple
03:27.14starseekerbrep_cube is crashing for me atm
03:27.27brlcadreally?  that's odd
03:27.33brlcadsame file, just different values
03:27.38starseekerERROR: NULL struct db_i pointer, file db_lookup.c, line 237
03:27.48brlcadooh
03:27.57brlcadit's expecting an argument
03:28.03brlcadi forgot about that
03:28.07brlcadi fixed it in simple
03:28.19brlcadjust not yet in cube
03:28.26starseekerheh - brep_cube --help works :-)
03:28.38brlcadcube is the one that should go away
03:29.14brlcadbreplicator is the third -- it basically performs the same steps as brep_simple but in a linear fashion so you can see more explicitly what's going on
03:29.53starseekerI can't rotate the brep_simple in mged, but subtracting "normal" primitives works :-)
03:30.26starseekerGenerates a nifty screenshot, but I can see raytracing these suckers is going to be resource intensive
03:31.02brlcadthat's very much experimental, what's currently being worked on
03:31.10starseeker:-)
03:31.15brlcadnot been optimized at all, still working on implementation
03:32.32brlcadray-tracing breps is probably about 90% done
03:34.14starseekerNifty!
03:47.13starseekerMeh - archer doesn't like Linux atm - Error in startup script: invalid command name "bu_brlcad_root"
03:50.07louipcstarseeker: did you ever get it to run in linux?
03:50.37starseekernot so far
03:50.39starseekerbbl
03:50.47louipcyeah me neither
03:51.17brlcadrun bwish, does bu_brlcad_root work there?
03:53.03brlcadotherwise, you're either not running archer through bwish or Bu_Init isn't getting called
03:53.48louipcbu_brlcad_root to specify what? Usage: bu_brlcad_root subdir
03:54.10brlcadusage is what it should say
03:54.18brlcadit's a function that returns the location of the root
03:54.20louipcyep ^
03:54.24brlcador an item in the root
03:54.31brlcadbu_brlcad_root .   for example
03:54.41louipcok
03:54.43brlcadbu_brlcad_data db/moss.g
03:54.55louipcit gave the usage message with a blank argument anyways
03:55.36brlcadwhich is why invalid command name should only happen if it's not bwish/btclsh
03:55.46louipcthere's some problem with tkimg.so and pnglib in archer. I was actually tinkering with it before to try and figure out what was going on
03:56.34louipc... well for me anyways
03:57.20louipcError in startup script: couldn't load file "/opt/brlcad/lib/tkimg.so
03:57.35brlcadis it there?
03:57.46louipcyep
03:58.12louipcI think I got it to load before but I was still having png_read_destroy error
03:58.20brlcadrun bwish and type "load /opt/brlcad/lib/tkimg.so"
03:58.24brlcadwhat's it say?
03:58.54louipcundefined symbol: png_read_destroy
03:59.03louipccouldn't load file "/opt/brlcad/lib/tkimg.so
03:59.30brlcadthat'd be why
04:00.11brlcadit's got an unresolved symbol to that png function, and the libpng that it's finding probably isn't exporting it
04:00.44louipcoh so I'd have to rebuild my libpng or something
04:01.16brlcadthat's my guess
04:01.30brlcadcould also be something in tkimg, if that's not a libpng function
04:02.11louipccould be deprecated *shrug*
04:02.42brlcadyeah, looks like it might have been removed from libpng
04:02.49brlcadhttp://www.redhat.com/archives/fedora-extras-commits/2007-October/msg07881.html ..
04:03.26brlcadthat removes it
04:03.26brlcad(from tkimg)
04:05.49brlcadhave to look into it more later, but you can probably work around the problem with --enable-libpng
04:06.01brlcadsince our libpng is explicitly set to export it iirc
04:06.21louipcI think I'll try to make an archlinux package for tkimg
04:06.29louipcI didn't even notice it was there
04:06.48brlcadit's a small/simple little extension
04:19.21louipcah OK I remember what happened
04:20.00louipcLoadArcherLibs.tcl line 65 I put the path of my libpng.so which got rid of that error
04:20.14louipcbut there was a new error Error in startup script: couldn't find procedure Png_Init
04:29.45starseekerAh - it looks like archer is trying to use my system tcl/tk despite BRL-CAD having built its own copy
04:30.02starseekermutter mutter...
04:30.18louipcstarseeker: do you know anything about Png_Init?
04:30.35starseekerziltch, I'm sorry to say
04:30.40louipcshucks
04:31.15louipcI just grepped the libpng source tarball and it comes out null
04:31.31starseekerIt's probably a TCL/TK routine
04:31.41starseekerwhere does it grep out in the BRL-CAD tree?
04:32.21louipctkimg.so!
04:32.36starseekerOK, so the tkimg src is the place to look
04:32.54louipcyep I'll go about making a separate package when I get the chance
04:34.08starseekerWhere's the magic where mged selects the local tcl/tk packages?
04:34.26louipcmged? i dunno :P
04:34.35starseekerIt's doing it but archer isn't
04:35.29louipcwhoa mged is binary
04:36.51starseekerGrr
04:37.21starseekerJust trying to run /usr/brlcad/bin/bwish outright results in the /usr/lib/tcl8.4 libraries being used
04:37.37louipchmm
04:38.46starseekergrr - rtwizard does the same thing!
04:39.06starseekerWild - it looks like only mged (so far) is doing whatever the "right thing" is
04:39.47starseekerand I still can't get itcl/itk to work from the system side
04:39.58louipchah I thought mged used bwish
04:40.18louipcI'm not even going to bother with that :D
04:40.34starseekergrepping in src/mged doesn't have a single match with wish
04:40.41louipcmy knowledge is too limited
04:40.55starseekerconfound it
04:41.34louipccould be a configure thing though
04:41.53starseekerMaybe...
04:42.01starseekerI'll build clean

05:25.18brlcadlouipc: the Png_Init (and pretty much any [lib]_Init) function is a tcl hook function that gets automatically called during a load or package require
05:26.10brlcadit's not a png function, tkimg provides one because it has a png image loading interface, so there's a Png_Init for that submodule to tkimg
05:27.29brlcadmged does not use bwish, it has an embedded interpreter just like bwish does
05:28.51louipcah mged's command interface seemed identical to bwish
05:29.08brlcadit's very similar
05:29.20brlcadthough not strictly identical
05:29.34louipcis there a reason for having both?
05:29.47brlcadthey serve entirely different purposes
05:30.13louipcoh
05:31.05brlcadbwish is basically "wish" with brl-cad resources preloaded so you can write brl-cad tclscripts more easily and have access to many of the same commands that are in mged (like bu_brlcad_data)

05:34.06louipclike a tcl script?
05:34.27brlcadthere are already the needed [lib]_Init() routines, just need the pkgIndex.tcl files to get written/generated

05:58.36yukonbobq: is the brep (ie: brep_simple) support only in HEAD?
05:58.46brlcadafaik, all that's needed is making a tclcad_Init() and a pkgIndex.tcl script for tclcad, bu, bn, rt, dm, fb, and pkg
05:59.04brlcadyes, only in head
05:59.34brlcadit was in the last release, but won't compile by default without editing configure.ac
