10:01.05 tarzeau when trying to build 7.10.4 on linux
10:06.15 Z80-Boy tarzeau: hi
10:06.20 tarzeau hi Z80-Boy
10:06.26 tarzeau clock!
10:06.36 Z80-Boy tarzeau: I am drawing the vgalamp schematic at the moment
10:06.40 tarzeau i'm trying with --disable-iwidgets-build
10:06.43 Z80-Boy The values of components were missing
10:06.45 tarzeau Z80-Boy: WOW!
10:06.48 Z80-Boy tarzeau: what's iwidgets?
10:07.32 tarzeau dunno something which cause problem to build it for me maybe
10:08.01 Z80-Boy libbreakcompile
10:09.59 Z80-Boy tarzeau: do you know what is franchise, rabatt and skoto with the krankenkasse?
10:10.14 Z80-Boy I got some complicated leaflet and now I realized I don't understand anything at all
10:10.49 tarzeau Z80-Boy: ouf, skonto is when you pay within 30 days you can take off 2% from the "rechnung"
10:11.04 tarzeau Z80-Boy: rabatt is another discount. no idea about franchise
10:11.56 Z80-Boy tarzeau: franchise is those 1500 2000 or whatever CHF
10:12.13 Z80-Boy tarzeau: who actually gives you the rechnung, the doctor or the krankenkasse?
10:12.26 tarzeau the krankenkasse?
10:13.00 Z80-Boy and if you have franchise 2500 and you go to a doctor for 300 then how much rechnung do you get? Full 300?

11:32.22 Z80-Boy brlcad: is it allowed to enter unnormalized vectors in put arbn8?
12:35.06 brlcad tarzeau: that's just a warning, fwiw, on the rcs_ident string -- an old-style identifier
12:35.54 brlcad iwidgets is a tcl extension package -- it doesn't actually have anything that compiles iirc, but disabling its building will tell it to try and use a system iwidgets library instead
12:36.39 brlcad i've not heard of any problems with iwidgets doing anything, so would be interested in hearing what, if anything, is going on with your build wrt them
12:38.28 brlcad Z80-Boy: afaik, that was the cause of the previous two bugs so the answer probably was no, but should now be yes if those were the only two issues

22:13.23 tarzeau brlcad: i'm desperately trying to build debian packages of brlcad, without success for a long time now, you can find the full build log here:
22:13.42 tarzeau brlcad: http://krum.ethz.ch/debian/brlcad/brlcad_7.10.4-1_amd64.build
22:17.55 trainman419 it looks like it's failing on iwidgets, do you have it installed?
22:31.36 brlcad yeah, you've specifically turned off iwidgets but then either it's not installed or it's not being tested for appropriately
22:32.50 *** join/#brlcad bpoole (n=bpoole@UNIX34.andrew.cmu.edu)
22:32.51 brlcad tarzeau: and I don't know if you've been listening in on the other conversations, but installing into /usr is presently highly ill-advised
22:33.19 brlcad if there's a system librt.so from gcc, it'll get clobbered by ours
22:33.40 brlcad potential other lib conflicts with libbu and libbn depending on what is installed aprior
22:34.12 tarzeau i tried without the disbaling iwidgets and that failed too
22:34.24 tarzeau i'd put the librt.so into /usr/lib/brlcad/ then...
22:34.31 tarzeau but i can't even get it to build :(
22:34.53 brlcad what's the error without disabling anything?
22:35.04 tarzeau let me see..
22:35.15 brlcad not disabling anything and enabling everything are the two most frequently tested configurations
22:35.35 brlcad they should both generally work unless there's a system misconfiguration or a bug in the build system
22:42.57 tarzeau it's still building...
22:44.16 tarzeau i know what the problem was
22:44.28 tarzeau i wanted to build with LDFLAGS and CFLAGS
22:44.34 tarzeau and leaving them away makes it work
22:44.42 tarzeau i've had this problem with another big software project
22:44.54 tarzeau let me give you the options that i used, that made it fail:
22:45.49 tarzeau CFLAGS="-O2" LDFLAGS="-Wl,-z,defs"
22:45.55 tarzeau try configure with these added at the end
22:50.59 trainman419 brlcad: is linux brlcad compatible with ATI proprietary graphics drivers?
22:52.04 brlcad trainman419: sure, shouldn't matter afaik
22:52.16 brlcad we don't require opengl
22:52.39 brlcad rendering occurs via ray-tracing or generic wireframe rendering
22:53.13 trainman419 well, when I try to use the framebuffer of an opengl window if makes the screen go all black
22:53.21 trainman419 X windows work ok, though
22:53.39 brlcad ah, sounds like "the opengl bug"
22:54.24 brlcad we've not been able to find the cause of that (bizarre) bug
22:54.58 trainman419 well, at least it's not just me
22:55.21 brlcad some bad interaction between opengl states and X11
22:55.30 brlcad --disable-opengl to work around it
22:56.03 brlcad doesn't remove any functionality, but does make that particular problem go away
23:14.00 trainman419 brlcad: so, the raytracer doesn't use any opengl acceleration other than framebuffer?
23:19.28 Maloeran It doesn't, it's all software
23:29.10 ``Erik BLAHHHH
23:34.49 Maloeran Hey Erik, how's life?
23:43.45 ``Erik continuing.
23:57.24 ``Erik heh
