ybityup, sadly01:19
ybitbut, it's only for a week01:20
ybitthe preparation01:20
xp_prgkanzure I am trying to present about my embryology experiment tomorrow night, can you be thinking of good papers I could reference please?01:22
kanzureyou haven't been reading any papers?01:34
xp_prgkanzure well I want to, was hoping you could guide me to some is all :(01:41
kanzureyay, I get to pick out some hardware for the lab01:41

gene_a 128X128 digital picture frame cost $10, this has 16384 pixels02:12
gene_if you can use maskless array gene synthesis to do 8 nucleotides per pixel02:13

kanzurefenn, have you seen this? http://www.pythonocc.org/10:47
kanzure"pythonOCC is a set of open-source Python bindings for OpenCascade, a 3D modeling & numerical simulation library. It currently wraps more than 7000 OpenCascade classes, that is, about 50% of the whole library content. pythonOCC may be distributed under the terms the CeCILL Licence."10:47
kanzureseems to have an odd license10:47
kanzurewhen I saw watchmen the other night, there was a line in the movie along the lines of ".. because anything free must be socialism, right?~~~ ", and the audience laughed. Shows that all hope is not, in fact, lost.11:09

kanzurefenn, have you seen this? http://www.pythonocc.org/13:10
fennlooking at it now, highly awesome13:11
fenni can't believe that guy who wrote pythonizer sat on it for six years13:11
kanzureI thought he was still sitting on it?13:11
xp_prgkanzure I have used opencascade13:12
fennhe is13:12
xp_prgit is a full scenegraph13:14
xp_prgit works on top of opengl and abstracts many 3d construction details13:14
fennsince you can use .dll's for the windows version i bet you can just use the libopencascade6.2-dev package13:16
fennsorry, libopencascade-dev13:16
xp_prgkanzure how do you hope to use it just curious?13:18
xp_prgwhat is pythonizer sat?13:18
kanzurefenn: shit.13:19
kanzurenow I feel silly13:19
kanzurehm, I can't apt-get it because libopencascade-foundation-6.3.0 does not exist13:20
fennaroo?13:20
xp_prgfenn what does he hope to use it for?13:20
kanzurexp_prg: why are you asking.13:21
kanzurego away.13:21
xp_prgjust curious, maybe I can help :>13:21
fennsudo apt-get install libopencascade-dev13:21
kanzurefenn: right.13:21
kanzuredoes it work for you?13:21
fennapt-get does, about to run pythonocc13:21
xp_prgyou can compile from source, I know how to do that kanzure13:22
kanzurexp_prg: why are you unable to read?13:22
kanzureI specifically said that I have compiled it from source.13:22
kanzurejeebus.13:22
xp_prgwell your doing apt-get install, you don't do that if you install from source13:23
kanzuredo you know why fenn suggested apt-get install?13:23
kanzureit's because I was compiling from source13:23
kanzureso he suggested apt-get.13:23
kanzurewhat's so hard to understand about this?13:23
xp_prgok :>13:24
fennah i'm so glad i finally turned on ignore13:24
fennoh great another fucking weird-ass french license13:26
kanzureah, I had backports in my sources.list, so I've fixed it now13:27
kanzurehttp://www.me.utexas.edu/~adl/links.htm  heh' we have a twitter feed13:35
kanzurefenn, how did you run pythonocc?13:36
kanzureI went into src/ and ran python setup.py, but then it doesn't find "module_builder'13:36
xp_prgkanzure usually it is python setup.py install13:37
fennyeah i can't find Utils/13:38
kanzurehm, I can't find 'swig'13:38
fenni dont know what CAS_ROOT is supposed to be either13:38
kanzureapt-get install swig.13:38
kanzureokay, now it's working, except g++ has now exited. blah.13:39
kanzureI need to go. will fight with this later.13:39
fenn*facepalm* out of disk space13:48
ybitnice find kanzure: pythonocc14:40
ybitor was it fenn... i'll read the log, still nice find14:41
fenni think debian's package is missing a number of files pythonocc expects14:42
fennStandard_ThreadId.hxx for example14:42
fennhey it's only 3 files that's not bad14:44
fennStandard_PCharacter.hxx and Standard_PExtCharacter.hxx14:45
fennoh. those are in 6.3 14:47
* fenn tries again with opennovation.org packages15:06
ybit13:10 < fenn> since you can use .dll's for the windows version i bet you can just use the libopencascade6.2-dev package15:06
ybit13:13 < kanzure> fenn: shit.15:06
ybit13:10 < fenn> since you can use .dll's for the windows version i bet you can just use the libopencascade6.2-dev package15:06
ybit13:13 < kanzure> fenn: shit.15:06
ybit13:13 < kanzure> now I feel silly15:06
fennybit: yes?15:06
ybithehe, i did the same thing nearly two weeks ago15:06
fennit turns out i was wrong15:07
ybitreally?15:07
ybitwhy so?15:07
fennpythonocc is meant to be used with 6.315:07
ybitah15:07
fennnow i'm trying a different set of packages15:07
fennif i have to compile OCC it's "the wrong way"15:07
fennwell i'm stumped15:26
fennit seems to mostly work, then fails on some obscure swig python error handling thing15:26
fennundefined reference to `PyExc_MemoryError' PyExc_IOError PyExc_RuntimeError PyExc_IndexError15:27
fennand so on for about  a thousand lines15:27
kanzure-_fenn: what are you stumped at in particular? did you get the 6.3 package from opennovation.org's repository?15:51
kanzure-_occ 6.3 successfully compiled, but then cd src/ ; make install hangs for a while. I suppose I should go run that in the background while I'm not actually at home sitting around.15:52
fennwell it seems to get past all the opencascade stuff and now i'm just stuck on some silly python/swig error15:53
-!- ybit is now known as hmatlock15:53
fennand yes 6.3 is from opennovation15:53
fennhttp://pastebin.ca/1356801 is what i did, more or less15:55
kanzure-_is your server still broken?15:56
-!- hmatlock is now known as heath215:57

heath_sorry for the nick changes15:57
fennapparently15:57

ybitbah, i'll stick w/ the original15:58
kanzure-_You don't have write acces to /usr/local/inc directory. Please use 'sudo python setup.py build'.15:59
kanzure-_OopenCascade CAS_ROOT environment variable not set.15:59
kanzure-_hrm.15:59
fennoh export CASROOT=/usr/share/opencascade/6.3.0/16:00
kanzure-_irssi asks you if you want to paste when the lines that you are pasting are more than 6. why isn't a plugin to dump the paste over the web installed by default?16:00
kanzure-_ah, I think I have to ln -s /usr/local/inc to point over to /usr/local/include16:00
fennyou're supposed to change environment.py :\16:01
fennand it should be /usr/include/opencascade not /usr/local/include16:01
fennyes, this is a pain16:01
kanzure-_error: package directory '/home/bryan/cad/pythonOCC-md0.1/src/../Utils' does not exist16:02
kanzure-_hrm.16:02
kanzure-_it's true, Utils does not exist in next to src/16:02
kanzure-_I didn't run 16:07
kanzure-_svn co svn://svn.gna.org/svn/pythonocc/trunk pythonOCC though.16:07
fenni dont think the Utils dir has anything important16:09
kanzure-_were you able to find the headers?16:09
kanzure-_oh right. 6.316:09
kanzure-_http://www.opennovation.org/debian/pool/main/opencascade/opencascade_6.3.0.dfsg.1.orig.tar.gz16:12
fennwhat about it16:12
kanzure-_guess I need to install it16:12
kanzure-_or at least the -dev package.16:12
fennget libopencascade-visualization-dev and libopencascade-ocaf-dev16:12
fennthat should get everything16:12
kanzure-_lots of undefined reference errors.16:15
fennok so at least it's not just me16:16
kanzure-_shouldn't there be something in /usr/lib/opencascade/ to represent compiled opencascade libraries that ld is supposed to link to?16:17
fenni think passing -shared to g++ should do something16:18
fenn(not that i have any clue what the problem is or what the solution is)16:18
fenneh guess not16:20
kanzure-_that involves editing setup.py?16:20
fennnevermind16:20
fennit already uses -shared16:21
kanzure-_https://mail.gna.org/public/pythonocc-users/2008-12/msg00000.html16:22
kanzure-_hm, it already uses g++ though16:22
kanzure-_https://mail.gna.org/public/pythonocc-users/2009-01/msg00002.html16:23
kanzure-_hah, there's like overall 2 total linux users of this package.16:23
fennyeah and i think they're using fedor16:25
fennunless you count the dev a user16:25

kanzure-_On my Linux Ubuntu 8.04 system, this generator fails to parse AdvApp2Var_* 16:26
kanzure-_headers and to generate the AdvApp2Var.i SWIG file. However, this file is 16:26
kanzure-_part of the /SWIG_src_modular_linux_darwin'. How is it possible? The answer: 16:26
kanzure-_I just copied/pasted the Windows AdvApp2Var.i file to this directory! And the 16:26
kanzure-_compilation works on Ubuntu 8.04 (in a sense, it's a miracle, that's why I'm 16:26
