11:35 LCID_Fire Does it make sense to call `createSurface` without checking result of `createWindow` in `ofAppEGLWindow::setupOpenGL`?

17:56 jedahan hmm where can i find instructions on getting 64 bit openframeworks compiling?
17:56 jedahan I am having trouble getting a 32 bit build of opencv, since the bundled one in ofxopencv is a bit out of date and I'm trying to evaluate a new feature extractor...
17:57 admsyn jedahan: on OSX?
17:57 jedahan yeah
17:58 admsyn IIRC everything should just work, except for the video stuff
17:58 admsyn as in the playback, due to Quicktime
17:58 jedahan so I just need to add a new build target for xbuild that is 64 bit and see how it goes?
17:58 jedahan coool
17:58 admsyn oh yeah, give it a shot
17:59 admsyn you'll probably get an error or two but I think it's doable
17:59 admsyn I think Carbon has its fingers in *something* still, but I don't remember what it is
17:59 admsyn I took a bunch out for 0.8.0 so we might be carbon-free at this point
17:59 admsyn (carbon is 32 bit)
18:01 admsyn if you go into build settings, under "Architectures" you should be able to just set it to 64-bit
18:01 admsyn probably won't need to make a new target / scheme, that might get a little tricky
18:06 tgfrerer_ joined #openframeworks
18:13 jedahan hmm yeah so it fails on qt like you said admsyn, gonna look at how to tell it not to try and build quicktime
18:14 admsyn I *think* you might be able to just take it out, assuming you don't need video playback :)
18:14 admsyn everything else in oF should just depend on the base ofVideoPlayer instead of an explicit dependency on QT
18:14 admsyn so you can probably just nuke it at the source :)
18:14 nicedice joined #openframeworks
18:15 jedahan nice
18:19 admsyn jedahan: o hey : https://github.com/NickHardeman/openframeworks_osx_64
18:24 tgfrerer_ joined #openframeworks
18:25 lukaszw joined #openframeworks
18:35 jedahan looks promising
18:39 fossterer Heyy people!!! I'm making progress day-by-day with your guidance...
18:39 fossterer now, i've an issue:
18:40 fossterer the frames are updated too slow on Android.. Am i seeking it right?
18:40 fossterer ***problem***
18:45 pizthewiz joined #openframeworks
18:54 jedahan admsyn aaaalmost compiles
18:55 jedahan complains about ___sincosf_stret being undefined, i wonder what library that is in
18:59 admsyn jedahan: any clues where that's coming from?
18:59 admsyn as in what lib it's in?
18:59 jedahan i think its system level
18:59 jedahan Yeah I think its because my openframeworks was compiled against 10.8 and my app 10.9
18:59 jedahan switching both to 10.8
19:00 admsyn yeah probably a good idea
19:00 jedahan yep that fixed it
19:00 jedahan ok so now i just have 5 symbol errors, related to opencv
19:00 admsyn a quick stack-overflowin-ing makes it seem like it's an Xcode quirk, the person just had to clean and build / restart xcode
19:00 jedahan gonna make sure i included all the dylibs i can and see if it goes away
19:00 admsyn cools
19:07 jedahan hmm can't find the symbols, but i know they are in libopencv_core.dylib...
19:07 jedahan welll, maybe I should check. Is there a utility to check the symbols in a dylib?
19:07 admsyn otool
19:09 bschorr joined #openframeworks
19:15 jedahan interesting, otool -TV is showing nothing, but nm -a shows the symbols i waant
19:15 admsyn are you getting a warning to the effect of "lib <whatever> ignored because it's for an architecture not being linked" ?
19:15 admsyn I forget what the actual wording is
19:17 jedahan only for libquicktime and the openframeworks target
19:17 jedahan which is fine
19:17 jedahan i am going to try and force opencv to compile against 10.8 and see if that helps
19:21 jedahan IT WORKS!
19:22 admsyn 🎉
19:22 jedahan ok, i might need to write this down
19:28 fossterer joined #openframeworks
19:33 jedahan scrap notes up at http://jedahan.com/2013/11/26/opencv-and-openframeworks-64-bit-on-mavericks.html , hooray
19:33 jedahan now to get lunch
19:53 GuidovanPossum joined #openframeworks
20:26 fossterer ohh.. solved!!! update() was doing too much stuff!!
20:27 admsyn that'll do it :)
