17:02 kimmie On OSX, when I set a resolution in a call to ofVideoGrabber.initGrabber, does that actually change the resolution that the camera transmits? Or is there some resampling done somewhere? I am trying to decrease USB-bandwidth to be able to use more cameras.
17:04 admsyn I'm pretty sure it does
17:04 admsyn unless QTKit is doing resampling, which I doubt
17:06 kimmie admsyn: Ok, thank you. Even if I set it ridiculously low I am not able to have more than one USB-camera connected to one USB-bus, which is odd to me, that is why I wondered. Thanks though.
17:07 admsyn ah that's a shame. Video's not really my forte so maybe someone else in here will know more about that
17:07 admsyn you could try the AVFoundation grabber though
17:07 admsyn it's just an addon right now
17:07 admsyn not sure if it's "done"
17:08 kimmie Nice idea, I will try that.
17:11 kimmie admsyn: Oh, it seems that is for iOS only though.
17:11 admsyn :/
17:13 kimmie Why isn't everything USB3 already? :)
17:13 admsyn I know right

19:48 RBB has anyone used OF 0.8.0 with Code::Blocks 12.11?
19:49 admsyn I know that it was one of the things that was supposed to have been fixed in 0.8.0..
19:49 admsyn are you having issues?
19:51 RBB yeah, I looked at the cbp file from the project generator and then the options in CB and it doesn't list any of the linked libraries / search paths
19:51 RBB sorry I might be doing something wrong, I've never done any c++ development
19:51 admsyn so, it's not linking against freeimage freetype etc correctly?
19:52 RBB yeah in the project build option under link libraries and search directories its all blank
19:52 RBB but they're all listed in the cpb xml
19:53 admsyn alright, and then when you build you get linker errors or something like that?
19:53 * admsyn is not familiar with code blocks at all
19:54 RBB the build errors are undefined reference to _...
19:55 RBB ..\..\..\libs\poco\lib\win_cb\libPocoN​etSSL.a(SSLManager.o):SSLManager.cpp|| undefined reference to `__gxx_personality_sj0'|
19:55 admsyn eek :/
19:57 admsyn a bit of googling makes it sound like it's using gcc instead of g++
19:57 admsyn I'm not quite sure how you'd go about checking that in code blocks.. is there anywhere in the UI that's saying which compiler version it's using?
19:57 RBB g++ isn't listed on the compilers, but I know it was installed with MingW
19:58 admsyn yeah this is all out of my realm unfortunately…it kind of looks like the wrong compiler is being used, but that's all I got
19:58 RBB well thanks for trying
20:01 RBB from the build log it uses mingw32-g++.exe
20:01 RBB it does look like it lists the libraries on the command after -s
20:02 admsyn this looks relevant : http://stackoverflow.com/a/7751743/704596
20:02 admsyn does it help at all if you do what smallB says?
20:03 admsyn I think what's happening is that all the libs were compiled in one windows compiler, but code::blocks is trying to use an incompatible one
20:03 admsyn I was under the impression that was kind of figured out in 0.8.0, but windows isn't really my thing :/
20:06 RBB is the linker a seperate process?
20:07 admsyn yeah, so the compiler will hit your code first, and will generally give you sane errors like "file x not found" and "this thing isn't compatible with that thing", then the linker stitches it all up and produces impenetrable errors like the ones you're getting :)
20:10 RBB I saw some stuff about compiler version on the forums, but I don't know what version the CB libs were compiled with, I believe the one its trying to use is 4.5.2
20:11 bakercp joined #openframeworks
20:11 admsyn hey @bakercp, are you familiar with code::blocks and or windows compilers?
20:11 bakercp … codeblocks -- a little bit.  windows compilers, still getting my head around them.
20:12 bakercp it's on my todo list though … i've got a lot of addons to test on windows … :)
20:12 admsyn RBB: is having a bit of a linking issue that *seems* to be related to using a compiler incompatible with the pre-built oF libs in 0.8.0
20:12 bakercp i was going to have a go with VS2012 in the next few days.
20:12 admsyn error in question -> ..\..\..\libs\poco\lib\win_cb\libPocoN​etSSL.a(SSLManager.o):SSLManager.cpp|| undefined reference to `__gxx_personality_sj0'|
