Bus Error - Trying to run ChucK for the first time
by jimmak cataract 13 Mar '05

13 Mar '05

Hello, I am an ultra-newbie trying to run ChucK for the very first time, and am experiencing difficulties trying to run any of the demos. The source compiled well on OSX 10.3.7, and trying to run ChucK without any input yields: [chuck]: no input files ...... (try --help) which is what the install readme says should happen (?). However, when I try to run any examples, for example demo0.ck, I get a bus error. The last paragraph in the console output says: JAR: DeviceSetProperty inSelf 17915232 JAR: DeviceSetProperty 'sfmt' JAR: Sample Rate: 44100.000000 JAR: Encoding: 1819304813 JAR: FormatFlags: 43 JAR: Bytes per Packet: 4 JAR: Frames per Packet: 1 JAR: Bytes per Frame: 4 JAR: Channels per Frame: 1 JAR: Bits per Channel: 32 time=0.0000s Bus error The jack server is running, and I have the same thing using portaudio as the driver (not coreaudio), as well as built in audio, and not my sound card. Could someone give me some direction in getting this to work? Thanks alot for your time, regards, Stuart Woolford. Australia. ChucK 1.1.5.4 dual 800MHz Quicksilver G4, 768 Mb Ram, Interface: Delta Audiophile 24/96 OSX 10.3.7 _________________________________________________________________ Searching for that dream home?

Has anyone got the net_send.ck and net_recv.ck examples to work? On the receiving machine I get: [chuck](via netin): dropped packet, expect: 2 got: 1377501184 Segmentation fault Tested this on both OSX and Debian. Any suggestions? ttg

jack transport

hello! i'm playing around with jack and wonder if chuck could be jack transport client? http://jackit.sourceforge.net/docs/reference/html/transport-design.html start and stop commands should be doable, but repositioning seems to be paractical impossible for some patches, what do you think?

status report

Dear All, chuck-1.2 is on the way. (but this email will reach you before it does.) As you may (or may not) be wondering: it is now February, where is ChucK-1.2? We have pushed back the release (again), this time to March. However, this _will_ be the final delay. We have been busy writing papers (one of them, ironically, is about implementing ChucK) in the last month or so, trying to meet submission deadlines (3 of which fell within the same week). We are on the last spin cycle of paper writing, and can return to full-time development on 1.2 in 2 weeks. You may be wondering: how can we guarantee a March release? Answer: we release what we have at the end of March, even if some things are not yet done. As for the actual status of the new release: --- done: - 90% code/testing the new type system, which supports arrays (both integer and associative), defining new objects, environments/contexts for organizing the namespace, new operators (+=>, *=>, ^=>), object references, many small fixes. - 50% code/testing the emitter and new virtual machine bytecodes. Not too much code needs to be written for supporting arrays/objects - heavy testing is very much needed. - various fixes in all parts of the system todo: - the other 10/50% of system - function overloading - more powerful library import mechansim - more powerful unit generator import mechanism - a very basic class library - stereo/multichannel support - testing testing - documentation for new features in progress: - Adam Tindale is putting together (gasp) comprehensive documentation - Ajay Kapur has been investigating using ChucK for real-time controllers - Phil is researching more graphics-related Audicle/gluck ideas - Folks at Stacken have been working on auto-conf (now waiting for us to hand over new release) - Gary Williams is working on tutorials in the beginning chuck blog - Chris Turner is working on matching client/server messages for better on-the-fly programming feedback - Perry, Ananya, and I are writing paper and code for v2 - (any other development effort I missed?) release dates: --- v1.2 release: late March doc overhaul release: April audicle release: summer gluck release: summer In conclusion, we apologize for the delay and thank you for your (incredible) patience.

From the performance standpoint, I can say that the Audicle is much more than a fancy editor / visualization. We have to keep in mind that this language aims to facilitate on-the-fly programming. The Audicle interface substantially changes how a performer might interact with Chuck in realtime, because it fundamentally changes the characteristics of the performance interface. > > But this stuff is completely optional, you can also do everything with > plain chuck and an editor of your choice. Except that you can do it more quickly and in different ways using Audicle. Plus our plain editors are way less interesting to audience members than are fancy visualizations. > I don't think it makes any sense to try to make Audicle more screen > reader friendly, because it's mainly 2D and 3D visualization.

Have you tried to run chuck? Is there anything which > could be improved for a screen reader...? As a composer/performer, I personally prefer virtual instrument GUIs of some kind (even if they're dynamically defined) over command line interfaces for performance. We need to get away from the suspicion that your new music laptop performer is in fact checking his e-mailing during the performance you're watching, and projecting visualizations--especially visualizations like this that are integrated with the code editor and are apparently effecting the way in which the performer makes musical decisions--has a lot of potential as a cure. --Jeff Treviño, Stanford University Computer Center for Research in Music and Acoustics (CCRMA) > > > > Rich Caloggero wrote: >> Somewhat dumb question here -- what exactly is >> Audicle ?

Dear All, We are happy to announce that the Audicle has won the 2004 ICMA Best Presentation Award, as voted by attendees of the 2004 International Computer Music Conference (ICMC), in Miami. The video of the presentation is now available for bandwidth and storage abuse (they are pretty big) - if you want to take a glimpse at the audicle: http://soundlab.cs.princeton.edu/listen/ big: audicle_icmc2004_sm.mov (130 megs) bigger: audicle_icmc2004.mov (500 megs!!!) Thanks to Ajay Kapur + Adam Tindale for filming the thing, and for everyone's support! Best, Perry, Phil, Ananya, Ge

While testing my ModalBar program, ChucK crashed. I'm enclosing the program (mb419.ck) and the tech error text Windows produced (70d5_appcompat.txt). System Windows XP (with SP2) on a Sony Vaio laptop.
