Fwd: chuck 1.3.1 on Windows 32-bit - possible OSC issue - update re: 1.3.1.1
by Simon Steptoe 15 Sep '12

Hi I've tried r.ck and s.ck on 1.3.1.1 and am getting the same issues as before. Either Chuck crashes immediately or soon after adding s.ck... or if things proceed, removing r.ck causes the crash. And it does seem the longer you leave things running, the more certain you'll get a crash when removing r.ck. Ditto for my own patches using OSC... although there have been times when things have run on for a bit without crashing near, or at, the very beginning.. which wasn't the case with 1.3.1.0. If things do get going there are two specific places where things go then awry.. at the first place the sound breaks down into "white noise" for a few seconds but the shreds continue unabated... the second place occurs a few seconds later with a "proper" crash. I only mention the first of these because I've never had happen at that point with previous versions of Chuck. To my eyes at least nothing particular stands out in the code at these points other than there are a lot of shreds active. Also, I've had the "OutOfMemory: while allocating stack" error message a couple of times. I'm not sure if the above is the sort of information that helps... but if there is anything I can do to provide additional info, please let me know. Simon ---------- Forwarded message ---------- From: Simon Steptoe <simonsteptoe(a)yahoo.co.uk> Date: 11 September 2012 09:45 Subject: chuck 1.3.1 on Windows 32-bit - possible OSC issue To: chuck-users(a)lists.cs.princeton.edu Some of my existing patches are causing Chuck 1.3.1 to lock-up and crash. I think I've traced it back to a possible OSC issue as the example files s.ck and r.ck seem to cause the same problem... which would make sense in that my affected patches are also using OSC events. If the patch gets going at all, removing the shred(s) also causes a crash. OSC_send.ck and OSC_recv.ck however seem to work fine. On my own patches I can sometimes catch the error message; "OutOfMemory: while allocating stack"... increasing buffer size and/or decreasing sample rate seem to alleviate the problem somewhat in that things keep running a few seconds longer, but eventually the result is the same. However, I guess this might not be the same issue as with s.ck and r.ck. Running Chuck with --silent doesn't resolve things either. My machine is Windows 7, 32-bit... to be fair it is a bit on the old side (Pentium 4)... but it's coped fine with previous versions of Chuck and miniAudicle.... and I can't replicate the issue with Chuck 1.3.0.2. Many thanks. Simon

Good evening Ge... I've tried r.ck and s.ck out on 1.3.1.2-rc1.. and.... I've yet to make it crash!! Also my own patches using OSC are performing as before (i.e. on 1.3.0.2) without a hitch. So, as least from my perspective, the latest fixes seem to have done the job. Thanks.

1.3.1.0 (chimera) [part 1]: 64-bit chuck
by Ge Wang 14 Sep '12

14 Sep '12

Dear all, chuck-1.3.1.0 (chimera) is available: http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ ChucK is, at last, 64-bit compatible. Lack of native 64-bit support has been a long standing issue with ChucK, and many people in our community over the last few years have contributed to making this happen. They include Kassen for his ever helpful voice of reason, Paul Brossier (who did a 64-bit port of ChucK 1.2.0.8 to ubuntu, a port that this release is largely based upon), Stephen Sinclair, who also provided a comprehensive and well-executed 64-bit port, and more recently Robin Haberkorn, who has jumped into the ChucKian development fire, as well as Michael Wilson -- your initiative and insights have definitely helped to make this happen. There have been many helpful discussions on chuck-users and chuck-dev, at CCRMA, as well as much encouragement and support from friends and colleagues like Fernando Lopez-Lezcano. ... Of course, had we/I architected the VM instructions to not make integer, float, and pointer size assumptions in the first place in 2006 with ChucK 1.2, it would have made things quite a bit easier for everyone. Yeah... Oops. This is the very first release of ChucK that natively support 64-bit as well as 32-bit. There are a few additional features (and likely a few new, uh, "features"). I imagine a few hot-fixin' rapid incremental releases might be needed. We have tried to test this thoroughly, in particular on Linux and Mac OS X, and less so on windows. To be totally honest, we have not been able to even test compilation for 64-bit on windows - if someone out there with access to 64-bit windows (XP or Windows7) who can give this a shot, that would be much appreciated! In general, users of all supported systems, please let us know if/how well this works for you! Part 2 -- on the way! Not unlike the final installment of the Harry Potter movies, or perhaps the video game ->Final<- Fantasy XIII (there is a FF XIII-2 and what is effectively FF XIII-3 was just announced), this 1.3.1.0 release will take place in multiple parts, mostly because Spencer is traveling to ICMC in Ljubljana, Slovenia, where he will present our paper on Chugins, Chugens, and Chubgraphs. Also, there is a little bit more work to do for 64-bit miniAudicle, so that's going to come in CK 1.3.1.0, part 2, and probably from Slovenia (it seems only fitting to release ChucK from the international computer music conference). Also, our dear friend Graham Coleman has asked about a chuck-1.3 version of (gasp) Audicle, so there might be a 1.3.1.0, part 2, b. As usual, please see the release notes at the end of this email. Thanks and Happy ChucKin, UpChucKin, Chugin'! gg!! ChucK on!! Best, Spencer + Ge, on behalf of entire chuck team --- 1.3.1.0 - (added) 64-bit support for all platforms (OS X, Linux, Windows) many thanks to Paul Brossier, Stephen Sinclair, Robin Haberkorn, Michael Wilson, Kassen, and Fernando Lopez-Lezcano, and all of chuck-users! - (added) Math.random(), random2(), randomf(), random2f(), srandom(), and Math.RANDOM_MAX; NOTE: randomf() returns range 0.0 to 1.0 these use the much better random() stdlib functions the existing Std.rand*() and Std.srand() is still be available for compatibility (these to be deprecated in the future; please start using Math.random*()) * (NOTE: on windows, Math.random() still uses the same generator as Std.rand() -- we hope to improve this in a future version!) * (NOTE: also see removed below) - (added) chuck --version | chuck --about now print architecture (32-bit or 64-bit) - (added) Machine.intsize() will return int width in bits (e.g., 32 or 64) - (added) examples/array/array_mmixed.ck to verify mixed-index fix (see below), based on Robin Haberkorn's test code - (fixed) multi-dimensional arrays now correctly support mix-typed indices (e.g., strings & ints) (thanks Robin Haberkorn) - (fixed) constants in Math library now cleaner, they include: * Math.PI * Math.TWO_PI * Math.e or Math.E * Math.i or Math.I or Math.j or Math.J // as 'complex' type * Math.INFINITY * Math.RANDOM_MAX * Math.INT_MAX // currently, differs on 32-bit and 64-bit * Math.FLOAT_MAX * Math.FLOAT_MIN_MAG // minimum positive float value - (fixed) Chubgraph.gain(), .last(), and .op() - (fixed) error message printing system for variable arguments - (fixed) StifKarp.sustain now works properly - (fixed) all examples now use Math.random*() instead of Std.rand*() - (removed) Math.rand*() removed --> please use Math.random*(); (see 'added' above; Std.rand*() still there, but to be deprecated; please use Math.random*() moving forward)

New error message appears in 64 bit
by John Ellinger 14 Sep '12

14 Sep '12

Hi, I'm using the latest ChucK 1.3.1.1 64bit on Mac 10.7.4. I've been getting this error message whenever running ChucK in the Terminal: [chuck]: cannot bind to tcp port 8888… ChucK programs continue to run fine, it's the first time I've seen this error message. I've been compiling the ChucK svn source code in Xcode for several months. The newest version compiles cleanly with no errors or warnings on Xcode 4.3.3. I've modified the Xcode project settings specifically to x86_64 and OS 10.7. This error string appears only once in chuck_main.cpp line 946. #ifndef __DISABLE_OTF_SERVER__ // log EM_log( CK_LOG_SYSTEM, "starting listener on port: %d...", g_port ); // start tcp server g_sock = ck_tcp_create( 1 ); if( !g_sock || !ck_bind( g_sock, g_port ) || !ck_listen( g_sock, 10 ) ) { >>>> fprintf( stderr, "[chuck]: cannot bind to tcp port %li...\n", g_port ); ck_close( g_sock ); g_sock = NULL; } else { ... } #endif // __DISABLE_OTF_SERVER__ In chuck_def.h "#define __DISABLE_OTF_SERVER__" is only defined if __CHIP_MODE__ is defined. I could not find "#define __CHIP_MODE__" anywhere in the 1.3.1.1 branch. If __CHIP_MODE__ is not defined, __DISABLE_OTF_SERVER__ is not defined, hence the error.

Chuck can't find my chugins ?
by Casper Schipper 14 Sep '12

14 Sep '12

Hi, I seem to have a problem finding my chugins with mini-audicle (version 0.2.2a (gidora)). When I try to load a compiled Chugin (located in /usr/lib/chuck I simply get : [Untitled]:line(1): undefined type 'Bitcrusher'... [Untitled]:line(1): ... in declaration ... any idea what is going on ? Should I compile them for 64 bits now for example ? Cheers, Casper

some bugs on windows ChucK
by Graham Coleman 14 Sep '12

14 Sep '12

Greetings, First, congratulations to chuck team and all responsible for the recent releases. I found a few bugs, these were tested in the latest ChucK and miniAudicle builds (win32) on 64-bit Windows 7 machines. 1. Machine.add doesn't seem to support drive specifications in paths. ( test1.ck) <<< Machine.add( "C:/Users/Public/test2.ck" ) >>>; //doesn't work <<< Machine.add( "/Users/Public/test2.ck" ) >>>; //works 2. A crashing bug when dealing with string non-literals. (test6.ck) I was unable to reproduce it outside of an OSC context, I don't know if it affects non-Windows systems. Basically, I was capturing string arguments from received OSC messages, and I found that one usage worked fine: <<< tsEvent.getString() >>>; //this should work but that trying to store it into a string object was crashing: tsEvent.getString() => string str2; //this should crash <<< str2 >>>; regards, Graham

Why does the gain increase each time through the loop
by John Ellinger 13 Sep '12

13 Sep '12

Hi all, After attending the SLEO conference last spring I was inspired to start a laptop group at Carleton College. I've run into a problem I don't understand. I'm using chuck version: 1.3.1.1 (chimera) mac os x : intel : 64-bit I've interfaced a 4x4 numeric touchpad to an Arduino controller that sends MIDI to Chuck. The MIDI reception works fine. I mapped keypad number 1 to a kick drum sample which works fine. The problem is every time I press keypad 1 the gain increases. This skeleton code illustrates the issue. ============================ // gain test SndBuf bufKick => blackhole; // change to your path "/Users/je/Documents/ArduinoXCode/midikeypad_git/chuck_pad/data/kick.wav" => bufKick.read; // set the kick gain 0.5 => bufKick.gain; // get the kick duration bufKick.length() => dur bufKickDur; function void playKick() { 0 => bufKick.pos; bufKick => dac; bufKickDur => now; } // infinite time-loop while( true ) { playKick(); 1::second => now; } =============================== I've tried things like this fun void playKick() { 0 => bufKick.pos; bufKick => Gain g => dac; g.gain() => float oldgain; bufKickDur => now; oldgain => g.gain; } and this fun void playKick() { 0 => bufKick.pos; bufKick => dac; bufKick.gain() => float oldgain; bufKickDur => now; oldgain => bufKick.gain; } but the gain still increases on every button press. How can I keep the gain at a constant level? It was a pleasure to meet and talk with Ge and Spencer at SLEO.

In v.1.3.0.2, I am getting bus errors with server/client stuff (Clix, Crystalis, etc.) Any thoughts? > line 3: 281 Bus error: 10 chuck pieces/Clix/server-multi_auto.ck I tried v.1.3.1.0 and I got even more errors. I reverted back to 1.3.1.4-beta and things were functioning well again. thanks, david David Loberg Code School of Music Western Michigan University 1903 W Michigan Ave Kalamazoo, MI 49008-5434 code(a)wmich.edu

1.3.1.1 (chimera) released (critical fix)
by Ge Wang 13 Sep '12

13 Sep '12

Greetings all! chuck-1.3.1.1 (chimera) is available: http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ This version fixes a critical issue that was introduced in 1.3.0.0 where member function calls in loop conditionals, paired with having an Object reference in the body, can cause a crash. This is quite likely the source of the OSC-related crashes that quite a few people have reported recently. It actually wasn't an issue with OSC (though we did tighten a few things there too), but rather the common usage: // e is an Event in this example while( e.nextMsg() ) { /* do stuff... */ } So, this should now be fixed (we think)! This issue was a rather serious one (the code above is commonly found when working with OSC, MIDI, HID, and any time a member function is invoked in loop conditional). We highly recommend updating to the latest as soon as convenient! Thanks to everyone who reported issues and helped to track things down! If you'd like, please do give 1.3.1.1 a spin, and let us if you run into additional issues -- we'll do our best to get things fixed as soon as we can! Thank you and ChucK on! Best wishes, Spencer, Ge + on behalf of chuck team! 1.3.1.1 --- - (fixed) critical bug since 1.3 where member function calls in loop conditionals caused crashes when the loop body contained local Object's to be released; this directly affects using OSC, MIDI, HID, which commonly employ syntax like: 'while( e.nextMesg() ) { ... }'; -- this is most likely the cause of the OSC-related issues we've been seeing (thanks to Graham Coleman for tracking down and narrowingthe issue!) - (fixed) strengthened synchronization in OSC between internal listener thread and chuck VM code - (fixed) memory bug in OscRecv deallocation - (fixed) Machine.add( ... ) on windows now supports both '\\' and '/' in aboslute paths (previously only '\\'). (thanks to Graham Coleman for finding this!)

toplap page
by Kassen 11 Sep '12

11 Sep '12

Hey all! http://toplap.org/ That is the new and far more exciting TOPLAP page. It's colourful, more friendly, and has no ChucK on it. Does anyone have a nice (recent-ish) video or write-up about livecoding with ChucK that they'd like to have there? I'd say "I could post that", but that would be a lie. It'd be more like "I should be able to post that" because I don't know how it all works, yet :-) Anyway, it needs some of our stuff chucked into it. Yours, Kas.
