Greetings all! chuck-1.3.1.2 (chimera) is available: http://chuck.cs.princeton.edu/ http://chuck.stanford.edu/ This release addresses some of the recent issues discussed on this list, includes 2 important bug fixes, and adds automatic sample rate detection for JACK as well as others. release notes are copied below. Once again, thanks to everyone who reported issues and helped to track things down and test! Please continue to let us know if you run into any issues! Thank you and keep on ChucKin'! Best wishes, Spencer, Ge + on behalf of chuck team! 1.3.1.2 --- - (added) chuck now automatically detects and uses next highest or closest (in that order) system sample rate in the case where the default is not available; if a sample rate requested via --srate: is not available, an error will be encountered with a message. - (fixed) base parent object is correctly accounted for by new shred when sporking member functions (thanks to Michael Heuer for reporting and narrowing this down) - (fixed) popping local variables from the operand stack in cases where the datatype size is larger than int-size; this is a bug introduced with 64-bit in 1.3.1.0, and exhibited on 32-bit systems only. (thanks to Simon Steptoe reporting and narrowing this down) - (fixed) opening real-time audio with 0 input channels should now work, once again.
