faust chugin compile errors
by d 31 Aug '23

Hi all I compiled the latest (chuck-1.5.1.2) and chugins on linux , but the faust chugin thows an error when compiling. I changed SAFE_DELETE to CK_SAFE_DELETE and it compiled without error. ----------------------------------- g++ -c -o Faust.o Faust.cpp -pthread -D__LINUX_ALSA__ -D__PLATFORM_LINUX__ -I../chuck/include -fPIC -O3 Faust.cpp: In member function ‘void Faust::clear()’: Faust.cpp:252:9: error: ‘SAFE_DELETE’ was not declared in this scope; did you mean ‘CK_SAFE_DELETE’? 252 | SAFE_DELETE(m_dsp); | ^~~~~~~~~~~ | CK_SAFE_DELETE ----------------------------- But chuck does not seem to find it $ ls /usr/local/lib/chuck/Faust.chug /usr/local/lib/chuck/Faust.chug ------------------------------- $ chuck clarinet.ck [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or resource busy. [chuck]: RtApiAlsa::probeDeviceOpen: unable to synchronize input and output devices. clarinet.ck:5:1: error: undefined type 'Faust'... [5] Faust clarinet => dac; ^ clarinet.ck:5:1: error: ...in declaration [5] Faust clarinet => dac; ^ [chuck]: RtApiAlsa::probeDeviceOpen: unable to synchronize input and output devices. [chuck]: RtApiAlsa::probeDeviceOpen: unable to synchronize input and output devices. ------------------------- also.. I am using pipewire , it works fine, but I get these annoying messages ------------------------------- $ chuck krstlchr-algo7.ck [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or resource busy. [chuck]: RtApiAlsa::probeDeviceOpen: unable to synchronize input and output devices. [chuck]: RtApiAlsa::probeDeviceOpen: unable to synchronize input and output devices. Play some nice open chords... Then loop on random open circle of 4ths notes... thanks for chuck! d

chuck-1.5.1.0 (chai) released
by Ge Wang 11 Aug '23

Dear all, chuck-1.5.1.0 (chai) has been released: https://chuck.stanford.edu/release/ WebChuck & IDE have also been updated to 1.5.1.0: https://chuck.stanford.edu/webchuck/ https://chuck.stanford.edu/ide/ what's new? (full release notes) https://chuck.stanford.edu/release/VERSIONS =============== Some highlights =============== This release (1.5.1.0) updates a long-standing policy regarding `return`statements in function declarations (see below); added @array.sort(); added new command-line option (--pid-file), useful for process monitoring in long-running installations; general bug fixes and stability improvements. --- NEW: the chuck compiler now rejects non-void function definitions in which not all control paths return a value, and will print a compiler error in the form of: "error: not all control paths in 'fun int f()' return a value" RATIONALE: while *** this may break some existing code (apologies!) *** that assumed the previous return semantics (or forgot to return a value or accidentally declared a function as returning something when it should return `void`), we believe this change will be more beneficial in the long term and will lead to clearer, more intentional code. --- FYI much has been added recently between 1.5.0.0 and 1.5.1.0: * new for-each loop syntax for iterating through arrays (1.5.0.8) * enhanced and more accurate compiler error reporting; now highlights code and pinpointing error location in code (1.5.0.5) * detection and reporting for out-of-order dependencies (1.5.0.8) ...the cause of much mysterious behavior and crashing previously * color terminal support for CLI chuck (1.5.0.5) * expanded class library support in IO, random number generation, Machine.eval(), chugins management, and array * new features in CLI chuck, miniAudicle, WebChucK & IDE * (developer) streamlined c++ integration for those wishing to incorporate ChucK core into other c++ hosts (1.5.0.7) https://github.com/ccrma/chuck/tree/main/src/host-examples Our work is never done. Here's to supporting research, teaching, and art-making.
