Hello chuckians There was an error when I compiled Fauck. llvm-config was not found. I did not notice it at first because the compile was successful. The linux distro I am using (devuan) used the name llvm-config-15 rather than llvm-config I modifed the makefile and that eliminated the error. And the chugin shows up in the chugin probe. But now.. chuck fau.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. terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Aborted d On Sun, 27 Aug 2023 15:40:16 -0700 d wrote:

thanks for the quick response!

chugin-probe reveals an error:

[chuck:2:SYSTEM]: | | [FAILED] chugin 'Faust.chug' load... [chuck:2:SYSTEM]: | | | reason: /usr/local/lib/chuck/inactive/Faust.chug: undefined symbol:_ZTVN4llvm24IRBuilderDefaultInserterE

looks like I may be missing something llvm i have libllvm15 llvm-15-dev llvm-15-linker-tools llvm-15-runtime llvm-15-tools lld-15

Thanks for the report! Inline responses below:

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 -----------------------------

Good catch. We have pushed the CK_DELETE_* macro update to chugins repo main branch.

...

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.

[5] Faust clarinet => dac; ^ clarinet.ck:5:1: error: ...in declaration [5] Faust clarinet => dac; ^

There are few tools for diagnosing chugins at runtime:

1) run `chuck --chugin-probe` to see what chugins would be loaded (and from where) 2) run `chuck clarinet.ck` with the -v3 (verbose level 3) to see what chugins are actually loaded (with more error reporting here)

What do you see? Any errors?

------------------------- 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.

We have updated the error reporting where warnings will now only be printed on verbose level 4 ("WARN") or higher. Also fixed a bug that resulted in false positive error reporting on linux ALSA. These will be part of the next release, 1.5.1.3.

...

thanks for chuck!

thanks for chucking!
