@asdofindia, I tried to replicate your first issue, and couldn't. Have you modified your Erlang install ?

The second issue is likely related to your audio setup and SuperCollider. You may need to install some adapter like you said 'pipewire-jack' (, which I don't think should be a dependency of this package.) I encourage you to take a look at SuperCollider documentation.

I installed the whole erlang package and retried and the previous error didn't come up again, and it installed successfully. For reference these were the packages that got installed:

$ sudo pacman -S erlang

Although it had problems starting.

sh: line 1: pw-jack: command not found

This could be fixed by installing pipewire-jack

But then in the CLI

Error. Unable to write to log file: closed stream
#<IOError: closed stream>

and in the GUI

Sorry, the Audio Server failed to start... 
Please try changing your default OS audio input & outputs. 
Note, the audio rate of the inputs & outputs must be the same. 
For the curious among you, Sonic Pi uses the SuperCollider Audio Server to generate its sounds. By default it will connect to your default system audio input and outputs.
Unfortunately SuperCollider is having problems starting correctly. You can read the full error log below which should explain why.
To fix this you can try changing your default operating system audio inputs and outputs (ensuring they have the same audio rate).
Advanced Users - you may manually override this and further configure how SuperCollider boots by editing the file: /home/asd/.sonic-pi/config/audio-settings.toml

    Aborting...

@naxil the patch is out. The issue arose from the upstream boost version, which deprecated the 'system' lib. I have produced a patch, expecting everyone to use the latest boost version, therefore running into this issue. Please report if anything.

@naxil thanks for your report, the problem is sadly on the sonic-pi codebase side. I'll try to provide a patch in the meantime.

On a quick test, I've uninstalled sonic-pi-git, then uninstalled a bunch of orphan packages. I have not uninstalled all of the sonic-pi-git dependencies, as some of those are need by some other packages on my system. Thus, this test is incomplete.

Then, I installed it again, and it compiled and ran successfully.

Then I uninstalled elixir and erlang-related deps, and it still ran successfully. So, yeah, seems to work for me. Thanks! (Now I need to learn how to live-code some music… Well, there is a long tutorial to learn.)

@denilsonsa: Thanks for pointing the dep issue. I have, aggressively, recreated the dependencies list. It could be that some makedeps are actually runtime dependencies, waiting for your feedback ;0

@brany: I'm terribly sorry! I got confused! The out-of-date sonic-pi package is broken. This one is the -git package, which is up-to-date and doesn't have that issue.

However, I'm getting a different issue:

[100%] Built target sonic-pi
Compiling Erlang/Elixir files...
** (Mix) The application "asn1" could not be found. This may happen if your Operating System broke Erlang into multiple packages and may be fixed by installing the missing "erlang-dev" and "erlang-asn1" packages
==> ERROR: A failure occurred in build().

I believe this can be solved by adding erlang-asn1 as a dependency. Not sure if build-only or also runtime.

And then it complained about public_key, which means installing erlang-public_key.

And then it complained about ssl, which means installing erlang-ssl.

And then about erlang-parsetools.

And then about erlang-sasl.

You may want to add those as deps. ;)

@denilsonsa: Hello, I cannot reproduce your error. Also, there is no such file as gui/qt/CMakeLists.txt in the sonic-pi repo. Are you sure this error is related to sonic-pi-git itself ?
