Carla: update to 2.4.1 (with fix to non-explicit cast with Python3.10)

[Animeshz]

Older version breaks on Python 3.10, see: falkTX/Carla#1489. PR simply bumps the version.

Have the results of the proposed changes been tested?

• I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me
• I generally don't use the affected packages but briefly tested this PR

Does it build and run successfully?

(Please choose at least one native build and, if supported, at least one cross build. More are better.)

• I built this PR locally for my native architecture, (x86_64-glibc)
• I built this PR locally for these architectures (if supported. mark crossbuilds):
  • aarch64-musl
  • armv7l
  • armv6l-musl

Seems like Carla itself does not support musl-libc.

see #23390

Seems like Carla itself does not support musl-libc.

If you want to dig into it, create a patch for musl, add it to our package and submit it upstream, that would be nice. If you don't, we should fix this package anyway, so let's only patch our current version: https://github.com/falkTX/Carla/commit/3316618aa57346be5b0ab8667deab0dba7ba8c68.patch.

Ok, might try tomorrow!

whyyy

__linux__ should work better than __gnu_linux__ there, I didn't even know about __gnu_linux__.

https://github.com/falkTX/Carla/blob/25c61989de0cfe55e4ff62af002403c9acaa1bd6/source/modules/juce_core/juce_core.cpp#L95 remove this line entirely.

And please ask upstream to replace their hardcoded platform knowledge with a simple configure check.

[Animeshz]

Done! Builds in x86_64-musl, haven't tried others (I have data caps).

Rebased over the latest tip 👍

It seems to be stuck continuously loading DSP and pressing the New button doesn't do anything.

Also, per #23390, this is missing the liblo dependency.

Does this happen for you? Any tips on what to investigate? I don't know if it's because I'm on musl...

Sorry if I am missing something but DSP load is not for "loading DSP", but is just an indicator of how much time the last frame took over the maximum amount of time available based on the sample rate and buffer size:

As for the "new" button. That just resets the rack. If there are no plugins/VSTs loaded, then it will do nothing:

This is why I was asking :)

Good to know it isn't broken, I will try to merge this soon.
