The online compiler seems not to produce uptodate SuperCollider UGens

I tried this both with some of my own code, and with 'Small Example' from the playground. Generate the files and install them in the extension directory in SC. When you boot scsynth:

ERROR: API version mismatch: /Library/Application Support/SuperCollider/Extensions/Small_Exemple.scx
    This plugin is not compatible with SuperCollider >=3.9.0
    The plugin has not been loaded; please find or compile a newer version.
    (Plugin's API version: 2. Expected: 3)

SC 3.9.0 is almost 3 years old, so this seems like a longstanding issue. It seems like I did build successfully with the faust2supercollider script so seems like an online compiler only issue. I will try to investigate.

• hum, seems strange since the SuperCollider architecture has not changed recently, and so the online compiler uses a quite uptodate version.
• on which OS does it happens ?
• yes please investigate thanks.

Sorry, OSX 10.14, but I'm sure that's not the issue. It's building to the old UGen API. Here's where the error happens: https://github.com/supercollider/supercollider/blob/f806ace7bd8565dd174e7d47a1b32aaa4175a46e/include/server/ErrorMessage.hpp#L78

Yeah, as I said 3.9 was Jan 2018, so yeah quite some time ago. I confirmed again that I can build with faust2supercollider. Ironically the newest version of faust I seem to have is from 2016, so that's strange in itself! Sorry haven't used this stuff for a while!

@orlarey could is be an issue with what is installed in the Docker image to produce the SuperCollider OSX binary plugin?

I can confirm the issue, I have the same exact problem asking to be compiled with a newer version: ERROR: API version mismatch:... SC 3.11.2, MacOS 10.15.7. I have used the online editor too.

Any word on this? Happy to help if I can.

It seems the version of include files we use are too old (https://github.com/supercollider/supercollider/tree/develop/include). Updating them on my local machine and recompiling some UGen with faust2supercollider now works (that is: without having to update the faust2supercollider tool or SC architectures files). So @orlarey I guess we'll have to update include files on the compilation service.

Should work on Faust IDE (remote compilation service has been updated).

Thank you! I'll test soon!

Confirmed that it works with the OSC example, thanks so much! @KonVas maybe you want to check, but looks sorted!
