let me know if i can help to fix this...

I'm on Ubuntu 20 LTS (updated) and I try to reproduce. If I can't maybe we should set you up to compile in debug and we can find the problem?

EDIT same version of SC, I cannot reproduce...

[chriskiefer]

i tried 1.0.2 and still get the same issue. I'll see if i can compile and find the problem - what's a good approach to debugging flucoma in sc plugins?

[chriskiefer]

i've found a workaround - compiling the latest SuperCollider 3.14.0-dev from source fixes the issue, and works fine with 1.0.2 and 1.0.7 - so it sounds like it could be an issue with the SC 3.13 ubuntu package rather than flucoma

[tremblap]

I usually link the debugger to scsynth (llvm via xcode) and compile as debug - that way we can trace where the problem emerges very precisely. It is strange that 3.13.0 works in that version of ubuntu for me - so maybe it is an os+sc version mismatch?

[tremblap]

@chriskiefer did you sort this? do you have a bug report?

[chriskiefer]

not yet i'm afraid

This is quite possibly down to SC's change in boost version, and the code crime we currently commit that requires flucoma to be built against the same boost as SC. (Hopefully the need for this will go in due course). Our CI is currently just pulling the latest SC to build against. Possibly we'll to manage this transition by temporarily having builds for both.

Anyway, if this is working for you now, can I close?
