The commits I've seen after 7.0.10 don't seem to tackle anything related to C++23, but also I haven't tried building again using C++23 since then. Did you also get a failure @tarlanahad ?
Thanks we're aware of the issue but we're working on JUCE 8 first. Unfortunately to fix builds for C++23 we'll need to make changes in areas that have been heavily modified in JUCE 8 which is why we haven't tackled this yet.
Sorry for any inconvenience caused and thanks for your patience.
@lkotsonis , yes, I'm getting failure mainly because of not fully defined unique_ptr, which C++ 23 strictly requires.
I hope you can solve this, @Anthony-Nicholls , we will be looking forward to using JUCE with C++ 23. Thanks for the prompt response.
