IPlug2 clap branch doesn’t currently compile

1

Hi,

IPlug2 clap branch doesn’t currently compile.
(my setup: Windows 10, VS2019, everything up to date)

To make sure, I cloned a fresh IPlug2, switched to the clap branch, got all the necessary dependencies installed (CLAP_HELPERS, CLAP_SDK, and VST3_SDK for good measure).
I then duplicated IPlugEffect.
VST3 works without problems.
CLAP gives the following compiler error:

1>C:\Users\Heeb\Documents\iPlug2.x\IPlug\IPlugQueue.h(97,41): error C2440: '<function-style-cast>': cannot convert from 'initializer list' to 'T'

Switching back to a few days ago using:

git reset --hard b6a2e2fba2b7d1752e406892f23f3b8e81f7f013 --

makes it compile again, so something happened since then.

I like to stay very much up to date; is this something that’ll be fixed soon, or should I stay on b6a2e2fb… for now?

Many thanks,

Matthijs

Hi,

Just wanted to confirm that I have the same issue on MacOS (tested the same way by IPlugEffect on CLAP and VST3), and that resetting back to the commit Matthijs mentioned fixes the issue.

I’ve reverted the commit that doesn’t compile for now.

FYI: CLAP support is bleeding edge and subject to breaking changes while we get it right - proceed with caution!

Hi Oli,

Many thanks, and also many thanks for all the hard work you guys are doing on it :slight_smile:

Of course, well aware.
I like living on that bleeding edge, firstly to be able to support the CLAP standard as soon as possible (the more plugins & DAWs that support it, the better), and secondly to help iPlug2 by finding & reporting bugs, etc.

:slight_smile:

I absolutely second that!!!
