Hi all, Just a heads up: Steinberg released a new version of their VST3 SDK. Unfortunately they seem to have removed a file that is required by JUCE. MSVC gives the following error: \modules\juce\_audio\_processors\format\_types\juce\_vst3headers.h(88): fatal error C1083: Cannot open include file: ‘base/source/fatomic.cpp’: No such file or directory (compiling source file …\JuceLibraryCode\juce\_audio\_plugin\_client\_VST3.cpp) The file fatomic.cpp was present in VST 3 SDK v3.6.6 but seems to be removed in V3.6.7… ---

Thank you for reporting. The new VST3 SDK is almost completely different, and supporting it in JUCE (and getting it properly tested) is too big a job to do before the release of JUCE 5. One highlight of the new release: “this maintenance release is mainly a preview version for Linux support” but I’ve not found any more information about what “preview” means in this context… ---

Is there anywhere to get 3.6.5, then? ---

Hmm the v3.6.6 SDK seems to have been removed from the Steinberg developer page, and only v3.6.7 is available for download (last week when I checked they had both options up, but it seems Steinberg is pushing everyone onto 3.6.7 then?) ---

JUCE team, if you’re going to go with “not fixing it for now” you should try to work something out with Steinberg to allow redistributing the JUCE-compatible version until you can fix it. Steinberg is not distributing 3.6.6 anymore, and I would host it for others myself but the VST3 license agreement specifically prohibits doing so. Until then VST building for JUCE is unusable for all new users. **(!!!)** Obviously this is a huge problem and I’m surprised it’s not a top priority. Also, 3.6.7 (and presumably all future releases) are now available on Github - perhaps it would make sense to include it in the JUCE repo as a submodule in the future? Similar to the CoreAudio SDK integration, it would allow Projucer to get rid of the “VST SDK Path” field in the global settings. > **[steinbergmedia/vst3sdk](https://github.com/steinbergmedia/vst3sdk)** > > vst3sdk - VST 3 Plug-In SDK EDIT: Checked a prior version of the developer page via wayback machine, Steinberg’s 3.6.6 link is still live. But who knows when they’ll take it down: [http://www.steinberg.net/sdk\_downloads/vstsdk366\_27\_06\_2016\_build\_61.zip](http://www.steinberg.net/sdk_downloads/vstsdk366_27_06_2016_build_61.zip) ---

There is also the SDK v3.6.5 here if anybody needs it [https://sdk.steinberg.net/viewtopic.php?t=211](https://sdk.steinberg.net/viewtopic.php?t=211) but it looks like they’re not keeping many of the old versions online. ---

An update on this: we will shortly be supporting the VST3 SDK V3.6.7 exclusively. You will need to update your SDK when we make the changes. ---

OK. It’s on develop now! Linux support will come later. You will need to rebuild your projucer. ---

So to make sure I understand: (before updating…) - Latest develop branch BREAKS older VST3 SDK right? - New VST3 SDK still capable of building VST2 plug-ins? (since you’ve also removed the VST2 path from projucer). ---

- Yes, you must use the latest VST3 SDK on the develop branch tip - We don’t use any of the VST2 SDK, and haven’t done so for around 4 months - all the VST2 plugin-host interaction is handled by JUCE code ---

We just changed the behaviour slightly again: you now need to select the VST3\_SDK folder inside the VST\_SDK folder in the global preferences (or project settings), like this: ![](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/7/7e7facb6b2e3c11e80f73e7183514bab35171a68.png) Sorry for the back&forth on this. ---

In order to get my plugin to build with vstsdk 3.6.7 and the “-stdlib=libstdc++” flag for clang, I had to replace `Update::DeferedChangeListIterConst it =` in VST3\_SDK/base/source/updatehandler.cpp line 110 with: `Update::DeferedChangeList::iterator it =`
