VST3 build target just won't build

[sancho1980]

I am trying to build a VST3 plugin from my JUCE project.
I have set the path to the VST3 SDK accordingly under File->Preferences.
When I check “Build VST” and run make, a .so file is generated as expected.
Also checking “Build VST3” seems to make no difference at all - all that is built is the VST2 target (.so file).
When I uncheck “Build VST” and leave “Build VST3” checked, running make produces:

$ make
make: Nothing to be done for ‘all’.

Strangely enough, building the VST2 target even works when I enter an erroneous VST path under File->Preferences.

How can I build a VST3 plugin?

Build configuration is Linux Makefile.

We don’t use the VST2 part of the SDK - that bit is all handled by custom JUCE code.

Linux VST3 support is not currently available, but it is on our roadmap:

Linux X11 windowing in a VST 3.6.7 plugin using JUCE components

Hi, I’m making a VST3 plugin on Linux with the new release 3.6.7. I’m trying to make it work with the Steinberg “editorHost”. For the GUI I’d like to use JUCE components instead of Steinberg’s VSTGUI. So I’ve defined a class “JUCEView” which inherits both from Steinberg’s EditorView and JUCE’s Component classes. To enable JUCE component attachment, I’ve overridden methods, especially the “attached” one : > virtual Steinberg::tresult PLUGIN_API attached(void* parent, Steinberg::FIDString type)…
