ldd is looking for

c++filt _ZN9Steinberg3Vst19WaveformViewManager9preRenderEPN6VSTGUI13CExternalViewEP10NVGcontext
Steinberg::Vst::WaveformViewManager::preRender(VSTGUI::CExternalView*, NVGcontext*)

Is he source code, I performed a grep and:

grep -r WaveformViewManager::preRender
public.sdk/samples/vst/dataexchange/source/waveformview_metal.mm:bool WaveformViewManager::preRender (VSTGUI::CExternalView* view, NVGcontext* context)
public.sdk/samples/vst/dataexchange/source/waveformview_direct3d.cpp:bool WaveformViewManager::preRender (VSTGUI::CExternalView* view, NVGcontext* context)

So, maybe a Linux implementation is missing.

The workaround I found is to remove this directory: rm -rf public.sdk/samples/vst/dataexchange/

[ygrabit]

Thanks we will remove the DataExchange for Linux due to missing implementation of the waveformView

Thanks for this answer !
