I’m new to iPlug2. I was attracted by the ability to easily build a VST3 on top of Faust.  
I’m working on Windows 10 with Visual Studio Community 2019.

I have opened the IplugFausDSP VST3 example project and I’ve tried to run it in Debug mode to test the DSP file compiling (FAUST\_COMPILED directive undefined). I’m receiving errors for undefined symbols inside IPlugFaustGen, that should come from faustlib If 'm not wrong.

I have downloaded all the dependencies with the download scripts, and I confirm that the folders under iPlug2\Dependencies\Build\win\Faus are populated as expected.  
Why doesn’t VS resolve the symbols? I also checked that the project inherits the $(FAUST\_LIB\_PATH) macro inside the Linker dependencies.

Well the problem was the Win32 Platform 🙂  
Switching to x64 solved the problem
