Hi, I just downloaded IPlug2 from GitHub recently and tried to compile it with MSVS 19 under Win10. The included example for IPlugInstrument does not compile for VST2 and produces following errors: 1\>C:\iPlug2\IPlug\IPlug\_include\_in\_plug\_src.h(76,36): error C2672: ‘std::max’: no matching overloaded function found 1\>C:\iPlug2\IPlug\IPlug\_include\_in\_plug\_src.h(76,62): error C2780: ‘\_Ty std::max(std::initializer\_list\<\_Elem\>)’: expects 1 arguments - 2 provided 1\>C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\VC\Tools\MSVC\14.27.28919\include\utility(52): message : see declaration of ‘std::max’ 1\>C:\iPlug2\IPlug\IPlug\_include\_in\_plug\_src.h(76,62): error C2784: ‘\_Ty std::max(std::initializer\_list\<\_Elem\>,\_Pr)’: could not deduce template argument for ‘std::initializer\_list\<\_Elem\>’ from ‘VstInt32’ 1\>C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\VC\Tools\MSVC\14.27.28919\include\utility(49): message : see declaration of ‘std::max’ 1\>C:\iPlug2\IPlug\IPlug\_include\_in\_plug\_src.h(76,62): error C2782: ‘const \_Ty &std::max(const \_Ty &,const \_Ty &) noexcept()’: template parameter ‘\_Ty’ is ambiguous What I did wrong? For VST3 it can not find included files (too many to list). Thanks ---

Not sure why you are getting the min max problem. Just made a new tutorial, if you follow the steps here, do you still get issues? > **[iPlug2/iPlug2](https://github.com/iPlug2/iPlug2/wiki/02_Getting_started_windows)** > > C++ Audio Plug-in Framework for desktop, mobile and web \[PRE-RELEASE\] - iPlug2/iPlug2 ---

New tutorial is great. It builds VST3 plugin. But if I go to VST2 project then I got the same errors in compilation 1\>C:\iPlug2\IPlug\IPlug\_include\_in\_plug\_src.h(76,36): error C2672: ‘std::max’: no matching overloaded function found 1\>C:\iPlug2\IPlug\IPlug\_include\_in\_plug\_src.h(76,62): error C2780: ‘\_Ty std::max(std::initializer\_list\<\_Elem\>)’: expects 1 arguments - 2 provided pointing me out to this line in IPlug\_include\_in\_plug\_src.h aEffect.numPrograms = std::max(aEffect.numPrograms, 1); // some hosts don’t like 0 presets ---

> [@Alex](#): > > IPlug\_include\_in\_plug\_src.h Have you modified the source code at all? I am able to compile VST2 without this min max error. perhaps you could try putting ```auto #undef min #undef max ``` before #include “IPlug\_include\_in\_plug\_src.h” in the plugin .cpp file to see if that makes a difference ---

Thanks.It builds only if I put directly aEffect.numPrograms = 0;// in “IPlug\_include\_in\_plug\_src.h” It producess .dll but fails further to run bat: CALL “C:\iPlug2\Examples\IPlugInstrument\scripts\postbuild-win.bat” “.dll” “IPlugInstrument” “Win32” “1” “C:\iPlug2\Examples\IPlugInstrument\build-win\vst2\Win32\Debug\IPlugInstrument.dll” “C:\Program Files (x86)\VstPlugins” “C:\Program Files\VstPlugins” “C:\Program Files (x86)\Common Files\VST3” “C:\Program Files\Common Files\VST3” “C:\Program Files (x86)\Common Files\Avid\Audio\Plug-Ins” “C:\Program Files\Common Files\Avid\Audio\Plug-Ins” “C:\iPlug2\Examples\IPlugInstrument\build-win” “C:\iPlug2\Examples\IPlugInstrument\projects…\Dependencies\IPlug\VST3\_SDK\doc\artwork\VST\_Logo\_Steinberg.ico” “C:\iPlug2\Examples\IPlugInstrument\projects…\Dependencies\IPlug\AAX\_SDK\Utilities\PlugIn.ico” “C:\iPlug2\Examples\IPlugInstrument\projects…\Scripts\create\_bundle.bat” ---

You need to make sure your VST2 plugins folder is set correctly in common-win.props, and that you have write permissions ---

Ok, thanks… Otherwise, it is great ! I will check the compilation on MAC tonight. Now it seems that anyone can do his own synth - a dream comes true) A good thing and is not only.
