Is there a way to set preprocessor definitions for only the “standalone” “vst3” etc. build targets? ---

Did you already have a look at [A Format Only Code](https://forum.juce.com/t/a-format-only-code/32800) and [Standalone vs VST defs](https://forum.juce.com/t/standalone-vs-vst-defs/33298)? ---

Ok I have two followup questions: 1. `JUCEApplicationBase::isStandaloneApplication()` seems to be not found by my compiler? Do I need to add a specific module or include anything? 2. (only necessary if 1. cant be resolved) Where do I turn off the “shared code” option, so the defines dont get set all at once? Thanks ---

You can check during runtime if your plugin is running as a standalone with your AudioProcessor’s wrapperType member. (Check if it’s set to wrapperType\_Standalone.) ---

> [@Xenakios](#): > > with your AudioProcessor’s wrapperType member. (Check if it’s set to wrapperType\_Standalone.) wrapperType member? Please elaborate! My processor seems to have no such member and a repo wide search for “wrapper” turned out blank. ---

It’s a member of the AudioProcessor base class in Juce itself. ---

Ok that worked out! Thank you both for your answers, much appreciated! 🙂 ---

Hmmm I just found this will always be true, even in VSTs for some reason… Am I doing this right? ```auto m_is_standalone_plugin = (typeid(wrapperType) == typeid(wrapperType_Standalone)); ``` ---

Why are you using `typeid`? You should be comparing `wrapperType` with `wrapperType_Standalone` directly, i.e. ```auto wrapperType == wrapperType_Standalone ``` ---

Ok now it works. I figured the WrapperTypes would be different subclasses to wrap the plugin, not literal type identifiers 😄 Anyway thank you!
