Hello everyone I’m new to juce but not to C++. I’m using the Prodjucer version 5.4.1 with XCode version 8.2.1. I’m following the JUCE tutorial and all goes fine and well until I come by the part where you display the first GUI app (which is just a Volume slider that does nothing). like shown here : [https://docs.juce.com/master/tutorial\_code\_basic\_plugin.html](https://docs.juce.com/master/tutorial_code_basic_plugin.html) I double-triple checked that my classes and methods are exactly like they are supposed to be. I didn’t forgot the addAndMakeVisible (&midiVolume). I click on the Compile & run button, all goes well, it compiles all the files and then… Nothing. No window are displayed. Anyone could explain what the \*\*\*\* (fill the blank with any 4-letter word of your choice) is happening ? Thanks a lot ! ---

The tutorial you linked is for creating a plugin, not a stand alone app. You can’t ‘run’ a plugin, it has to be loaded into an application which loads plugins (Ableton, Logic, etc). You can see that implied here at the end `Run the plug-in in the host environment` This is a tutorial in creating a stand alone app. [https://docs.juce.com/master/tutorial\_main\_component.html](https://docs.juce.com/master/tutorial_main_component.html) ---

Ok, that makes sense. Thanks a lot. Now if I want to make a plugin for DAWs that also works as a stand-alone app, like a lot of plug-ins are, it means that I have to code it as a stand-alone project and then re code it as a plug-in project ? ---

You can easily share code between projects. I’ve not done plugin work for a bit, but as it turns out, there is a mode for the plugin project that allows you to generate a stand alone (executable) version. In Visual Studio I have three projects I can select to build from ![image](https://us1.discourse-cdn.com/flex026/uploads/juce/original/2X/1/1c76356bfbdd1c58769c963e52244adc5f4705aa.png) ---

update your version of xcode while you’re at it. we’re up to xcode 10.1 now, which is pretty solid with the Legacy build system enabled.
