Hi, i am working on a Wavetable Synthesizer, only worked in a sub class, but im getting the compile error “Call to deleted constructor of ‘WavetablePlugInAudioProcessor’” and “Unknown type name ‘WavetablePlugInAudioProcessorEditor’; did you mean ‘WavetablePlugInAudioProcessor’?” in the processor line:

````
```juce::AudioProcessorEditor* WavetablePlugInAudioProcessor::createEditor(){
return new WavetablePlugInAudioProcessorEditor (*this);
} ```

````

That confuses me, i didn’t changed anything of this function. What is to do to fix this?

Thanks

The deleted constructor error is usually associated with the smart pointers. Are you moving your Editor so it is not a sub class of the Processor?

It would be good to see the exact error message, including where the error occurred.  
While it is a common mistake to accidently copy things that have the copy constructor intentionally deleted, there are other mistakes that show similar errors.

What does it mean to ‘copy things that have the copy constructor intentionally deleted’? Sorry i’m quite new to Juce and C++ and learn both simultaneously.

The copy constructor is a red herring. It doesn’t know your Editor by the type of `WavetablePlugInAudioProcessorEditor`. It seems you simply forgot/removed the include to the class declaration, usually called like this in the PluginProcessor.cpp:

```auto
#include "PluginEditor.h"

```

or similar, check the actual name in your project.

Yes thanks, i dont have a clue how i deleted that accidentally^^

Now i am getting:

“No matching constructor for initialization of ‘WavetablePlugInAudioProcessorEditor’”

in the same line,

“1. Candidate constructor not viable: no known conversion from ‘WavetablePlugInAudioProcessor’ to ‘const WavetablePlugInAudioProcessorEditor’ for 1st argument”

in the last line of the editor (JUCE\_DECLARE\_NON\_COPYABLE…) and

“2. Candidate constructor not viable: requires 2 arguments, but 1 was provided”

in the constructor line of the editor.h file, wich is:  
` WavetablePlugInAudioProcessorEditor (WavetablePlugInAudioProcessor&, WavetableSound&);`

It seems to me that i have to declare a pointer to my subclass WavetableSound in

```auto
juce::AudioProcessorEditor* WavetablePlugInAudioProcessor::createEditor()
{
    return new WavetablePlugInAudioProcessorEditor (*this);
}

```

because the editor changes variables in the subclass. Am i right and if so how do i do that?

Yes, you added a second parameter (argument) to your constructor, that you have to supply.  
Assuming you have a member in your processor you have to supply it to the constructor:

```auto
// member:
WavetableSound sound;

juce::AudioProcessorEditor* WavetablePlugInAudioProcessor::createEditor()
{
    return new WavetablePlugInAudioProcessorEditor (*this, sound);
}

```
