Slate - "undeclared identifier" on cmpilation only

Hello, I am following the Slate Hello tutorial but am running into a little trouble.

In particular, I get the “undeclared identifier” error upon compiling in the line

	TSharedPtr<SMyTextBoxWidget> myWidget;

belonging to my HUD class but I have included SMyTextBoxWidget.h, syntax coloring works too, and intellisense doesn’t underline anything. The other error I receive says that SMyTextBoxWidget is not a valid object to pass to the template, but I’m guessing it’s because the class isn’t recognized in the first place.

I earlier had managed to place a Slate button on the screen directly through another class, so I believe the project is set up to include any references (those stuff in the .cs file anyway) and it should work.

I created the class through the editor and set it to the first of the two options for being a child of a slate object, and I believe I fully reverted the code to the one generated:

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once


#include "Widgets/SCompoundWidget.h"
#include "MainHUD.h"
#include "SlateBasics.h"

/**
 * 
 */
class MYPROJECT_API SMyTextBoxWidget : public SCompoundWidget
{
public:
	SLATE_BEGIN_ARGS(SMyTextBoxWidget)
	{}
		//SLATE_ARGUMENT(TWeakObjectPtr<class AMainHUD>, OwnerHUD)
	
	SLATE_END_ARGS()

	/** Constructs this widget with InArgs */
	void Construct(const FArguments& InArgs);
};

Thanks in advance.

Edit: my slate-inheriting class doesn’t show up in the content browser either, not sure if it’s of any relevance.

It turns out the reason it appears only on compilation is that it is circular dependency between the files, I had the HUD included in the slate, and the slate in the HUD. The solution, as is visible in the tutorial listed, is to declare the slate class in the HUD’s file, as would be done with an external variable.
