C++ Why do i keep getting "inconsistent dll linkage error" on ACharacter::Jump

Here is my header file:

};

Here is my cpp file:

#include "CharachterMovement.h"

}

// Called when the game starts or when spawned
void ACharachterMovement::BeginPlay()
{
	Super::BeginPlay();
	
}

// Called every frame
void ACharachterMovement::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

// Called to bind functionality to input
void ACharachterMovement::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);
	PrimaryActorTick.bCanEverTick = true;

	PlayerInputComponent->BindAxis("Turn", this, &APawn::AddControllerYawInput);
	PlayerInputComponent->BindAxis("LookUp", this, &APawn::AddControllerPitchInput);
	if (jumpingDelay == false) {
		PlayerInputComponent->BindAction("Jump", IE_Pressed, this, &ACharacter::Jump);
	}
	PlayerInputComponent->BindAction("Jump", IE_Released, this, &ACharacter::StopJumping);
	PlayerInputComponent->BindAxis("MoveForward", this, &ACharachterMovement::MoveForward);
	PlayerInputComponent->BindAxis("MoveRight", this, &ACharachterMovement::MoveRight);
	GetCharacterMovement()->bOrientRotationToMovement = true;
}

void ACharachterMovement::MoveRight(float Axis) {
	FRotator Rotation = Controller->GetControlRotation();
	FRotator YawRotation(0.0f, Rotation.Yaw, 0.0f);
	FVector Direction = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::Y);
	AddMovementInput(Direction, Axis);

}

void ACharachterMovement::MoveForward(float Axis) {
	FRotator Rotation = Controller->GetControlRotation();
	FRotator YawRotation(0.0f, Rotation.Yaw, 0.0f);
	FVector Direction = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::X);
	AddMovementInput(Direction, Axis);

}

void ACharacter::Jump() {
	jumpingDelay = true;

}

You cannot do it this way:

void ACharacter::Jump() {
	jumpingDelay = true;

}

You have to override the method in ACharachterMovement

virtual void Jump() override;

Then in cpp:

void ACharachterMovement::Jump() {
    Super::Jump();
	jumpingDelay = true;

}

Thanks, sorry for the late reply. A few months ago I had removed windows and replaced it with Ubuntu (ue4 isnt available on Linux :frowning: ). Yesterday I bought a second hard drive so now im able get windows too in dual boot mode so iā€™m finally able to use ue4 again. Although I lost the project I was working on , I have gotten better at cpp by a lot and your reply is very logical. Thank you SolidGasStudio!
