Answer 1

If you upgrade Magento older version to Magento 2.2.3 and you fetching same error in compile then below step you should follow to resolve this error.

Magento older version have 2 directories and 2 files in this path

vendor\magento\module-backend\Model\View\Layout

1. Filter
2. Reader
3. Builder.php
4. GeneratorPool.php

And Magento version 2.2.3 have 1 directory and 2 files

1. Reader
2. Builder.php file
3. StructureManager.php

So after merge files and folder, you should delete "filter" folder and "GeneratorPool.php" from Magento version 2.2.3 on this path.

vendor/magento/module-backend/Model/View/Layout/GeneratorPool.php

then run the compile command

then no error will show.

Answer 2

Can you please confirm you have deleted the below mentioned file from your server? If not then delete it and see if it resolves the problem because this file was removed in 2.2.3 version and causes trouble when you run compile command when the file exists

vendor/magento/module-backend/Model/View/Layout/GeneratorPool.php
