I'm trying to re-compile using

php bin/magento setup:di:compile

But when I run this command, I get:

Fatal error: Cannot use 'Void' as class name as it is reserved in /var/www/html/magento/vendor/magento/module-sales/Controller/Adminhtml/Order/Invoice/Void.php on line 9

I am running PHP 7.1.0-alpha.

I don't think Magento 2 is yet compatible with php 7.1-alpha, but this is an alarm signal.
I think you should report this on github.
It could be an issue in the near future,

Here is how to fix it:

  1. edit vendor/magento/module-sales/etc/webapi.xml line 112:

    - <route url="/V1/invoices/:id/void" method="POST">
    + <route url="/V1/invoices/:id/voidInvoice" method="POST">
    
  2. edit vendor/magento/module-sales/Block/Adminhtml/Order/Invoice/View.php line 242:

    - return $this->getUrl('sales/*/void', ['invoice_id' => $this->getInvoice()->getId()]);
    + return $this->getUrl('sales/*/voidInvoice', ['invoice_id' => $this->getInvoice()->getId()]);
    
  3. edit vendor/magento/module-sales/Block/Adminhtml/Order/Creditmemo/View.php line 183:

    - return $this->getUrl('sales/*/void', ['creditmemo_id' => $this->getCreditmemo()->getId()]);
    + return $this->getUrl('sales/*/voidCreditmemo', ['creditmemo_id' => $this->getCreditmemo()->getId()]);
    
  4. edit vendor/magento/module-sales/Controller/Adminhtml/Order/Invoice/Void.php line 9:

    - class Void extends \Magento\Sales\Controller\Adminhtml\Invoice\AbstractInvoice\View
    + class VoidInvoice extends \Magento\Sales\Controller\Adminhtml\Invoice\AbstractInvoice\View
    
  5. edit vendor/magento/module-sales/Controller/Adminhtml/Order/Creditmemo/Void.php line 10:

    - class Void extends \Magento\Backend\App\Action
    + class VoidCreditmemo extends \Magento\Backend\App\Action
    
  6. rename

    vendor/magento/module-sales/Controller/Adminhtml/Order/Creditmemo/Void.php

    to

    vendor/magento/module-sales/Controller/Adminhtml/Order/Creditmemo/VoidCreditmemo.php

  7. rename

    vendor/magento/module-sales/Controller/Adminhtml/Order/Invoice/Void.php

    to

    vendor/magento/module-sales/Controller/Adminhtml/Order/Invoice/VoidInvoice.php

  • in Magento Enterprise mv vendor/magento/module-reward/Model/Action/Creditmemo/Void.php vendor/magento/module-reward/Model/Action/Creditmemo/VoidCreditmemo.php in line 8 change class Void to class VoidCreditmemo – marcinsdance Jan 25 '18 at 11:40

This is no longer an issue for Magento 2.2 - Magento 2.1 was not PHP7.1 compatible.

Instead of modifying the core magento vendor files to resolve the issue it would make more sense to use the right php version. Depending on what you are using, it should be easy enough to set a BASH configuration for a particular php bin location.
