title: I do not get APCu installed with PHP 7.2 on my Mac
body: <p>I changed my default apache server setup on my mac to be able of easily switching between php versions following <a href="https://getgrav.org/blog/macos-sierra-apache-multiple-php-versions" rel="nofollow noreferrer">this guide</a>.</p>
  
  <p>Now, when I return to my project which is based on the CMS TYPO3, I get the error, that "The PHP extension "apcu" must be installed and loaded in order to use the APCu backend.".</p>
  
  <p>So I was following <a href="https://getgrav.org/blog/macos-sierra-apache-mysql-vhost-apc" rel="nofollow noreferrer">the tutorial (by the same author)</a> to install and enable apcu.
  I can sum up the installation process:</p>
  
  <pre><code>$ sphp 5.6
  $ brew install autoconf
  $ pecl channel-update pecl.php.net
  $ pecl install apcu-4.0.11
  </code></pre>
  
  <p>This actually worked perfectly for php 5.6! But I wanted php 7.2 for my project. The tutorial instructs to do this:</p>
  
  <pre><code>$ sphp 7.2
  $ pecl uninstall -r apcu
  $ pecl install apcu
  </code></pre>
  
  <p>No errors here. But the CMS still claims no apcu! Searching for "apc" in phpinfo also returns in no results! Pecl added the <code>extension="apcu.so"</code> line in the loaded php 7.2 ini, so I don't understand what's wrong. Of course I restarted apache every time. Also no errors or warnings here.</p>
  
  <p>Also after googling I have no idea what to do :/</p>
