title: Installation of Xdebug on MacOS Catalina 10.15
body: <p>I tried to install Xdebug on OS X 10.15 and run into following problem:</p>
  
  <blockquote>
    <p>/private/tmp/pear/install/xdebug/xdebug.c:25:10: fatal error: 'php.h' file not found</p>
  </blockquote>
  
  <p>I tried to fix the problem like described here: <a href="https://stackoverflow.com/questions/52623108/installing-xdebug-on-macos-mojave-php-h-file-not-found">Installing xdebug on MacOs Mojave - &#39;php.h&#39; file not found</a></p>
  
  <p>Unfortunately the header files cannot be found in this directory: <code>/Library/Developer/CommandLineTools/Packages</code></p>
  
  <p>Any ideas where I can get the current header files for OS X 10.15?</p>
