Using multiple applications from single atk directory

From Achievo/ATK Wiki

The following procedure is used where multiple ATK applications are on the same domain. For multiple domains, use symbolic links (*NIX) or junctions (Windows), which is not covered here.

To make multiple atk applications share a common atk directory, there are a couple of steps to take:

1. Remove the line $config_atkroot="/." in the files: app.php, top.php, index.php, welcome.php, menu.php etc. These files include atk.inc, and the $config_atkroot will be set there.
2. Edit atk.inc:
   1. Add a $config_application_dir="./"; before include_once(...)
   2. Change $config_atkroot="../common_code/"
      This path must be relative to config_approot, and must be readable by your webserver and the users browser.

Traditional Procedure

For ATK versions before 6.2.0, use the following procedure: The following procedure is tested on atk 5.6.0 and is used where multiple atk applications are on the same domain. For multiple domains, use symbolic links (*NIX) or junctions (Windows), which is not covered here.

   2. Change $config_atkroot="../common_code/"
      This path must be relative to config_approot, and must be readable by your webserver and the users browser.
3. Edit Initial.inc (in atk/include dir) (also edit when updating to a new version of atk):
   1. Change $config_atkroot to $config_approot in include_once($config_atkroot."config.inc.php");
   2. Move same line (include_once($config_approot."config.inc.php")) before '// Auto-register modules' so it read your app modules from the right place
4. Edit config.inc.php:
   Make sure a $config_module_path = $config_appdir."modules/"; is present
5. Default you use a atktmp dir in your $config_atkroot dir.
   If your want temp files in your app path add the following to your config.inc.php:

  $config_atktempdir = $config_approot."atktmp/";
  $config_tplroot = $config_approot;
  $config_tplcompiledir = $config_atktempdir."compiled/tpl/";
  $config_tplcachedir = $config_atktempdir."tplcache/";
