Configuration Scripts

The configuration script may tell the CST to add certain features to the Cactus environment -- either to the make system or to header files included by thorns. It does this by outputting lines to its standard output:

• BEGIN DEFINE
  <text>
  END DEFINE
  

  Places a set of definitions in a header file which will be included by all thorns using this capability (either through an OPTIONAL or REQUIRES entry in their configuration.ccl files).

• INCLUDE_DIRECTORY  <directory>
  

  Adds a directory to the include path used for compiling files in thorns using this capability.

• BEGIN MAKE_DEFINITION
  <text>
  END MAKE_DEFINITION
  

  Adds a makefile definition into the compilation of all thorns using this capability.

• BEGIN MAKE_DEPENDENCY
  <text>
  END MAKE_DEPENDENCY
  

  Adds makefile dependency information into the compilation of all thorns using this capability.

• LIBRARY <library>
  

  Adds a library to the final cactus link.

• LIBRARY_DIRECTORY <library>
  

  Adds a directory to the list of directories searched for libraries at link time.

No other lines should be output by the script.
