Portable Projects

1 Problem

CCS4 projects store absolute paths. Moving a project to a different directory or another computer is not possible.

This example assumes the following directory structure:

CCS_projects
    |
    +--- dmodule (D.Module specific headers and linker command files)
    |
    +--- common (libs, headers, etc)
    |
    +--- utils 
    |
    +--- myprojects
    |        |
    |        +--- current_project (source files)

• create a file macros.ini in the project directory (current_project in the above example). This file must contain an entry EXT_ROOT__current_project = ../../
  EXT_ROOT__current_project now points to the project base directory (CCS_projects in the above example). To give highest compatibility even for later CCS releases, this macro should always start with a leading EXT_ROOT__ and end with the trailing project name.

• make sure all source files include header files with a relative path, or add the include path in the project settings:

 #include "../../dmodule/dm2c6747.h"

or, if the base directory CCS_projects is added to the project include options:

 #include <dmodule/dm2c6747.h>

• edit the .project file in the project directory (current_project in the above example) and replace the absolute paths with the SWROOT macro. Replace the <location> tag

 <linkedResources>
   <link>
     <name>dm2c6747.cmd</name>
     <type>1</type>
     <location>d:/work/ccs_projects/dmodule/dm2c6747.cmd</location>
   </link>
 </linkedResources>

with

     <location>EXT_ROOT__current_project/dmodule/dm2c6747.cmd</location>

• Use ${EXT_ROOT__current_project} in the Build Properties to add include paths and/or call programs for post-build steps:

 Build Properties - Tool Settings - C6000 Compiler - Include Options = ${EXT_ROOT__current_project}
 ${EXT_ROOT__current_project}/utils/makehex ${BuildArtifactFileBaseName}
