Adding Include paths and symbols
For CDT projects you can define include paths and
preprocessor symbols for the parser. This enables the parser to
understand the contents of the C/C++ source code so that you may more
effectively use the search and code completion features.
If Autodiscovery is enabled once a build has completed any
discovered paths and symbols will be displayed in the Discoverd Paths
section. You can also define the properties on a per project basis in
the C/C++ Projects or Navigator views.
To add include paths and symbols:
- To set properties for your project right click your CDT
project and select Properties. Alternatively, to set properties
for a specific source file in your project right click a source file
within your standard make project and select Properties.
- Click C/C++ Include Paths and Symbols.

- Use "Add" button to define new element (Include Path, Symbol, Library path etc).
- Use "Edit" button to change selected element (Include Path, Symbol, Library path etc).
- Use "Delete" button to remove selected element (Include Path, Symbol, Library path etc).
- Use "Export" button to make selected element (Include Path, Symbol, Library path etc) exported.
- Use "Unexport" button to remove selected element (Include Path, Symbol, Library path etc) from export list.
- Use "Move up" and "Move down" buttons to set elements (Include Paths, Library paths etc) order.
