Are you talking from a developer or users POV?
As a user, you project has an options page. Right click on Project and
select properties. Under C/C++ Build->Settings. Look under GCC C++ Compiler
(or respective compiler you are using) and select preprocessor. There is an
option here to set -D flags. This is set on a per project basis.
As a plugin developer, you can set project options on a project being
created by calling ManagedBuildManager.setOption(IConfiguration config,
IHoldsOptions holder, IOption option, String[] value)
Parameters:
config The configuration the option belongs to.
holder The holder/parent of the option.
option The option to set the value for.
value The values the option should contain after the change.
I set this option across all configurations. To modify the GCC C++ Compiler
-D option I talked about earlier, your command would call:
ManagedBuildManager.setOption(config,tools,tools.getOptionById("gnu.cpp.compiler.option.preprocessor.def","foo");
If you aren't sure the id, you can always import
org.eclipse.cdt.managedbuilder.gnu.ui and look at the buildDefinitions
extensions
