[cdt-dev] Macros set in external settings provider not visible.

["Waterlander, Erwin" <erwin.waterlander@xxxxxxxxx>]

Hi,

I added an External Settings Provider to the CDT-plugin developers guide example. In the provider I add an include path and a macro. In the project properties " C/C++ General > Paths and Symbols" I can see the include but not the macro. The Symbols tab is not there at all. What do I need to add to get the macro visible?

plugin.xml:

   <extension
         id="org.eclipse.cdt.example.toolchain.externalprovider"
         name="Example external provider"
         point="org.eclipse.cdt.core.externalSettingsProvider">
      <provider
            class="org.eclipse.cdt.example.toolchain.MyExternalSettingProvider">
      </provider>
   </extension>


provider class:

public class MyExternalSettingProvider extends CExternalSettingProvider {

    public MyExternalSettingProvider() {
        super();
    }

    @Override
    public CExternalSetting[] getSettings(IProject project, ICConfigurationDescription cfg) {

        List<ICSettingEntry> entries;
        entries = new ArrayList<ICSettingEntry>();

        ICLanguageSettingEntry entry;
        entry = CDataUtil.createCIncludePathEntry("${HOME}/include2", ICSettingEntry.NONE);
        entries.add(entry);

        entry = CDataUtil.createCMacroEntry("EXTERNAL", "erwin", ICSettingEntry.NONE);
        entries.add(entry);

        List<CExternalSetting> settings = new ArrayList<CExternalSetting>();
        CExternalSetting externalSetting = new CExternalSetting(new String[] { "org.eclipse.cdt.core.gcc" }, null, null,
                entries.toArray(new ICSettingEntry[0]));
        settings.add(externalSetting);

        return settings.toArray(new CExternalSetting[0]);
    }

}

Adding the provider:

    public void addExternalProvider(IProject project, ICProjectDescription projectDescription,
            ICConfigurationDescription cfgDescription) throws CoreException {

        // Get existing list of external providers of the configuration.
        List<String> extProviderIds = new ArrayList<String>();
        String[] ids = cfgDescription.getExternalSettingsProviderIds();
        for (String id : ids) {
            extProviderIds.add(id);
        }
        // Add new external provider
        extProviderIds.add("org.eclipse.cdt.example.toolchain.externalprovider");
        cfgDescription.setExternalSettingsProviderIds(extProviderIds.toArray(new String[0]));

        CoreModel.getDefault().setProjectDescription(project, projectDescription);
        System.out.println("Added external provider.");
    }
