Help setting CDT Indexer include path programmatically [message #821762]

Hi,
I am new to developing using CDT plug-in. I am currently using Eclipse Indigo to develop my plug-in. I was planning on making use of the features automatically available with CDT - content assist, error reporting, etc. But CDT always reports syntax errors - "Type '<Variable>' could not be resolved" and annotates the source for all definitions and variables unless they are defined in the same source file. This makes code readability very difficult. The project build successfully as it has its own build files where the Include path is correctly referenced..

I presume that this is due to the CDT indexer not having all the include paths available to it. I want to know how I can provide CDT with the include paths programmatically. It is not possible to provide the include paths via preferences as there are a lot of modules and they change across projects.

I looked online for a way to programmatically set the include path but I was not able to find any help or instructions. Any help with this will be appreciated.

With Regards,

Presanna Raman.

P.S. I have attached image of what I see in the editor. Note: The INT32 macro is resolved while the rest are not.

I further searched online and found code similar to the following. But it does not seem to help me with setting the project Include path.

		ICProjectDescription projectDescription = CoreModel.getDefault().getProjectDescription(project);
	        ICConfigurationDescription activeConfiguration = projectDescription.getActiveConfiguration();
	        ICFolderDescription folderDescription = activeConfiguration.getRootFolderDescription();
	        ICLanguageSetting[] languageSettings = folderDescription.getLanguageSettings();
	        
	        int id = 0;
	        for(int i=0; i<languageSettings.length; i++) {
	            String langId = languageSettings[i].getLanguageId();
	            if(langId.contains("org.eclipse.cdt.core.gcc")) {
	                id = i;
	                break;
	            }
	        }
	        ICLanguageSetting lang = languageSettings[id]; 
	        		//lang.setSettingEntries(ICSettingEntry.INCLUDE_PATH, enryList)
	        lang.setSettingEntries(ICSettingEntry.INCLUDE_PATH, lse);
	        projectDescription.setActiveConfiguration(activeConfiguration);
	        projectDescription.setCdtProjectCreated();
	        CoreModel.getDefault().getProjectDescriptionManager().setProjectDescription(project, projectDescription);

What I am doing wrong? I tried to find what each of these classes mean but I am having difficulty finding helpful documentation.

With Regards,

Presanna Raman.

Hi Raman,

I have a similar issue with my plugin.
After a search in the CDT sources I found something that is working for me in:
Project: org.eclipse.cdt.ui
Class: org.eclipse.cdt.internal.ui.wizards.settingswizards#readSettings()

This is finally how I made it:

IProject project = ...
ICProjectDescription projectDescription = CoreModel.getDefault().getProjectDescription(project, true);
ICConfigurationDescription configDecriptions[] = projectDescription.getConfigurations();
for (ICConfigurationDescription configDescription : configDecriptions) {
	ICFolderDescription projectRoot = configDescription.getRootFolderDescription();
	ICLanguageSetting[] settings = projectRoot.getLanguageSettings();
	for (ICLanguageSetting setting : settings) {
		if (!"org.eclipse.cdt.core.g++".equals(setting.getLanguageId()))
			continue;
		List<ICLanguageSettingEntry> includes = new ArrayList<ICLanguageSettingEntry>();
		includes.addAll(setting.getSettingEntriesList(ICSettingEntry.INCLUDE_PATH));
		includes.add(new CIncludePathEntry("/my/local/include/path", ICSettingEntry.LOCAL));
		setting.setSettingEntries(ICSettingEntry.INCLUDE_PATH, includes);
	}
}
CoreModel.getDefault().setProjectDescription(project, projectDescription);

I am also developing a eclipse plugin to write include paths programmatically. I used the above code.
But the C/C++Build->Paths&Symbols does not update with the new data.

When access the data using setting.getsettingEntries() I can see the newly added data. But can't see in the properties window or
in project explorer.

Hi TBT Andrew,

I made a mistake in the code above - bad if (...)
This is how I made it finally:
if (!setting.getId().startsWith("cdt.managedbuild.tool.gnu.cpp.compiler"))
continue;

Hi Slavian Petrov,

I am developing an eclipse plugin. I want to add the include paths programmatically when creating a new project. I am not sure about where to include the piece of code mentioned in the above posts. Could you please let me know the point where should this code be initiated.

Regards,
Krishnaraj.

Hi Raman,

Could you please let me know where should I write the piece of code mentioned by you so that new projects created will include the "INCLUDE PATHS".

Regards,
Krishnaraj.
