[cdt-dev] Project Environment Not Being Updated

["Karol Krizka" <kkrizka@xxxxxxxxx>]

Hi all,

I'm trying to modify the environment variables of a custom projectType
that I created. I set the projectEnvironmentSupplier variable to a
class that extends the IProjectEnvironmentVariableSupplier interface
and I think I implemented it correctly. The getVariables() function
does get called when I create a projectType or start a new eclipse
session (once for each project), but I cannot see any of the custom
variables under Project Icon -> Properties -> C/C++ Build ->
Environment.

Also I have another related question. If I launch a new system program
using ProcessFactory.getFactory().exec(), does it use the environment
of the project?

Cheers,
Karol Krizka

//Find the environment, used later in CMTEnvironment
	public EnvVar[] getEnvironment()
	{
		String[] env=sh.environment();
		EnvVar[] ret=new EnvVar[env.length];
		//Convert from Java format to CDT format
		for(int i=0;i<env.length;i++)
		{
			String[] set=env[i].split("=",2);
			ret[i]=new EnvVar(set[0],set[1]);			
		}
		return ret;
	}


public class CMTEnvironment implements IProjectEnvironmentVariableSupplier {
	private CMTHome ch;
	
	public CMTEnvironment()

	public IBuildEnvironmentVariable getVariable(String variableName,
			IManagedProject project, IEnvironmentVariableProvider provider) {
		EnvVar[] vars=ch.getEnvironment();
		for(int i=0;i<vars.length;i++)
			if(vars[i].getName()==variableName) return vars[i];
			
		return null;
	}

	public IBuildEnvironmentVariable[] getVariables(IManagedProject project,
			IEnvironmentVariableProvider provider)
	{
		System.out.println("Provide!");
		return ch.getEnvironment();
	}
