[cdt-dev] How to manage one option from one holder(tool) by another opti

[Khaled ABDA <khaled.abda@xxxxxx>]

Thank you Wieant

In fact you gave me the clue to make more investigation to resolve my
problem.
I went in your way at the beginning but I found no solution,
That is why I used the original Option.
But with your clue and after reflection and more investigation
I found that I was confusing between CDT 3.0 and CDT 4.0.
In fact I shifted to the CDT 4.0 AND with this later version
THE "IBuildObject configuration" IS NO MORE "instanceOf" of either
"Iconfiguration" or "IResourceConfiguration" BUT OF "IFolderInfo".
(it is already mentioned in the CDT 4.0 architecture 
 but had not payed attention)
Once we detect that, we manage ALL resources in "Tool settings".
Here is the source I implemented to manage my options, 
it might be usefull for Others.
---------------------------------------------
public boolean isOptionEnabled(IBuildObject configuration,
			IHoldsOptions holder, IOption option) {
		 try {
			if (configuration instanceof IFolderInfo) {
				IFolderInfo folderInfo = (IFolderInfo)
configuration;
				IOption[] MlibOpt = folderInfo.getParent()
	
.getTargetTool().getOptions();
				for (int i = 0; i < MlibOpt.length; i++) {
					//here I use the "startsWith" to use
the original option
					//if it's not yet used or the
dynamic options once it's used
					if
(MlibOpt[i].getBaseId().startsWith(
							"myOptionId")) {
	
ManagedBuildManager.setOption(folderInfo
							.getParent(),
folderInfo.getParent()
							.getTargetTool(),
MlibOpt[i],
option.getBooleanValue());			
					}
				}
			}
		} catch (BuildException e) {
			e.printStackTrace();
		}
	Return true;
}

The problem might be that when you are in the properties dialog you
are working with a copy of the original project settings. Only when
you press 'Apply' or 'Ok' these working copy settings are transfered
to the actual '.cproject' project settings. So using

  IOption MlibOpt =
ManagedBuildManager.getProjectType("stxp.target.sx.w32.exe").getConfiguratio
n("...").getTool("...").getOptionBySuperClassId("...");

will get you the original project option, not the actual working
copy. To get the latter I think you should use the 'IBuildObject
configuration' parameter passed to 'isOptionEnabled()'. From that
value you can get the IConfiguration value which in turn can be used
to get the linker tool, and using ITool.getOptions() to get
the dynamic options (the ones with the random number, if changed).
