Now this produces output in the console window.

The indexer complains a lot about not being able to apply constants declared in enum declarations.
I see it includes a lot of files right up to the point where it includes my problem file. It just stops with no further output to the console window. It looks like I definitely will have to get out the debugger.

Thanks for the info Markus.

Hi Ray,
If the IDE hangs it is always a good idea to create stack-traces.
* That is easy on a unix system, use:  kill -QUIT process_id.
* Another way (that works on Windwos also) is by using Sun's JDK 1.5:
  Run the IDE with the JVM option -Dcom.sun.management.jmxremote, then
  you can use the jconsole (part of JDK 1.5) to connect to the hanging
  IDE and inspect the current stack traces.

The options for tracing the indexing have been refined
(see https://bugs.eclipse.org/bugs/show_bug.cgi?id=155324), you can use
  # Reports sequence of files indexed
  org.eclipse.cdt.core/debug/indexer/activity=true

  # Reports statistics for indexer
  org.eclipse.cdt.core/debug/indexer/statistics=true

  # Reports problems for indexer
  org.eclipse.cdt.core/debug/indexer/problems=true

Markus.

Subject: [cdt-dev] Need to know how to debug the indexer

It seems that there was a discussion a while back on how to debug the indxer and adding some code to support a logging function. Did anything happen?

I have a project with 400+ files and the indexer always hangs on a particular file. I typed on the command line "gcc - E -P -v -dD include-dirs file.c" and an output is generated with no errors. How do I determine what the indexer is doing?

How do I go about debugging this?
   My System
   Windows XP
   Eclispe SDK 3.3M4
   CDT SDK 4.0.0M4

What I have tried:
   Created a .options file containing the following:
     org.eclipse.cdt.core/debug/pdomtimings=true
     org.eclipse.cdt.core/debug/indexer=true
     org.eclipse.cdt.core/debug/parser=true
     org.eclipse.cdt.core/debug/deltaprocessor=true
     org.eclipse.cdt.core/debug/scanner=true
     org.eclipse.cdt.core/debug/model=true

I executed the following command
   eclipse -debug .options

The results:
An extra DOS console window opened up and printed several diagnostic messages up to the point of loading the project. Nothing else printed afterwards. Nothing printed during the Rebuild Index operation.

Do I need to add the entire CDT as a project and run it in debug mode?

OK. I tried using the debugger and failed miserably.
I need to know where it all starts so I can step through it.
I need to know how the indexer keeps track of files, PDOM data, etc.
I also need to know what parser is used has the parser is report parser errors but the info is not specific enough. Like when a data structure is flagged as an error condition which member fo the data structure is suspect.
I can tell that this entails a great deal fo code.
