Description Oyvind Harboe

2011-05-27 02:51:44 EDT

Build Identifier: 20110218-0911

I've got a C++ project 27000 files and 4million lines of code and having C++ indexing would be helpful to find my way.

The project is built with scons from the command line using all sorts of nasty manual tricks to make it build reasonably quickly, so I don't want Eclipse to try to build the project for me. Just edit + debug.

When importing the C++ project, I get an NPE.


First NPE and possibly followup errors:

Reproducible: Always

Which version of CDT are you using (the stack trace does not match the sources)?
How are you running CDT, I have never seen a IncompatibleClassChangeError before and it has to do with how you run your application.

I'm launching it from an icon shortcut to eclipse.exe on the desktop. I
modified the .ini file to have 2048mByte heap

Comment 3 Markus Schorn

In CDT 7.0.2, I find the return-statment 'return true;' on line 185 of CPPASTDeclarator.java. Also, the IncompatibleClassChangeError cannot be caused by CDT itself.

Please double check your installation.
