Colin and others already posted simillar things.
I get a null pointer exception on QNX/none - C/C++ project creation.
This only happens when I have switch my enviornment to use 6.4.0 build configs, when I use environment for 6.3.2 
everything works fine.
The settings for 6.4.0 are correct - I can work using cmd line.
I don't see a solution for this problem in the other threads.
Even when I start with a new/empty eclipse configuration folder, I get an indexer error message on startup.
>  An internal error occurred during: "Initialize Indexing".
>  java.lang.NullPointerException"

find attached my .log file
if you need the eclipse config folder give me a ping

thanks
