Hello,

After creating a new Hello World C++ Project and running the executable,
The following error appears in the Error Log:

Error logged from Debug Core:

java.io.IOException: read error

I'm using CDT 4.0.3, g++ 3.3, Eclipse 3.3.2 on Ubuntu 8.04.

Any ideas?

I have a rather similar problem. A simple C-Program has a routine that
uses a text-file for output. When I try to run this program from within
Eclipse, I get the error message:

An internal error occured during: "Launching printmsg"
java.lang.NullPointer.Exception

The same when I start a debugging session. But launching the program
manually - outside eclipse - works fine.

Then I comment the code out in that routine that performs file-io. Now its
a dummy routine which does nothing. But I left all imports unchanged. No
NullPoint.Exception any more!

My System: Debian etch, Eclipse 3.3.2, CDT 4.03, Java jre1.6.0_03
