Hi,
I haven't had any luck with the debugger aspect of Eclipse.

I have a simple pyDev module.
Is it correct for it to still be calling cdt and GdbLaunch?
I would have expected a java interpreter to be used for step-through debugging of PyDev projects.

My most recent project before this was a CDT c++ project.  I was unable to get debugging working for this as well.

Reproducible: Always

Steps to Reproduce:
1.load a pyDev or C++ project
2. for python run the project as python run
   for c++ build debug version
3. launch debugger

Moving to CDT for comment.

Sounds like an installation issue.
Do you have the org.eclipse.cdt.dsf.gdb plugin installed.

As for python, I don't think is should be using the CDT launch.
You can go to Run->Debug configurations... to see the launch that is being used by your project.  Also, there may be a python launch configuration type you can choose on the left hand side.

I installed pydev 2.4 with CDT 8.0.1 and was able to debug both pydev projects and CDT projects. I also tried Adding CDT nature to a pydev project and I was able to debug both the python module and the executable. I think this is an installation issue.

Two people now feel this is a configuration issue.  If there is no feedback from the person that opened the bug by mid-next week, let's close as WORKSFORME

No response, assuming it was an installation issue.
