Debugging a Python Extension in Eclipse

I have a Python extension that I have successfully built and used on Windows, OSX, and linux. I now need to be able to debug this Python extension. I am averse to the use of gdb at the command line, so I would really like to get this to work in Eclipse.

To begin with, I did my best to follow the instructions in http://www.heikkitoivonen.net/blog/2008/07/21/debugging-python-extension-written-in-c-with-eclipse/, and I added the folder for the Python source as well as the folder for the python extension code开发者_Python百科 as source folders to the empty project. Since it is relatively easy to get debug builds of everything required on linux, I started out with the debug development in Ubuntu.

Once I got a debug build of python (lets call it python_d), I ran the setup.py for my extension with

python_d setup.py build

which should also yield a debug build of the extension module. I have verified that symbols are being exported by opening the extension as an application in Eclipse and I can see the source code linked with the Python shared object.

Now if I create another project in Eclipse with the folder of my code, and add a breakpoint in the source that is used to create the extension, it doesn't stop at the breakpoint. It is entirely possible that I am missing something rather critical here, but for the life of me I can't get it to work. The crux of the problem is:

How can you get Eclipse to stop at a breakpoint in a Python extension module?

Which compiler are you using, MSVC or GCC? For MSVC, you can start python first, and attach the python_d.exe (windbg or visual studio), then you can load your module, setup the breakpoint, you can verify whether your module's symbol got loaded in the debug->module windows (MSVC).
