Moin Debug with Winpdb

In case of difficult errors (traceback) you need a powerful tool to debug - Winpdb

Install WxPython for Mac

Get the WxPython binary for Mac OS X from wxPython2.9-osx-

Because of a problem with Mountain Lion Gatekeeper to have to use a workaround to install WxPython, see here.

# Double click on the .dmg install file.
# Drag the .pkg file to your work folder

# cd to the folder of the .pkg file

$ sudo installer -pkg wxPython2.9-osx-cocoa-py2.7.pkg -target /
installer: Package name is wxPython2.9-osx-cocoa-py2.7
installer: Installing at base path /
2012-10-04 20:13:25.783 installer[1850:5903] Package /Users/rudi/Install/Utils/wxPython2.9-osx-cocoa-py2.7.pkg uses a deprecated pre-10.2 format (or uses a newer format but is invalid).
installer: The install was successful.

Prepare target for debug

In order to allow debugging per GUI you have to insert into your Python program:

    import rpdb2; rpdb2.start_embedded_debugger('123', fAllowRemote=True)

Winpdb GUI local/remote

The call on the command line (terminal) shows up a window for local debug:

$ ./winpdb

If you want to remote debug your program you have to call:

$ ./winpdb  -–host=
