Yes, I also had this same problem with Ubuntu 13.10 and KDevelop 4.5.1. Below, I've included both the problem and the solution.
Problem:
Ubuntu 13.10 uses GDB 7.61, which reads Python3 pretty-printer scripts, but Ubuntu 13.10 shipped with Python2 pretty-printer scripts. Oops!
Solution:
First, make sure that you have the needed “.gdbinit” file in your home folder – the one that your hyperlink references. This will inform GDB where to look for the required Python3 pretty-printer scripts. It goes without saying, you might have to update the path in “.gdbinit”. Mine, looks like this:
python
import syssys.path.insert(0, '/usr/share/kde4/apps/kdevgdb/printers')
from qt4 import register_qt4_printers
register_qt4_printers (None)from kde4 import register_kde4_printers
register_kde4_printers (None)from libstdcxx import register_libstdcxx_printers
register_libstdcxx_printers (None)end
Now, you need to use the “2to3” shell command to convert the Python2 scripts to Python3 scripts. For example:
2to3 -w /usr/share/kde4/apps/kdevgdb/printers/qt4.py
2to3 -w /usr/share/kde4/apps/kdevgdb/printers/libstdcxx.py
I didn't need to convert the kde4.py script: it was already a Python3 script.
Note: Just to be on the safe side, backup the script files before you do the conversion – you never know.
That's all there is to it, fire-up KDevelop and away you go...
Actually, you can use the gdb shell command to fire-up GDB and make sure that all of your Python scripts are version 3: if you don't get any read errors, you know you're okay. If it generates read errors, simply convert those scripts.
FYI: To get out of GDB, just enter “quit” and press the “Enter” key: (gdb) quit
Addendum:
If your system doesn't contain the libstdcxx.py file, you'll need to do the following:
In the folder that contains your other pretty-printer scripts, create a file and name it libstdcxx.py
Go to the following web page:
http://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python/libstdcxx/v6/printers.py
Now, copy the web page contents and paste it to your newly created libstdcxx.py file.
Since this file comes from gcc, it's more than likely a Python3 script - you'll have to see.
