You can see
here<https://github.com/rubenvb/MinGW-w64-build-scripts/blob/master/toolchain/scripts/python.sh>what's
needed for Python GDB. My
builds<http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/release>come
with python-enabled gdb too. Only the python27.dll and the lib/
directory inside "bin" is necessary for correct Qt and Qt Creator
functionality.
