Configure SQLAlchemy to log all queries:
logging.getLogger('sqlalchemy.engine').setLevel(logging.DEBUG)
Configure:
./configure -prefix /home/tw55413/temp/nokia/qt_install/ -debug -opensource
Standard make:
make
make install
Prepare the build:
python build.py prepare
Configure the debugging symbols:
python configure.py -b /home/tw55413/temp/riverbank/sip_install/ -d /home/tw55413/temp/riverbank/sip_install/ -e /home/tw55413/temp/riverbank/sip_install/ -v /home/tw55413/temp/riverbank/sip_install/ --debug
Standard make:
make
make install
Configure:
export PYTHONPATH=../sip_install/
python configure.py --debug --trace -b /home/tw55413/temp/riverbank/pyqt_install/ -d /home/tw55413/temp/riverbank/pyqt_install/ -p /home/tw55413/temp/riverbank/pyqt_install -q /home/tw55413/temp/nokia/qt_install/bin/qmake --confirm-license
make
make install
set the environment variables:
export LD_LIBRARY_PATH=/home/tw55413/temp/nokia/qt_install/lib/
export PYTHONPATH=.:/home/tw55413/temp/riverbank/sip_install/:/home/tw55413/temp/riverbank/pyqt_install/
launch the python application:
python main.py
Then start Qt Creator, choose debug, and attach to the running process
For older gdb versions (pre 7), copy the gdbinit file from the python Misc folder:
cp gdbinit ~/.gdbinit
use:
ulimit -c unlimited
load core file in gdb:
gdb /usr/bin/python -c core
In newer gdb versions, Python can run inside gdb:

To give gdb python super powers:
(gdb) python
>import sys >sys.path.append(‘Python-2.7.1/Tools/gdb/libpython.py’) >import libpython >reload(libpython) > >end
