| # First build the python package with DEBUG, and then install the resulting python-gdb.py script into a place where gdb will find it. | |
| /usr/ports/lang/python27 # make config OPTIONS_FILE_SET=DEBUG | |
| /usr/ports/lang/python27 # find . -name python-gdb.py | |
| ./work/Python-2.7.8/python-gdb.py | |
| cp ./work/Python-2.7.8/python-gdb.py \ | |
| /usr/local/bin/python2.7-gdb.py | |
| # Now install gdb with python support: | |
| /usr/ports/devel/gdb # make config OPTIONS_FILE_SET=PYTHON | |
| # Then run your script: | |
| gdb78 --args /usr/local/bin/python ~alfred/t.py | |
