Building GDB on a freshly installed machine FAQ

So you just installed Fedora, RHEL or CentOS and now you want to build GDB from source.

How do you make sure everything you need to build it is installed?
```
# dnf builddep gdb
```
Did it say, No such command: builddep? Do this, then try again:
```
# dnf install dnf-plugins-core
```
Did it say, dnf: command not found…? You’re using yum, try this:
```
# yum-builddep gdb
```
Did it say, yum-builddep: command not found…? Do this, then try again:
```
# yum install yum-utils
```

Thank you, you’re welcome.

Python hacking

Python‘s had this handy logging module since July 2003. A lot of things use it, so if you’re trying to understand or debug some Python code then a handy snippet to insert somewhere is:

import logging
logging.basicConfig(level=1)

Those two lines cause all loggers to log everything to the console. Check out the logging.basicConfig docs to see what else you could do.
