# Pretty Printer Installation
Requirements:
* icinga2 debug symbols
* boost, gcc, etc debug symbols
Install the `boost`, `python` and `icinga2` pretty printers. Absolute paths are required,
so please make sure to update the installation paths accordingly (`pwd`).
Boost Pretty Printers:
$ mkdir ~/.gdb_printers && cd ~/.gdb_printers
$ git clone https://github.com/ruediger/Boost-Pretty-Printer.git && cd Boost-Pretty-Printer
$ pwd
/home/michi/.gdb_printers/Boost-Pretty-Printer
Python Pretty Printers:
$ cd ~/.gdb_printers
$ svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python
Icinga 2 Pretty Printers:
$ mkdir -p ~/.gdb_printers/icinga2 && ~/.gdb_printers/icinga2
$ wget https://raw.githubusercontent.com/Icinga/icinga2/master/tools/debug/gdb/icingadbg.py
Now you'll need to modify/setup your `~/.gdbinit` configuration file.
You can download the one from Icinga 2 and modify all paths.
> **Note**
>
> The path to the `pthread` library varies on distributions. Use
> `find /usr/lib* -type f -name '*libpthread.so*'` to get the proper
> path.
$ wget https://raw.githubusercontent.com/Icinga/icinga2/master/tools/debug/gdb/gdbinit -O ~/.gdbinit
$ vim ~/.gdbinit
More details in the [troubleshooting debug documentation](https://docs.icinga.com/icinga2/latest/doc/module/icinga2/chapter/troubleshooting#debug).
