### 1.8.4 Tools that were used to create MySQL

[]()

 The following is a list of some of the tools we have used to create MySQL. We use this to express our thanks to those that has created them as without these we could not have made MySQL what it is today.

* Free Software Foundation

   From whom we got an excellent compiler (**gcc**), an excellent debugger (**gdb** and the `libc` library (from which we have borrowed `strto.c` to get some code working in Linux).

* Free Software Foundation & The XEmacs development team

   For a really great editor/environment.

* Julian Seward

   Author of `valgrind`, an excellent memory checker tool that has helped us find a lot of otherwise hard to find bugs in MySQL.

* Dorothea Lütkehaus and Andreas Zeller

   For `DDD` (The Data Display Debugger) which is an excellent graphical front end to **gdb**).
