title: Build a Linux executable using GCC
body: <p>I'm using <a href="https://en.wikipedia.org/wiki/Ubuntu_version_history#Ubuntu_8.10_(Intrepid_Ibex)" rel="nofollow noreferrer">Ubuntu 8.10</a> (Intrepid Ibex) and compiling C++ files with GCC, but when I compile, gcc makes an <code>a.out</code> file that is the executable. How can I make Linux executables?</p>
