| Sourcery G++ includes copies of run-time libraries that have been built |
| with optimizations for different target architecture variants or other |
| sets of build options. Each such set of libraries is referred to as a |
| <em class="firstterm">multilib</em>. When you link a target application, |
| Sourcery G++ selects the multilib matching the build |
| options you have selected. |
| </p><p> |
| <span>Each multilib</span> |
| |
| corresponds to a <em class="firstterm">sysroot</em> directory |
| which contains the files that should be installed on the target system. |
| <span> |
| The sysroot contains the dynamic linker used to run your applications |
| on the target as well as the libraries. |
| </span> |
| <span> |
| Refer to <a class="xref" href="included-libraries.html" title="3.6. Using Sourcery G++ Lite on GNU/Linux Targets">Section 3.6, “Using Sourcery G++ Lite on GNU/Linux Targets”</a> for instructions |
| on how to install and use these support files on your target GNU/Linux |
| system. |
| </span> |
| <span> |
| You can find the sysroot directories provided with Sourcery G++ in the |
| <code class="filename">arm-none-linux-gnueabi/libc</code> directory of your installation. |
| |
| </span> |
| <span> |
| In the tables below, the dynamic linker pathname is given relative |
| to the corresponding sysroot. |
