| <span class="sc">gdb</span> enables developers to debug tasks running on |
| Sparclet targets from a Unix host. |
| <span class="sc">gdb</span> uses code that runs on |
| both the Unix host and on the Sparclet target. The program |
| <code>gdb</code> is installed and executed on the Unix host. |
| |
| <dl> |
| <dt><code>remotetimeout </code><var>args</var><dd><a name="index-remotetimeout-1371"></a><span class="sc">gdb</span> supports the option <code>remotetimeout</code>. |
| This option is set by the user, and <var>args</var> represents the number of |
| seconds <span class="sc">gdb</span> waits for responses. |
| </dl> |
| |
| <p><a name="index-compiling_002c-on-Sparclet-1372"></a>When compiling for debugging, include the options ‘<samp><span class="samp">-g</span></samp>’ to get debug |
| information and ‘<samp><span class="samp">-Ttext</span></samp>’ to relocate the program to where you wish to |
| load it on the target. You may also want to add the options ‘<samp><span class="samp">-n</span></samp>’ or |
| ‘<samp><span class="samp">-N</span></samp>’ in order to reduce the size of the sections. Example: |
| |
| <pre class="smallexample"> sparclet-aout-gcc prog.c -Ttext 0x12010000 -g -o prog -N |
| </pre> |
| <p>You can use <code>objdump</code> to verify that the addresses are what you intended: |
| |
| <pre class="smallexample"> sparclet-aout-objdump --headers --syms prog |
| </pre> |
| <p><a name="index-running_002c-on-Sparclet-1373"></a>Once you have set |
| your Unix execution search path to find <span class="sc">gdb</span>, you are ready to |
| run <span class="sc">gdb</span>. From your Unix host, run <code>gdb</code> |
| (or <code>sparclet-aout-gdb</code>, depending on your installation). |
| |
| <p><span class="sc">gdb</span> comes up showing the prompt: |
