| <h5 class="subsubsection">15.4.7.6 Tasking Support when Debugging Core Files</h5> |
| |
| <p><a name="index-Ada-tasking-and-core-file-debugging-877"></a> |
| When inspecting a core file, as opposed to debugging a live program, |
| tasking support may be limited or even unavailable, depending on |
| the platform being used. |
| For instance, on x86-linux, the list of tasks is available, but task |
| switching is not supported. On Tru64, however, task switching will work |
| as usual. |
| |
| <p>On certain platforms, including Tru64, the debugger needs to perform some |
| memory writes in order to provide Ada tasking support. When inspecting |
| a core file, this means that the core file must be opened with read-write |
| privileges, using the command ‘<samp><span class="samp">"set write on"</span></samp>’ (see <a href="Patching.html#Patching">Patching</a>). |
| Under these circumstances, you should make a backup copy of the core |
| file before inspecting it with <span class="sc">gdb</span>. |
