<h4 class="subsubsection">15.4.10.8 Tasking Support When Debugging Core Files</h4>
|
|
<a name="index-Ada-tasking-and-core-file-debugging"></a>
|
|
|
|
<p>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.
|
|
</p>
|
|
<p>On certain platforms, 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>"set write on"</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 <small>GDB</small>.
