<note> - Currently, Eclipse does not support SSH port forwarding. - Consequently, if you need to run or debug a remote - application using the host display, you must create a - tunneling connection from outside Eclipse and keep - that connection alive during your work. - For example, in a new terminal, run the following: - <literallayout class='monospaced'> - $ ssh -XY <replaceable>user_name</replaceable>@<replaceable>remote_host_ip</replaceable> - </literallayout> - Using the above form, here is an example: - <literallayout class='monospaced'> - $ ssh -XY root@192.168.7.2 - </literallayout> - After running the command, add the command to be executed - in Eclipse's run configuration before the application - as follows: - <literallayout class='monospaced'> - export DISPLAY=:10.0 - </literallayout> - Be sure to not destroy the connection during your QEMU - session (i.e. do not - exit out of or close that shell). - </note> - <orderedlist> - <listitem><para>Select "Debug Configurations..." from the - "Run" menu.</para></listitem> - <listitem><para>In the left area, expand -
