Usually when you want to debug an application, you launch it from EiffelStudio and the debugger is automatically attached to the execution of the application.
|
|
However for specific needs (such as server development), you might want to start the execution outside EiffelStudio, and then attach EiffelStudio's debugger to it.
|
|
|
|
Requirements:
|
|
* The application should be compiled in workbench mode.
|
|
* EiffelStudio should be open on the project which was used to compile the application.
|
|
|
|
How to make it work?
|
|
* On the application side, at some point you will need to provide a port number, and at that point the application will wait for the debugger.
|
|
|
|
To speciffy the port number you have two possibilities:
|
|
* setting the <code>ISE_DBG_PORTNUM</code> environment variable to a specific port number. When the environment variable is set, the application after starting will immediately put itself in a mode where it will wait for EiffelStudio to attach the process
|
|
* calling <eiffel>{RT_DEBUGGER}.rt_workbench_wait_for_debugger (a_port_number: INTEGER)</eiffel> from the program itself. In this case, the program will put itself in a mode where it will wait for EiffelStudio to attach the process when you call this routine.
|
|
|
|
To attach the process from EiffelStudio, follow the menu path <code>Execution->Attach Debuggee</code> and provide the same port number as specified above.
|
|
(Note that you can add the associated command to the execution tool bar.)
|
|
|
|
At this point EiffelStudio is able to debug the application just as if the application had been launched by EiffelStudio.
