[cdt-dev] Antwort: Re: Using Eclipse CDT to debug process running on a r

[Bewoayia Kebianyor <Bewoayia.Kebianyor@xxxxxxxx>]

Hello John,

thanks for the response. I used the GDB Hardware Debugging Launch configuration type and had the following error:

Error in final launch sequence
Failed to execute MI command:
-target-select remote localhost:1234

Error message from debugger back end:
Command 'target-select'. Current SBTarget is invalid
Command 'target-select'. Current SBTarget is invalid


On the Server, lldb-server is running. This error occurs for both gdb and lldb-mi as client.

Is there a tutorial on how to implement a lunch Configuration for specific usecase or modify an existing one? I would be grateful to get a link to this.

Thanks and Regards,

Bewoayia

Betreff: Re: [cdt-dev] Using Eclipse CDT to debug process running on a remote Instruction Set Simulation running LLDB-Server - suppress eclipse sending -exec-continue

Hello Bewoayia

Take a look at the 'GDB Hardware Debugging' launch configuration type. 
It offers more flexibility to specify which GDB commands are issued as 
part of the launch sequence. You can specify both GDB/MI commands and 
non-MI commands in the Initialization Commands and Run Commands boxes.

Regards

On a remote machine an ISS simulator is started which started an LLDB server and waits for the client connection and further commands. I have used the standard C/C++ Remote Application Launch Configuration to launch a debug session for connecting to the server from eclipse. Instead of GDB, the LLDB-MI (for target system) is used as debugger. The client connects from eclipse to the target, as requires, but fails when the -exec-continue command is sent because the process has not yet been attached to at the server. Therefore, I would like to prevent eclipse from sending the exec-continue command after the connection to the server is established. Instead I would like to attach the process by sending "process attach pid" command. Using lldb-mi from the commandline works as expected for debugging the process running in the ISS.

I would later like to control/manage the commands sent from the client to the target for watching variables, mem etc.
