Hi all,

I'm trying to build, run, and debug a C++ application inside a docker container. I've got it configured to be able to build and run inside the container, however debugging is throwing the following error:

Error in final launch sequence:

Failed to execute MI command:
-target-select remote localhost:2345
Error message from debugger back end:
Remote register badly formatted: T0506:0000000000000000;07:f0ebffffff7f0000;10:209cddf7ff7f0000;thread:p7.7;core:0;
here: 00000000;07:f0ebffffff7f0000;10:209cddf7ff7f0000;thread:p7.7;core:0;

In the console of eclipse I get the following log:

Listening on port 2345
Remote debugging from host 172.17.0.1
readchar: Got EOF
Remote side has terminated connection.  GDBserver will reopen the connection.
Listening on port 2345

Locally I have gdb version 7.7.1 as installed through MingW64; inside the container I have gdbserver 7.7.1 running.

Any help would be greatly appreciated.

Hi all,

I've found the problem, and it was that my local gdb only supported i386 architecture, whilst the gdbserver was running on an x86_64 architecture. Using a gdb version that supported x86_64 fixed the issue.
