[lldb-dev] Remote Debugging on Linux

[Greg Clayton]

The first way to do this is to use the lldb-platform to allow you to view and launch processes on the remote host.

On the remote machine launch lldb-server:

remote.foo.com% lldb-server platform --listen=2000 --stay-alive

Then on your host machine:

host.bar.com% lldb
(lldb) platform select remote-linux
(lldb) platform connect connect://remote.foo.com:2000

Now you have a live connection to a platform server on the remote host so you can list existing processes:

(lldb) platform process list
(lldb) platform process attach --pid ...

Or you can launch:

(lldb) file /path/to/binary
(lldb) process launch -- arg1 arg2

The platform will launch a lldb-server to debug your programs on the other system.




The other is to just directly debug a process. In this case we don't go through the platform, we just start lldb-server on 

remote.foo.com% lldb-server gdbserver host.bar.com:2000 -- arg1 arg2

Then attach to it:

host.bar.com% lldb
(lldb) file /path/to/binary
(lldb) process connect connect://remote.foo.com:2000

Now you will be stopped at the program entry point and ready to debug a single process.

All of this is of course using the top of tree SVN sources. It will change a bit if you are using older sources.
