llvm dev - Nov 2017 - Remotely launching a new process with LLDB

I'm trying to remotely launch and debug a new process with lldb without much
success.

Attaching to an already launched process works well by running these commands:

process connect <url>
process attach -P gdb-remote --pid <pid>


But if I want debugserver to launch the executable by itself I'm running
into troubles. Especially, I have no clue what arguments should I pass to target
create.

According to this page<https://lldb.llvm.org/remote.html> LLDB "will
transparently take care of [..] downloading the executable in order to be able
to debug", yet target create seem to always require a local file. If I
specify the remote file via -r I get either unable to open target file or remote
--> local transfer without local path is not implemented yet errors. If I set
the target to a local file (such as a local copy of the remote's loader
executable) without using -r, then attempt to run process launch -p gdb-remote
-s <remote path> LLDB will attempt running the local path on the remote
machine and fail.

What are the correct commands I need to use in order to launch a remote process?

I would recommend asking this on the lldb mailing list instead.
