Hi Ricardo,
lldb should work OK with Rust executables. The error you mention should
be solved by also specifying the file containing the line you want to
break in. So instead of writing just `b -l 5`, try `b -l 5 -f main.rs`
instead (specifying the correct source filename, of course). The command
`b main.rs:5` (i.e. like you would type it in GDB) should also work.
Cheers,
Michael

Eric,
I tried lldb with rust:
You can notice that it runs, but I could not set breakpoint,
Anyway is not a problem work with Ubuntu on my VirtualBox, but could
be nice have another option. :)
Thanks

Hello Ricardo!

To be sure lldb was working, I tried with a hello world in c, and
worked fine:
$ lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) break 5
invalid command 'breakpoint 5'
(lldb) b -l 5

This seems bad. Does the file exist in that path?

This is your other real problem. You need to code sign your gdb in
order for it to work. Can you try lldb and see how that works for you?
Alternately you'll need to sign the gdb you built.
