The "remote" target does not support "run". Try "help target" or "continue".
(gdb) help target
Connect to a target machine or process.
The first argument is the type or protocol of the target machine.
Remaining arguments are interpreted by the target protocol. For more
information on the arguments for a particular protocol, type
`help target ' followed by the protocol name.
List of target subcommands:
target bsd-uthreads -- BSD user-level threads
target core -- Use a core file as a target
target exec -- Use an executable file as a target
target extended-remote -- Use a remote computer via a serial line
target record -- Log program while executing and replay execution from log
target record-btrace -- Collect control-flow trace and provide the execution history
target record-core -- Log program while executing and replay execution from log
target record-full -- Log program while executing and replay execution from log
target remote -- Use a remote computer via a serial line
target tfile -- Use a trace file as a target
Type "help target" followed by target subcommand name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.
