target type parameters
target
command does not repeat if you press RET again
after executing the command.
help target
info target
or info files
(see section Commands to specify files).
help target name
set gnutarget args
set gnutarget
command. Unlike most target
commands,
with gnutarget
the target
refers to a program, not a machine.
See section Commands to specify files.Warning: To specify a file format with
set gnutarget
, you must know the actual BFD name.
show gnutarget
show gnutarget
command to display what file format
gnutarget
is set to read. If you have not set gnutarget
,
GDB will determine the file format for each file automatically,
and show gnutarget
displays `The current BDF target is "auto"'.
Here are some common targets (available, or not, depending on the GDB configuration):
target exec program
target core filename
target remote dev
target remote
supports the load
command. This is only useful if you have
some other way of getting the stub to the target system, and you can put
it somewhere in memory where it won't get clobbered by the download.
target sim
target sim load runworks; however, you cannot assume that a specific memory map, device drivers, or even basic I/O is available, although some simulators do provide these. For info about any processor-specific simulator details, see the appropriate section in section Embedded Processors.
Some configurations may include these targets as well:
target nrom dev
Different targets are available on different configurations of GDB; your configuration may have more or fewer targets.
Many remote targets require you to download the executable's code once you've successfully established a connection.
load filename
load
command may be available. Where it exists, it
is meant to make filename (an executable) available for debugging
on the remote system--by downloading, or dynamic linking, for example.
load
also records the filename symbol table in GDB, like
the add-symbol-file
command.
If your GDB does not have a load
command, attempting to
execute it gets the error message "You can't do that when your
target is ...
"
The file is loaded at whatever address is specified in the executable.
For some object file formats, you can specify the load address when you
link the program; for other formats, like a.out, the object file format
specifies a fixed address.
load
does not repeat if you press RET again after using it.
