What is the difference between native gdb and remote gdb?


Asked by Gracelynn Cortes on Dec 04, 2021 FAQ



Those programs might be executing on the same machine as GDB (native), on another machine (remote), or on a simulator. GDB can run on most popular UNIX and Microsoft Windows variants, as well as on Mac OS X. What Languages does GDB Support?
Subsequently,
GDBserver takes control of the application being debugged, then waits for instructions from a remote instance of GDB running on a development workstation. Typically, the development workstation has a different processor (say, an i686 class processor) than the target platform (which may be ARM, PowerPC, or something else).
Consequently, The protocol talked between the gdb “client” and the gdb “server” is referred to as “GDB Remote Serial Protocol” ( GDB RSP) 6. If we take a look at the GDB RSP docs we will find that the ‘z’ packets are used to configure breakpoints. The format of the commands are ‘Z/z type,addr,kind’ where:
Additionally,
] gdbserver is a control program for Unix-like systems, which allows you to connect your program with a remote GDB via target remote ---but without linking in the usual debugging stub. gdbserver is not a complete replacement for the debugging stubs, because it requires essentially the same operating-system facilities that GDB itself does.
Likewise,
The stripped version is to be run with GDBserver on the target platform, and the non-stripped copy is to be loaded into GDB on the development workstation. Remote debugging is rather straightforward: on the target platform, launch the application with GDBserver, while specifying the host and port for listening to an incoming TCP connection:
