Re: [Ltib] Ltib and gdb

[Stuart Hughes]

Hi Giogio,

The gdb for the host is under the bin directory of your LTIB project. 
As it is tailored to your target and not a generic variant.

I've had mixed success with cross debugging.  Sometimes it works well. 
Generally if I use it, I run a front end like ddd.  Typically the 
process is this

---+ Build an un-stripped package and deploy to target image
$ ./ltib -p <pkg> -m prep
$ ./ltib -p <pkg> -m scbuild
$ ./ltib -p <pkg> -m scdeploy

# boot the target and start gdbserver (the executable may be stripped)
 gdbserver :1234 /usr/bin/pkgexecutable

---+ on the host in your LTIB project directory
$ ddd --debugger bin/gdb rpm/BUILD/<pkg>/path/to/some_exe_unstripped

---+ in the debugger
gdb> target remote targetip:1234
gdb> b main
gdb> continue


Regards, Stuart
