debuginfo-install is a command of yum-utils, so yum install yum-utils debuginfo-install glibc if the warning’s still there, edit /etc/yum.repos.d/CentOS-Debuginfo.repo, set enabled=1
You can simply do this print {var1,var2,var3,var4} This will do the job.
Put a breakpoint at the exit of your program that triggers the run command, and don’t forget set pagination off. Information on settings commands is available in the Breakpoint Command Lists section of the gdb documentation. In short: set pagination off break _exit commands run end After the commands line you’ll see that the next … Read more
Yeah, disassemble is not the best command to use here. The command you want is “x/i” (examine as instructions): (gdb) x/i 0xdeadbeef
You need the /t switch which works with both p and x: (gdb) p /t 0x0000000000400398 $1 = 10000000000001110011000 See help x for more info on the FMT (format) switches.
As I remember it I had some trouble with the straight load command too, so I switched to “flash write_image erase my_project.hex 0 ihex” .. obviously I was using hex files but it looks like elf files should work to, see http://openocd.org/doc/html/Flash-Commands.html … the good thing about this command is it also erases only the … Read more
jump +1 jumps to the next line line i.e. skipping the current line. You may also want to combine it with tbreak +1 to set a temporary breakpoint at the jump target. See http://sourceware.org/gdb/current/onlinedocs/gdb/Specify-Location.html for more ways of expressing locations with gdb. Note that without a breakpoint gdb is likely to continue execution normally instead … Read more

One way to see the GDB output history in TUI mode is to enable logging: set trace-commands on set logging on and then tail the log in another shell: cd where/gdb/is/running tail -f gdb.txt This has the advantage of separating scrolling from command interaction, so you can type commands while viewing some past section of … Read more
Turning confirmation prompts off globally disabled many other useful checks, such as the one to ask you if you really want to delete all breakpoints when you type “delete”. It would be better to disable the prompt only for the quit command. You can do that by adding this hook to your ~/.gdbinit (for current … Read more
