Sorry I didn't make myself clear. The reason I asked YOU to do it is because i tried it on my system and im not getting the backtrace (it's all question marks).
Attach the core to gdb. At the gdb prompt, go to frame 2 by typing (gdb) f 2 There, for each of the variables i asked you to get the values of, type p followed by the variable name. For instance, to get the value of the variable 'odirect', do this: (gdb) p odirect and gdb will print its value for you in response. -Krutika On Mon, Aug 1, 2016 at 4:55 PM, Mahdi Adnan <mahdi.ad...@outlook.com> wrote: > Hi, > > How to get the results of the below variables ? i cant get the results > from gdb. > > > -- > > Respectfully > *Mahdi A.
