Things to check:
* Compiled with -g switch
* Correct file name [correct case, and extension if any]
specified e.g. gdb myFile.exe, and file is loaded i.e. the
preamble display appears
* Symbol file has been loaded i.e. it has not been been
deleted [should say so on preamble display]
* Set breakpoint at 'main' e.g. after loading file, issue:
break main
command
* In 'stepping through' the executable you are currently
in a context in which 'i' exists i.e. it is in scope
You may wish to access the 'man' page documention ['man gdb'], or the 'help'
command within gdb, or perhaps search for a gdb tutorial, for more
information
I hope this helps.
