gdb notes
introduction
test is binary file which is created by a cpp source file and complied with -g parameter
fundamental
gdb test : run test binary file with gdb
run : run test file
run arg1 arg2 ... : run test file with parameters
kill : kill command kills the stopped program, finishes debugging
display
list : list 10 lines of source code and when repeating, it lists next 10 lines
backtrace : show crash point and information about it, actually crash stack
frame : the command is used to display backtrace log line for more details
info frame : more more details about crash point
info locals : information about local variables
info args : information about arguments
info breakpoints : information about breakpoints (lines, status, address etc)
info watchpoints : information about watchpoints
info registers : information about registers
disassemble main : display main function memory address
help
help : display gdb help menu
debugging
call foo() : the call command calls function named foo
break 7 : the command places a breakpoint on 7th line
break test.cpp:10 : for placing a breakpoint on 10th line of test.cpp
break foo : for placing breakpoint for a function named foo
break Test::foo(int) : specific usage of break command for cpp class functions (Test is a class)
tbreak : this command creates a temporary break point which is used once
disable 2 : the disable command disables second breakpoint
ignore 3 7 : ignores all breakpoints from third breakpoints to seventh breakpoints
clear 1 : remove first breakpoint
continue : if the program is stopped in any way, continue can continues the process
next : when the program is stopped, the next goes on. (go over function)
step : when the program is stopped, the step goes on. (go into function)
watchpoint
watch x : the command watch variable content named x (the breakpoint have to be used after x)
rwatch x : read-only watch point for x variable
awatch x : read-write watch point for x variable
