GDB Tutorial{ }GDB TutorialI recommend using instead of GDB, as it is helpful to see what is visually taking place. CGDB uses GDB behind the scenes and shows you the code as it is being executed.LaunchingTo use GDB you must compile with the -g compiler flag. This is so the compiler and linker keep all the useful debugging information (symbol and code information).Launch GDB by telling it what program to debug: gdb myProgram or cgdb myProgram.NOTE: You could run your program at this point, but it won't be useful for debugging. You'd want to set a breakpoint first.If you want to run your program use the run command (shorthand: r).To quit GDB use the quit command (shorthand: q).BreakpointsBreakpoints can be set using the break command (shorthand: b).There are multiple ways to set breakpoints, by:line number: b 6function name: b foofile name and line number: b foo.c:6Make things easier by setting a breakpoint before running your program.Set it on the first line using b 1Run your program using r.By doing this you can step through your program one line at a time.NOTE: A breakpoint stops execution before the line of code is executed.SteppingStep into the current line with the step command (shorthand: s) when execution is paused.For example, if execution is paused on the line x = foo();, the command s will enter foo() and break at the first line of foo().Step over the current line with the next command (shorthand: n). It will execute all the code until it reaches the next line in the current scope.In the case of x = foo();, all of foo() will be executed and its returned value will be assigned to x. Execution will then pause on the line that comes after x = foo();.Step out of a function with the finish command (shorthand: fin). It will finish the current function and pauses execution once the function is completed.Complete execution of a loop from the last line of the loop using the until command and execution will resume on the line below it.Resume normal execution with the continue command (shorthand: c); it'll stop at the next breakpoint.Program StateView the value of a variable (when execution is paused) with the print foo command (shorthand: p foo). You can even view the result of an expression, such as p listContainsFoo().Change the value of a variable with the set foo = 10 command.Show the stack with the info stack command (shorthand: i s). View stack frame #3 with the frame 3 command.Advanced BreakpointsConditional breakpoints are used to pause execution only if some condition is met.You can create them with expressions.For example, b 6 if x == 0 or b 6 if listContainsFoo().See the list of current breakpoints with the info breakpoints command (shorthand: i b).NOTE: Each breakpoint is given a number.Delete a breakpoint in two ways:Delete a breakpoint given its breakpoint number: delete 1 (shorthand: d 1)Follow the same rules you used to create the breakpoint: clear foo.c:6 (shorthand: cl foo.c:6)Temporarily disable a breakpoint with the disable 1 command (shorthand: dis 1).Re-enable breakpoints with the enable 1 command (shorthand: en 1).CAUTION: The clear command shorthand is cl. The continue command shorthand is c. You do not want to mix up these two.CGDBIf you are using CGDB know these shorthand commands: Escape key: move cursor to source code view↑ and ↓keys: scroll through the c odei key: move the cursor to the GDB view↑ and ↓ keys: scroll through GDB command historyCreditsWritten byChris BlumeEdited byMorgan LandisDesigned bySan Chung, Online GDB is online compiler and debugger for C/C++. You can compile, run and debug code with gdb online. Using gcc/g++ as compiler and gdb as debugger. Currently C and C++ languages are supported., Os breakpoints são lugares (linhas ou funções) onde você quer que o programa pare a execução e espere por um comando seu (para imprimir variáveis, para executar uma linha por vez, etc). Você pode colocar um breakpoint em uma função e a execução irá parar sempre quando a função for chamada. Exemplo:.
GDB, the GNU Project debugger, allows you to see what is going on `inside' another program while it executes -- or what another program was doing at the moment it crashed. GDB can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act:, gdb is in the gnu package on CEC machines. If you don't have this package loaded then type pkgadd gnu at a shell prompt. If you can run g++, then you will be able to run gdb. gdb can only use debugging symbols that are generated by g++. For Sun CC users, there is the dbx debugger which is very similar to gdb., To use GDB you must compile with the -g compiler flag. This is so the compiler and linker keep all the useful debugging information (symbol and code information)., GDB, or GNU Debugger, is a powerful tool for debugging programs written in C and C++. It allows developers to see what is occurring inside a program while it executes, or what it was doing at the moment it crashed., The Online GDB Compiler allows for seamless, collaborative debugging, so you and your team can whip that code into shape together. It’s like a coding jam session, but with fewer guitars and more debugging tools!, https://sourceware.org/pub/gdb/releases/ (mirrors) Sources to the current development version are also available using HTTPS, git and WWW. See current. We've got GDB releases going back to the 2.4/2.8 timeframe in 1988. They're all on-line in the GDB HTTPS directory in:.
