Gdb Command Line

When the program is stopped, the first thing you need to do is to see where the program stops. When your program calls a function, the address of the function, the function arguments, the local variables within the function are pressed into the stack. You can use the GDB command to view the information in the current stack. Here are some GDB commands for viewing the function call stack information: BACKTRACEBT Prints all the information for the current function call stack. such as: &http://www.aliyun.com/zixun/aggregat ...

Display source code GDB can print out the source code of the program being debugged, of course, must add-g parameter when compiling the program, compile the source program information into the execution file. Otherwise you will not see the source program. When the program stops, GDB reports that the program is parked on the first line of that file. You can use the List command to print the source code of the program. Let's take a look at the GDB command to view the source code. List <linenum> Display the source program around the LineNum line. List <fu ...

In the debugger, pausing a program to run is necessary, and GDB can easily suspend the program. You can set the program to stop in which line, under what conditions to stop, in the receipt of what signal to stop and so on. To make it easier for you to view run-time variables and the run-time process. When the process is stopped by GDB, you can use the Info program to see if the application is running, the process number, and why it was paused. In GdB, we can have several pauses: breakpoints (breakpoint), observation points (Watch point ...).

GDB is a powerful UNIX program debugging tool released by the GNU Open source organization. Perhaps, you like the graphical interface, such as VC, BCB debugging IDE, but if you are in the UNIX platform to do the software, you will find that the debugging tool GDB is more than VC, BCB graphics debugger more powerful features. The so-called "inch, the ruler is short" is this truth.

Wait, is it necessary to remember so many shortcuts? It's so complicated! We strongly recommend that you remember to significantly improve operational efficiency. And this is the key binding of the ReadLine control, which you can use in any program that uses the ReadLine control. For example, Bash, lftp, gdb and other programs, and Linux, the most famous Emacs editor, but also this style of the key binding (in fact, the ReadLine using Emacs-style key binding to), and even Firefox, can also use similar style of shortcut keys ...
