In general, GDB mainly completes the following four areas of functionality: (1) Start your program, you can follow your custom requirements of the arbitrary operation of the program.(2) Allow the program to be debugged to stop at the breakpoint where you specified the adjustment. (A breakpoint can be a conditional expression)(3) When the program is stopped, you can check what happened in your program at this time.(4) Dynamically changing the executio

Use GDB to Debug PHP code to solve the endless loop of PHP code. When I used GDB to Debug PHP code and solve the PHP code endless loop problem and recently helped my colleagues solve the SwooleServer problem, I found that one worker process has been in the R state, and the CPU consumption is very high.

How does GDB debug the online http Process of Segment Fault? Some problems can only be reflected on online machines with high concurrency traffic, and the testing machines cannot reproduce them. We can use GDB to solve this problem. Start GDB in the command line. GDB En

Debug multiple processes with GDB Program For a while, I haven't written technical things. ^_^. As we all know, GDB is the leader in debugging programs in Unix/Linux. It has powerful functions. We usually use some of its most basic functions, and generally debug single-process programs. The problem in a recent proj

use GDB to debug Android NDK native (c + +) programs First of all, here the so-called NDK native program is not related to Android upper Java applications, and does not need to involve jni to encapsulate the native interface, in general, is to compile a pure C + + program, push to the Android device or emulator, Then run the program on the device. Debugging is done by attach to Gdbserver.

Look at Run-time data——————— When you debug a program, when the program is stopped, you can use the Print command (the Shorthand command is P), or the synonymous command inspect to view the current program's running data. The Print command is in the following format: Print Print/ One, Expression Print, like many gdb commands, can accept an expression that GDB
