In Linux, you can debug with GDB using the following methods:<\/p>\n

    \n
  1. Add debug information at compile time: When compiling source code, you can use the -g option to generate an executable file with debug information. For example, use gcc -g file.c -o file to compile the source code named file.c and generate an executable file named file.<\/li>\n
  2. Start the GDB debugger: Launch the GDB debugger by entering the gdb command in the terminal.<\/li>\n
  3. Specify the executable file for debugging: In the GDB debugger, use the file command to specify the executable file for debugging. For example, use file file to specify a executable file named file.<\/li>\n
  4. Set breakpoints: Use the break command to set a breakpoint at a specific location in the code. For example, use break main to set a breakpoint at the beginning of the main function.<\/li>\n
  5. Run a program: use the run command to run the program. When the program reaches a breakpoint, it will pause.<\/li>\n
  6. Perform debugging operations: Once the program pauses, you can use the following commands to carry out debugging operations.<\/li>\n
  7. Next: Execute the next line of code without entering the function call.<\/li>\n
  8. Step: Execute the next line of code and enter the function call.<\/li>\n
  9. Keep running the program until the next breakpoint or until the program finishes.<\/li>\n
  10. print: display the value of the variable.<\/li>\n
  11. backtrace: display the function call stack.<\/li>\n
  12. exit:
    \nExit the GDB debugger.<\/li>\n
  13. Observing variables and memory: You can print the value of a variable using the print command, or view the contents of memory using the x command. For example, use print variable to print the value of a variable named variable, or use x\/s address to view the string at the address address.<\/li>\n
  14. Debugging finished: After finishing debugging, you can use the quit command to exit the GDB debugger.<\/li>\n<\/ol>\n

    These are the basic methods for debugging using GDB. GDB also offers many other functions and commands that can be further learned and used as needed.<\/p>\n","protected":false},"excerpt":{"rendered":"
