  1. CO004 Projects on Operating Systems Debug 2 gdb and insight

  2. GDB commands • Use gdb directly (commands only) • s 2 (step in 2 lines) • n (step over 1 lines) • p ptr (print the value of ptr) • bt (back trace) • b (break point) • c (continue to run)

  3. GDB • Demo: • bugs.c • Prerequisite • Compile using proper parameter • gcc -ggdb -o bugs bugs.c • Reference • GDB Online Manual http://www.gnu.org/software/gdb/documentation/

  4. Insight+gdb • Things to Install • gcc • vim (or other text editor) • gdb • insight (or other debugger like “ddd”)

  5. Before Installation • Check which one has been installed • gcc –-version • gdb -–version • vim --version • insight --version

  6. You should see the source code Remember to use “gcc -ggdb xxxxxxx”, otherwise you cannot see any source code

  7. Breakpoint Program will stop before executing this statement!

  8. Breakpoint Program will stop before executing this statement!

  9. • Run : run/start the program • Step: Execute the current line of code, jump into the function if possible • Next: Similar to “Step”, but don’t jump into the function • Finish: Jump out of the current function • Continue: Execute until hitting another breakpoint
