GDB Bootcamp

Survival of the fittest

Getting around

To start a session : $> gdb my-super-awesome-program
To start a session with arguments : $> gdb --args my-super-awesome-program --temperature hot --voltage high
To run (the thing starts paused) : (gdb) run
To pause (when the bloody thing is running) : Ctrl-C (once!!!!)

Setting these damn breakpoints

(gdb) b vftranscode.cpp :2751

Inspecting after a crash

Get the stack trace

(gdb) backtrace

If you cannot get the backtrace (call stack), your program might have exited. To prevent that, retry debugging it, but before running type this :

(gdb) handle SIG33 noprint nostop

(gdb) run

Get the current source location

(gdb) l

(gdb) s
