使用gdb跟踪C ++中的函数调用

Question

I have a system developed in C++ on Linux platform. I am doing some debugging of this system. I want to look for the complete sequence of function calls to a function. Lets assume the functions are called in the following sequence

function_1 -> function_2 -> function_3 -> function_4

If I put a break point at function_4, the execution will be holded at that point. I want to see that functions_1, function_2 and function_3 are called before function_4. If there any gdb command to trace these function calls?

Thanks, Ankur

Answer 1

You want a backtrace. The gdb command bt will show exactly what you are interested in.

Answer 2

bt：backtrace http://sourceware.org/gdb/onlinedocs/gdb/Backtrace.html

Answer 3

If function_1() calls function_2() which calls function_3() etc

You can set your breakpoint in function_4() and you use the command

where

To print a backtrace of the stack

Another tool that may be useful is valgrind with the callgrind tool
