Printing full backtrace in c++

Question

I want to dump a backtrace from a C++ program in Linux in a similar format as it is done in gdb. I tried to use the backtrace() and backtrace_symbols() functions for this purpose. These returned function names and offsets. I can use the __cxa_demangle() function to get a readable function name.

Is there any way to get the file/line positions too, as it is done by gdb?

Answer 1

How it's better to invoke gdb from program to print its stacktrace?`

Methode #4, shows a way to get filename and line. But uses a extern program..

If you don't mind really executing GDB to get a backtrace you can take a look at how the Warzone 2100 project does it. We're basically using a combination of these techniques to get GDB-quality output if possible and progressively fall back to simpler strategies (e.g. if GDB isn't available or libc doesn't provide backtrace()). (the gist of it resides in github.com/Warzone2100/warzone2100/blob/master/lib/… ) – Orpha
