How to step into a c++ std library function in gdb/gud

Question

This is most likely an issue with g++/gdb/other, but an indirect issue within Emacs nonetheless.

Whilst debugging, I would like for Emacs to step into the standard library implementation of the overloaded << operator function called from object std::cout.
As is shown in the series of screenshots when the current source file (in the source file window) switches from main.cpp to funct.cpp when function funct() is called:

Screenshot 1
Just starting the debugging session.

Screenshot 2
One step taken; thus changing the source file I'm looking at.

Screenshot 3
One step taken; std::cout << "ok\n"; is completely stepped over; when I would like to be directed to another source file.

The command I used to compile the files:
g++ -g -std=c++11 main.cpp funct.cpp

If someone could guide me through step-by-step of how they got this to work, that would be a great example to learn from; or if any more information is needed (whether it be the system I'm using, file-paths, etc.), please ask away.

Answer 1

There's nothing you can do with Emacs that will change how this works, since you're just asking Emacs to ask gdb to step. Try compiling your program with -Og -ggdb, to ensure that you have the maximum amount of debugging information available.

And of course there are about a billion related options that you can use to control the amount of optimization the compiler does and the amount of debug information it includes. You should set aside a week to read through the gcc man page from top to bottom, so that you know them all. Have fun :)
