C++ debugging method to bypass library files

C++ debugging method to bypass library files

Sometimes we want to only debug our own code when debugging c++ code, without entering the library file. For example, in the following piece of code, we want to execute at f()will step intodirectly enter the body of display（）the function , but unfortunately, until 2022, c++ does not support the "Just my code" debugging option very well.

#include "stdafx.h"
#include <functional>
#include <iostream>

void display() {
    
    
	std::cout << "Hello" << std::endl; // step into should go here
}

int main() {
    
    
	std::function<void()> f = &display;
	f(); // Step into here should go directly to "display()"
}

Currently, I have found the following solutions.

Solution 1: Debugging with Visual Studio

When using visual studio to debug c++ code, the "just my code" option is enabled by default, so if you are generating a console program for the Windows platform, executing step into will skip the library file by default.

But this method does not support local computer Cmake projects.

Solution 2: Visual Studio + Cmake

Fortunately, there is an option in Cmake to enable "Just My Code" support for the Visual Studio debugger. Just add the following line to the CmakeLists.txt file.

set (CMAKE_VS_JUST_MY_CODE_DEBUGGING 1)

However, this method only supports Cmake projects under the local computer. If you want to build a Cmake project under remote Linux, it is still not supported.

Others, there is a solution to [^1] from the level of gdb, but the effect is still not ideal.
