Issue while debugging Linux based C++ code visual studio code

Question

I am trying to debug my code in visual studio code in Linux - Ubuntu. I have configured the debugging configurations according to the specification. But when trying to debug I am getting the following error.

The salient part of your error is Stopped due to shared library event (no libraries added or removed) Loaded '/lib64/ld-linux-x86-64.so.2'. Symbols loaded. [Inferior 1 (process 18634) exited with code 0177] The program '/home/source/src/.libs/main' has exited with code 177 (0x000000b1). Where it appears you are attempting to load and compile/run in gdb a Linux shared-object library under a VS compile. I don't know how that would work under WSL, but you cannot expect VS (at least the versions I've worked with) to use a .so instead of a windows .dll. — David C. Rankin

@DavidC.Rankin I'm facing the same problem, As you said VS cant use .so files. this mean I can't debug a program that uses .so files under VS, am I right? — HMD

@HMD You have options. WSL (whichever distro you choose) will provide gcc, so you can build your code with gcc (using the -g option to generate the gdb symbol file) Then you can debug with gdb. — David C. Rankin

Because not all libraries (.a, .so) are linked to you project. I had the same problem. gdb outputs this error when it encounters a library call to a library that is not linked.

You have compiled your program without debugging information. Compile it with -g compiler and linker option.
