"description": "Enable pretty-printing for gdb", Set a breakpoint by clicking left of the line number, a red circle will appear. I added an extra line of code to your example. Std::cout << folder << '\n' // Set a breakpoint here Yes, you can automate the extra argument by adding the option to your launch.json file for the VS Code project.Did you install the build-essential package? But your compiler is saying that a file doesn't exist. Since mine didn't fail, I can't offer much help here. I didn't name my executable, so my invocation looked like this: Is the name of your executable main? I compiled on Debian using gcc 5.5. I attempted to compile and run your program, and it worked just fine.
gdb can do this for some segmentation faults generally you'll want to learn how to move through the code yourself. Once you get set up, you're now ready to debug with VS Code. I prefer also adding in -O0 to minimize optimizations. Compile your program with -g at a minimum. You then need to choose a configuration in the debug panel. If you want to debug with VS Code, there's a setup that you have to do for each project, but after the setup is complete, it's straightforward. Is possible to do the same thing when debbuging, without writing the folder directly in the program, or using cin? main /home/lorenzo/Images, so I pass the folder to the program in this way. For "running" the program from the terminal I write. "Unable to open 'raise.c': Unable to read file (Error: File not found (/build/glibc-4WA41p/glibc-2.30/sysdeps/unix/sysv/linux/raise.c))."ġ) Is possible to display the number of the line where the error occurs? (In this case line 6)Ģ) Why does this error happen, and how to avoid it?ģ) For avoiding this problem I can write, for example: string folder = "/home/lorenzo/Images" īut I don't want to do that. What(): basic_string::_M_construct null not valid 
"terminate called after throwing an instance of 'std::logic_error' Good evening to everyone, I try to debug this little program in visual studio code in ubuntu: #include īut the debug terminate with this error in the terminal:
