I am currently enrolled in a programming fundamentals class in c++. I've set up Visual Studio 2017 and am trying to run the example code from the textbook. Whenever I try to debug anything, including the sample "hello world" code, I get these errors.

I've tried changing the location of the project and triple-checked the code.

#include "pch.h"
#include <iostream>

int main()
{
    std::cout << "Hello World!\n"; 
}

It is supposed to output "hello world", but I get these errors instead.

  • BTW, I highly recommend not using precompiled headers, e.g. `pch.h` until you are confident in writing large programs. The benefit is negligible for small programs. – Thomas Matthews Oct 02 '19 at 18:12

    Most of those are warnings indicating that the debug symbols for the DLLs could not be found. You can still debug your program; you want be able to expand into any of the DLL functions (which are not often required). – Thomas Matthews Oct 02 '19 at 18:14

    There should be a duplicate of this ... – Thomas Matthews Oct 02 '19 at 18:14
  • There seems not to be any error. I think your program runs, outputs its text into the console window (which you probably missed, since its very fast), and then instantly exits. Try to set a breakpoint (F9) before starting your debug session. You should add a `return 0;` in `int main()` body anyway. – user2328447 Oct 02 '19 at 18:20

  • @user2328447 `return 0;` is implicit in `main`, otherwise I second your comment. – Quentin Oct 03 '19 at 11:43

PDB file is a debug information file used by Visual Studio. These are system DLLs, which you don't have debug symbols for. Go to Tools->Options->Debugging->Symbols and select checkbox "Microsoft Symbol Servers", Visual Studio will download PDB files automatically.
