After trying to build this simple program:

#include <iostream>
#include <cstdlib>

using namespace std;

void main()
{
    int a = 6;

    cout << a << endl;
}

I get many "unresolved external symbol" errors:

What is causing this and how this can be fixed?

  • Please add "/VERBOSE:LIB" to linker options and post the output. Propably some of your LIB pathes are incorrect. – zett42 Sep 08 '17 at 13:46
  • I put that library in linker:Input:Additional Dependencies and got all LNK2001 errors and the LNK1120 error. Still 12 errors. –  Sep 08 '17 at 14:34

I encountered errors much the same as you report here. I solved my issues by including these libraries for the Release config:

vcruntime.lib

And for the Debug config:

vcruntimed.lib
ucrtd.lib

It is unclear to me why the debug version, vcruntimed.lib, would require an additional library, but it does.

This question is related to LNK2019 unresolved external symbol _CrtDbgReport referenced in function _CRT_RTC_INIT SDL2
