Studio 2008 - "LNK2019: unresolved external symbol" error « on: June 04, 2012, 05:01:08 PM » Here is a VS project that
Error Lnk2019 Unresolved External Symbol Main Referenced In Function __tmaincrtstartup
fails to compile and I don't know why. The project looks like this:sum.cppCode: [Select]// sum.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include
extern "C" int sumX(void);
int https://social.msdn.microsoft.com/Forums/vstudio/en-US/64ce17cd-9471-4f55-9311-4a1561ed3c48/error-lnk2019-unresolved-external-symbol-vs2008?forum=vclanguage main()
{
std::cout << sumX() << "\n" ;
return 0;
}
sum.asmCode: [Select]section .text ;
global _sumX ;
_sumX:
mov eax,7
ret
Why does that fail to compile? It looks like the linker somehow fails to add the _sumX() function to the project, but I don't know if this is the case / why it happens.The error://update:- changing the https://forum.nasm.us/index.php?topic=1408.0 name of the sum.cpp file - new errors*- changing the name of the sum.obj file - the program compilesThe errors:Could it be that both sum.cpp and sum.asm compiled to sum.obj and this prevents the linker from properly linking the functions? (if this is the case, then why when changing .cpp file name doesn't solve the issue) « Last Edit: June 04, 2012, 05:21:52 PM by trismarck » Logged TightCoderEx Full Member Offline Posts: 103 Re: Visual Studio 2008 - "LNK2019: unresolved external symbol" error « Reply #1 on: June 04, 2012, 10:32:03 PM » As it was 7 yrs ago, I don't remember exactly how I solved that problem, but I seem to think undercoating _sum or decorating your declaration extern "C" int _sum(void) might solve the problem. Have a look in kernel32.inc and see how it's done there.

(I couldn't find the word in the dictionary)After adding the underscore in various places in the code, VS still yields an error.Also, I don't know if I'm looking on the right kernel32.inc file (I don't know what the file contains actually) (the kernel32.inc file from
