I created an empty C++ project in Visual Studio 2012 Express (for Desktop of course), and added some random basic code:

#include <cstdio>
#include <cstdlib>

typedef struct examplestruct
{
    unsigned char num1;
    unsigned short num2;
    unsigned long num3;
    unsigned long long num4;
} EXAMPLESTRUCT;

void examplefunction(unsigned long *num, int num2)
{
    *num += num2;
    return;
}

int main(int nArgs, char **pszArgs)
{
    EXAMPLESTRUCT ExStructInstance = {0xFF, 0xFFFF, 0xFFFFFFFF, 0xFFFFFFFFFFFFFFFF};
    printf("%d, %d, %u, %ull\n", ExStructInstance.num1, ExStructInstance.num2, ExStructInstance.num3, ExStructInstance.num4);
    unsigned long num5 = ExStructInstance.num1 + ExStructInstance.num2;
    printf("%d\n", num5);
    examplefunction(&num5, 10);
    printf("%d\n", num5);
    system("pause");
    return 0;
}

(If you’re wondering what the hell this is about, I’m disassembling the created executable file to observe the behaviour of the optimizing compiler, and also to learn more about x86 assembly.)

Under Linker in the project settings, I selected Multi-threaded (/MT) for the runtime library, so it would statically link it.

I compiled and started debugging with F5 and immediately got this error in a message box:

Runtime Error!

Program: C:\Users\xxxxx\Documents\P…

R6030

  • CRT not initialized

So, this basic program won’t run due to some problem with the runtime library, which I can’t figure out!

Any ideas? I’d just like to know what’s going on here. Thanks in advance!

EDIT: FYI, this is all done in Release mode.

    Start a new project with the “Empty project” template has a knack for causing trouble. You probably changed another project setting that causes your program to start at the main() method instead of the normal entry point, the CRT startup function. Which initializes the CRT, then calls main(). Hard to guess how you did it, especially when you talk about changing a linker setting to get /MT. That’s a compiler setting.

    Fall in the pit of success by using the Win32 + Win2 Console Application project template instead. Delete the pre-generated code, minus the #include <stdafx.h> line at the top. At the very least you’ll now have a starting point that can help us help you solve problems. And don’t skip the “Hello world” program.
