I am working on a project which calls _disable and _enable interrupt built in functions in the Windows environment. I can build the code with /Oi flag with Microsoft Visual Studio, but failed with gcc compiler with link errors:

 

undefined reference to _disable, _enable. 

 

I have code included, very simple. I am not sure what the problem is, maybe I should link with a specific library. Please advise.

 

Regards,

int main()
{
    _disable();
    printf("Hello world!\n");
    _enable();
    return 0;
}
