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:

=20

undefined reference to _disable, _enable.=20

=20

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,

#include <stdio.h>
#include <stdlib.h>
#include <intrin.h>
int main()
{
    _disable();
    printf("Hello world!\n");
    _enable();
    return 0;
}
