When I try to compile, I'm getting the following error message:

Any ideas?
GCC doesn't have constraints for registers %r8 .. %15. As D
doesn't have register variables either, you'll have to set-up r10
in the instruction string.
```
asm {
"mov %[rem], %%r10; syscall"
: "=a" (ret_code)
: "a" (230), "D" (clock), "S" (flags), "d" (req), [rem] "r"
(rem)
: "memory", "rcx", "r10", "r11";
}
```
