OpenBSD 6.1 termio.h: No such file or directory

Question

I try to build my code with OpenBSD 6.1 but I get this error message.

What can I do about it? The code compiles with Ubuntu 1604.

The <termio.h> header is not standard, even though it is available on Linux. The standard header is POSIX <termios.h>.

On my Ubuntu 16.04 LTS VM image, the file contains, in its entirety:

/* Compatible <termio.h> for old `struct termio' ioctl interface.
   This is obsolete; use the POSIX.1 `struct termios' interface
   defined in <termios.h> instead.  */

#include <termios.h>
#include <sys/ioctl.h>

If you use non-standard headers, you can expect not to find them on other systems. You can create yourself a copy of <termio.h> using the information above. You may be lucky and find that the BSD <sys/ioctl.h> (it does exist) contains the information you need — if any — but it is not a header standardized by POSIX so all bets are off. If you're only using standard symbols from <termios.h>, you should be safe.
