OpenBSD 6.1 termio.h: 没有那个文件或目录

Question

我尝试使用 OpenBSD 6.1 构建我的代码，但我收到此错误消息。

我该怎么办？代码用 Ubuntu 1604 编译。

<termio.h> header 不是标准的，尽管它在 Linux 上可用。标准的header是POSIX<termios.h>.

在我的 Ubuntu 16.04 LTS VM 映像中，文件完整包含：

/* 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   This is obsolete; use the POSIX.1 `struct termios' interface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>

如果您使用 non-standard headers，您可能不会在其他系统上找到它们。您可以使用上述信息为自己创建 <termio.h> 的副本。您可能很幸运，发现 BSD <sys/ioctl.h>（它确实存在）包含您需要的信息——如果有的话——但它不是 POSIX 标准化的 header，所以所有赌注都没有了.如果您只使用 <termios.h> 中的标准符号，您应该是安全的。
