OpenBSD 6.1 termio.h：沒有這樣的文件或目錄

Question

我試圖用OpenBSD 6.1構建我的代碼，但是我得到了這個錯誤信息。

我該怎麼辦呢？代碼使用Ubuntu 1604編譯。

Answer 1

<termio.h>頭文件不是標準的，即使它在Linux上可用。標準標題是POSIX <termios.h>。

在我的Ubuntu 16.04 LTS的VM映像，該文件包含在其整體：

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    This is obsolete; use the POSIX.1 `struct termios' interface 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

如果您使用非標準的頭，你可以期望沒有找到他們在其他系統上。您可以使用上述信息爲您自己創建<termio.h>的副本。您可能很幸運，發現BSD <sys/ioctl.h>（它確實存在）包含您需要的信息 - 如果有的話 - 但它不是POSIX標準的頭文件，因此所有投注都關閉。如果您只使用<termios.h>的標準符號，則應該安全。
