如何在 Unix 上包含 «pty.h» 头文件/将 «pty.h» 添加到标准库 C / C++

How to include «pty.h» Header File on Unix / Add «pty.h» to Standard library C / C++

我想包含 pty.h,它通常在 Unix 上不可用(不包含在标准库中)。在网上可以得到相关的头文件内容。那么如何将这个头文件添加到标准库中,以便可以这样做:#include «pty.h»,而不是#include "pty.h" 谢谢

您可以将该文件复制到 usr/includeusr/local/include。 如果你 运行 gcc -v -E - (从 here 获得)你将得到以下输出
