Using BSD and pty functions C++ Project

[HiMK]

Hello

I have a weird error occurring, where if I use the function `openpty()` in C program it compiles ok but if I have the exact same code in a C++ program I get a compiler error:

error: 'openpty' was not declared in this scope

Both Xcode projects have the exact same code in one file (main.c and main.cpp respectively).

How can I fix this error?

Code:

   #include <stdio.h>
    #include <stdlib.h>
    #include <errno.h>
    #include <fcntl.h>
    #include <sys/stat.h> 
    #include <termios.h>
    #include <unistd.h>
    #include <sys/types.h>
    #include <sys/time.h>
    #include <sys/select.h>
    #include <string.h>
    #include <pty.h> //  error: pty.h: No such file or directory

    int main (int argc, const char * argv[]) {
        int gps_fdm, gps_fds;
        char slave_port_name[256];
        int open_res = openpty(&gps_fdm, &gps_fds, slave_port_name, NULL, NULL); // compiler error here
        return 0;
    }

It might complain for C as well if you use -Wmissing-prototypes as a compiler flag.

Yeah, this is the real problem.

You need to find whatever package pty.h this comes in and install it.

Don't forget to set your include paths--the directories where the compiler looks for these header files. How you do that depends on your compiler/IDE.
