I cannot use termios.h in cygwin64

I am making an application where I think I will need to use termios.h But I have windows 10. I installed cygwin64. I type in gcc test.c -o test.exe in the terminal. I still get fatal error: termios.h: No such file or directory #include <termios.h> Is there something I had to do during installation?

The code is just prints hello world but I included termios.h

#include <stdio.h>
#include <termios.h>

int main(){
     printf("Hello World!");

     return 0;
}
Solution

  • Install the missing development package. To find which is, use cygcheck

    $ cygcheck -p usr/include/termios.h
Found 12 matches for usr/include/termios.h
cygwin-devel-3.0.7-1 - cygwin-devel: Core development files
...
cygwin-devel-3.2.0-0.1 - cygwin-devel: Core development files
cygwin-devel-3.2.0-1 - cygwin-devel: Core development files
...

    You need cygwin-devel

    $ cygcheck -l cygwin-devel |grep termios.h
/usr/include/termios.h
/usr/include/machine/termios.h
/usr/include/sys/termios.h

    looking at your example

    $ cat prova.c
#include <stdio.h>
#include <termios.h>

int main(){
     printf("Hello World!");

     return 0;
}

    and at the compiler

    $ which gcc
/usr/bin/gcc
$ gcc --version
gcc (GCC) 10.2.0

    the example builds fine

    $ gcc -Wall prova.c -o prova
$ ./prova
Hello World!
