Include termios.h instead of termio.h

[luveti]

termio.h was removed from glibc in version 2.42 (released in July 2025)

[stappersg]

Now waiting for confirmation.

(It other words: This merge request waits for works for me)

Can't run tty0tty because there is no termio.h library in system. Have no idea how to launch it

[krokosik]

The fix does half the job, it also needs to be applied in module

Once I changed:

sed -i 's|<termio.h>|<linux/termios.h>|' module/tty0tty.c
sed -i 's|<termio.h>|<termios.h>|' pts/tty0tty.c

The program successfully compiles and runs on CachyOS with 6.19 kernel.

@krokosik I do not see termio.h being imported in https://github.com/freemed/tty0tty/blob/master/module/tty0tty.c. Maybe it was included in an older version, or by a patch CachyOS/Arch/pacman is applying?

[krokosik]

Huh, indeed. The AUR package seems to use a different repo? https://github.com/lcgamboa/tty0tty
Does anyone know what's the difference?

It looks like https://github.com/lcgamboa/tty0tty was created by the original author https://sourceforge.net/projects/tty0tty/
