conio.h for Windows but not for Linux?

[americast]

Hi all,
  I have found that the windows version of code::blocks supports the header file <conio.h> and its functions (like getch() etc.). I have also installed a copy in my Linux distro (OpenSUSE 13.1) with GNU GCC G++ (C++) compiler which does not offer support for the same. Is it possible to incorporate conio.h into Linux? This is because some of the programs using conio.h is not working on my Linux system...

You may find why it's not working on GNU / Linux here:

conio.h

Thanx...
So, how do I get such functions working on my linux system? Is there any alternative? Functions such as getch() and kbhit() are really quite useful...

You should get yourself a C book, preferably an ANSI C one, and learn more about libraries like stdio.h.

For instance, http://pubs.opengroup.org/onlinepubs/009695399/basedefs/stdio.h.html explains things like getchar() and putchar() that do what you want to accomplish that also is POSIX compliant, therefore portable by standard.

Is it possible to integrate mingw compiler with code blocks in linux?

for cross compiling windows programs on linux with mingw? For sure! But you wouldn't be able to run them on linux natively... only with the help of wine.

You can also install & use ncurses library.

I have used this as a replacement for the windows _getch.
You will need to include term.h on Linux.
Be aware, I understand there are problems with term.h inclusion and g++ ????

  new_settings.c_cc[VMIN] = waitkey;
  new_settings.c_cc[VTIME] = 0;
  tcsetattr(0, TCSANOW, &new_settings);

    //read(0,&ch,1);
    ch = getchar();
  tcsetattr(0, TCSANOW, &initial_settings);
  return ch;
}

I have got the ncurses library. Simply using #include <ncurses.h> does not work. Should I include only curses.h to get getch() working?

I am getting an error in the first line (struct termios initial_settings, new_settings;"):
