Conio.h not working in codeblocks (Undefined reference to ..) - c

Question

I'm working with Code::Blocks and the thing is I tried many times to fix the problem with the Conio library and probably some other libraries as well. Every time I use something like clrscr(); textcolor(); or anything it says ;
Undefined reference to textcolor.
For example, this simple program is supposed to show the sum in a specific color but it's not working out though I have seen it work before.
#include <stdio.h>
#include <conio.h>
int fx(int x,int y,int z)
{
return x+y+z;
}
int main()
{
int a,b,c;
printf("Enter three values to a, b and c.\n");
scanf("%d%d%d",&a,&b,&c);
int total=fx(a,b,c);
textcolor(14);
printf("Output ="); cprintf(" %d",&total);
getch();
return 0;
}
P.S.: I'm using GNU GCC. And sometimes when I select another compiler or just open Code::Blocks it says, "Some plugins are missing," or something like that.
Can anyone help??

Answer 1

conio.h is not supported with gcc.

Answer 2

conio.h is not supported by gcc. Here is an implementation of conio.h for gcc though.

Answer 3

conio.h is not supported in gcc. You may try the curses library, which supports creation of text-user interface.
There are many flavor of curses, you may use ncurses or pdcurses library with code-blocks.

Some of the functions in the original Borland conio.h are easy to duplicate -- I've recently been porting from Turbo-C programs (from 1990!) to gcc, and found versions of getch and getche (for Linux) that I could use online (but not the C++ version, which won't compile using the gcc command). I wrote my own version of cgets, but haven't found the need to create my own versions of the other functions from that header file yet.
char getch()
{
char c; // This function should return the keystroke without allowing it to echo on screen
system("stty raw"); // Raw input - wait for only a single keystroke
system("stty -echo"); // Echo off
c = getchar();
system("stty cooked"); // Cooked input - reset
system("stty echo"); // Echo on - Reset
return c;
}
char getche()
{
char c; // This function should return the keystroke, with echo to screen
system ("stty raw"); // Raw input - wait for only a single keystroke
c = getchar();
system ("stty cooked"); // Cooked input - reset
return c;
}
char *cgets(char *buf)
/* gets a string from console and stores it in *buf; buf[0] must be initialized to maximum string size and *buf must
be declared by caller to maximum string size plus 3 bytes, to accommodate string, terminating null, size byte in buf[0]
and length of entered string in buf[1]; sets buf[1] to length of string entered and returns pointer to buf[2] */
{
/* declare and initialize internal variables */
unsigned int count = 2; /* start at 2 because [0] is max size including terminator and [1] returns actual */
/* entry size, also including terminating null */
char input = '\0'; /* initialize to null */
/* start actual function */
while (count < buf[0] + 2) /* while within permitted string length -- +2 for size control bytes */
{
input=getch(); /* get a single character, without echo */
if (input != (char) 13) /* not cr/enter key -- presumed meaningful input */
{
printf("%c",input);
buf[count++] = input; /* store character and increment counter */
}
else
{
buf[count] = '\0'; /* change cr/enter key to terminating null */
buf[1]=(char) count - 2;/* store length of entered string (including terminating null) */
count = buf[0] + 2; /* terminate entry loop -- +2 for size control again */
}
}
return &buf[2]; /* return pointer to start of string */
}
The key thing to remember is that an included file (such as conio.h) doesn't have to be precompiled; it can be just as functional if it's just more C source code.

Try this library: https://sourceforge.net/projects/coniohcloneturboccpp/.
The CONIO features for Windows and Linux are almost complete. It seems to work well.
