Thread: DevC++ accepts neither "conio.h" nor "conio.c"

Hi,

I can't seem to compile the following program:

Code:

#include <stdio.h>
#include <conio.h>

int main()
{
   textbackground(4);
   clrscr();
   cprintf( "THE BACKGROUND IS RED BUT TEXT IS NORMAL WHITE" );
   getch();
   return 0;
}

under DevC++ 5 even if i change conio.h to conio.c.

When compiling using conio.h error is:
[Linker error] undefined reference to `textbackground'
[Linker error] undefined reference to `clrscr'
[Linker error] undefined reference to `cprintf'

When using conio.c:

Your prog works fine for me. I am use borland. The unresolved externals might be because your .cfg file is not there?

Do other progs compile for you?

Because conio.h is not part of the C standard. It is a Borland extension, and works only with Borland compilers (and perhaps some other commercial compilers). Dev-C++ uses GCC, the GNU Compiler Collection, as it's compiler. GCC is originally a UNIX compiler, and aims for portability and standards-compliance.

If really can't live without them, you can use Borland functions this way:
Include conio.h to your source, and add C:\Dev-C++\Lib\conio.o to "Linker Options" in Project Options (where C:\Dev-C++ is where you installed Dev-C++).
Please note that conio support is far from perfect. I only wrote it very quickly

Meow sorryz.

Now i'm forced to switch back to DevC++ 4. But i still want to figure out the problem. I really want to find out if any other DevC++ 5 users have the same problem. Or someone else got any ideas?

thnx
