Heh, I used to use Borland C a long ago when he was in class. Anyway. I wrote a bunch of old games in text mode with the aid of conio.h. Well, now I use Dev-cpp 4.0 with MingW 1.0. I can't compile my old programs (though I'm really nostalgic about this! ) with dev-cpp because the included conio.h in the ming package doesn't have support for functions like gotoxy, getch, or clrscr(). I hadd some really simple oldschool text games (80 * 25, where I use cin and cout to do i/o, how cool is that?) and I just really would like to see them again. Is there another header that I can acquire to do things in textmode? Sure, I can simulate each gotoxy and a cout with a textprintf, and each getch with a keypressed(), etc. but that would be such a hassle. I just want to compile something :-p -Yan |

The problem is that the conio functions are a DOS-specific extension. You have basically two options: you can write a conio wrapper around a platform independent console library such as ncurses (my recommendation), which will make your code platform independent as well, or you can use DJGPP instead of MinGW, which includes Borland's DOS extensions. |

Hmm, I do use winXP now. But can you explain your last comment? It sounded mysterious :-p Meanwhile, the only free curses library I found was PDCurses. It comes with four builds, one for DJGPP, EMX, VC, and I think Watcom. Which one do I use? Do I use VC because its the most similar or something? -Yan |

DJGPP has a tendency to explode at random on Windows XP, for unknown reasons. -- |

You could be in luck with the Dev-C++ 4.0 distribution. Look in the Lib subdirectory of Dev-C++... there's a conio.o object file. Link to it, and a variety of old conio functions could/should/would work. I suspect the source, conio.c, is in the 'Include' subdirectory. Don't forget to look at conio.h. AFAIK conio.o doesn't come included with the Dev-c++ 4.9.x (5 beta) distribution, but there shouldn't be a reason one couldn't compile conio.c or perhaps use conio.o from the older distribution. |

The conio.h I see that came with dev-cpp only has like 10 functions, including getch. It won't however, do gotoxy or text-coloring, which my old thing does. Am I looking at the wrong one? And... an idea just popped up. I do have Borland lying somewhere (though I don't like to dig things back up really). Can I just use its conio, in some form? Or are they not compatible? If so, how? Thanks guys! -Yan |

Conio is a DOS terminal system. MinGW is a Windows compiler, but emulates some of the functions supported under DJGPP. Borland headers and libraries are not compatible with MinGW. As mentioned, your best choice would probably be to write a conio wrapper for curses and use that. -- |

Did you find conio.o and/or conio.c in the Dev-C++ 4.0 distribution? The gotoxy(), etc. functions are there. Give it a try. |

Ahh interesting. I found a conio.c that had the things like gotoxy, which was quite cool. But the conio.h in the same directory didn't. So even if I include conio.h and even conio.o under project options, they won't recognize gotoxy. That was kinda weird... any explanations / more help? -Yan |

I think its got to do with the windows console. It is basically there to dump stuff, and for backwards compatibility, and discusing it on another board, this person found that the WINDOWS console, not the compiler, did not support quite a few borland c function, including getch and stuff like that... basically if you want to do those old borland function, your best off doing them back in dos on good ol borland 3.1. .... actaully the new borland might somehow support all the old functions in windows, but ive never tried it. why dont you download it from borland.com and give it a shot? _________________________________________________ |

The other thing you could do is to port the stuff to Allegro, and use the Allegro textout, textprintf, etc. functions (since this is an Allegro forum, after all ---- |

Elbowing people in the ribs, winking broadly and saying "har har" has never made a bad joke funnier than the first time around And after M|B deletes MM's posts, this one can go in the trash too. -- |

I was able to use the functions in conio.c using MinGW 2.0, though MinGW 1.0 should work just as well. I did not include conio.h, taking advantage of implicit function declarations, though one could paste in function declarations from conio.c. I compiled my test program as a console program. And I linked with conio.o. The functions seem to work as advertised. |
