Graphics without a library?

[brentc628]

How could one go about generating graphics in C or C++ without a library?

I have tried mode 13h, and my compiler (Dev-C++) always gives me error messages.

And if anybody wants to answer this too, I can't seem to run my programs in MS-DOS
(Yes, I'm trying to use MS-DOS), I know that programs compiled in windows tend
to work only in windows but is there a way I can convert them, or a compiler that can make .EXE's that are meant FOR MS-DOS?

Any help?

[brentc628]

Oh, yeah I forgot.

I've tried Pacific C compiler, Turbo C, and DJGPP, and none of them have worked for me (Pacific C works a little, but it doesn't compile correctly most times).

And I also wanted to mention I am DEFINITELY not new to C++ (Although I am not as well versed in C) I just haven't gotten around to graphics yet.

Most console applications should run under MS-DOS. You should have no problems create a console app to run in DOS.

Is this for a game?

[brentc628]

I want to make a custom interface (It's something I've been pretty good at in the past).

And it would be nice to make a few games on the side (Which I'm also Pretty good at).

I tried creating a console APP, but when I try to run it in MS-DOS, it says that it cannot be run in console mode.

I managed to get Pacific C to create a console APP for MS-DOS, but it won't compile much more than a Hello World.

Then my guess is you'd have to develop it in DOS. And use a DOS compiler. This would because of the OS linked files that would need to be compiled in. (Similar to doing it on Windows and Linux).

[brentc628]

Thats one of my problems, I've tried to compile it in DOS but none of the compilers that are for DOS will work right.

[Zaita]

Are any of the DOS compilers updated still? They maybe using Pre C++98 standards.

[brentc628]

They're fairly recent, not brand new or anything, but they shouldn't be out of date enough not to work.

Have you tried Open Watcom^[1]

Host Platforms
Win32 systems (IDE and command line)
32-bit OS/2 (IDE and command line)
DOS (command line)
Windows 3.x (IDE)

Target Platforms
DOS (16-bit)
Windows 3.x (16-bit)
OS/2 1.x (16-bit)
Extended DOS
Win32s
Windows 95/98/Me
Windows NT/2000/XP
32-bit OS/2
Novell NLMs

Watcom used to be very good prior to it going open source, that not to say it is not good now, I haven't used it since it was 'opened'.

As yet,I haven't hear of any complier which satified your requirement！
But you can try the "ASCII Art",although it is not the reallly graph!

[brentc628]

I've managed to get lucky and find a compiler.
It was actually found while I was looking up some stuff about QBasic.

For anybody else who wants these basic functions, it's called FreeBasic, it was originally a Basic compiler, but they've added capability to use C functions and C libraries in it.

You could call it a C compiler with Basic functions attached (Basic has graphics capabilities). It even has mouse functions. With no external libraries needed for the Graphics/Mouse capabilities.

thanks for the help though!

P.S. -- OpenWatcom didn't work either, it would always say that it couldn't be run in DOS mode.
