Very Computer

Hello All,
I have Redhat Linux 5.4 up and running fine and I am using gcc v
2.7.3.1 I think it is. I am doing a Open University course in my
spare time, which involves learning the C programming language under
MSDOS. So I thought this was the time to use the Linux programming
resources that I have, and program under Linux. However, I am having
great difficulty compiling and running even the most simple msdos C
programs under Linux! I am using a ANSI C compiler under MSDOS and it
compiles, links and executes all the programs really easy, without
having to have the use of any include libraries, which come with the
msdos compiler.
      When I do attempt to compile under gcc I keep error messages,
saying that the reserved C words are not recognised. So the program
will not compile, let alone link, and let alone run! Any help would
be greatly appreciated.

However two possibilities do come to mind
  a) you have a dual boot system and you have ended up with an upper
     case file name which will be interperted as C++, not C source
     (because it ends in .C rather than .c - these things matter to
     Unix systems).

  b) You have just learnt that C isn't actually terribly portable
     and gcc has got upset with DOS specific constructs

Post a (small) code snippet and people may be able to help.

Do your programs include headers like <dos.h>, <io.h> or <conio.h>?

Do you call functions like getch() or cprintf()?

None of these features are part of ANSI C.

What rubs me the wrong way is that they are learning obsolete MS-DOS
extensions that won't compile elsewhere.

What an utter waste of time.

But hey, what else is an unemployed DOS programmer gonna do? Teaching his
obsolete skills to a new breed of disciples could be a good way of
refurbishing a deflated ego. :)
