C Code without official includes

Hi coders.

How would I go about doing a basic Hello world with out using the official includes, is there a way to do it like you can in Assembler? Putting all the system calls in a different header file or at the top of the source, so other people can compile it with the freeware version of Dice.

OpenLibrary(),CloseLibrary(),Output(),Write() ??

Any tips would be much apreciated.

I would like to be able to call different ROM functions via C, I know it can be easily done with Assembler, just wondering if it's just as easy with C.

The official includes are as free as Dice is. Why would you want to omit them?

Dice: http://aminet.net/dev/c/dice-3.16.lha
Includes: http://www.haage-partner.de/download/AmigaOS/NDK39.lha


lha -xa x dice-3.16.lha work:dice-rel-3.16/
lha -xa x NDK39.lha work:
put this into s:user-startup:

assign DCC: Work:dice-rel-3.16
assign DLIB: DCC:dlib
assign DINCLUDE: DCC:include
path DCC:abin add
set DCCOPTS -// -proto -3.9 -D__USE_SYSBASE
;END Dice C
and reboot.

Then either

copy work:NDK_3.9/Include/include_h dinclude:amiga39 all clone

makelink dinclude:amiga39 work:NDK_3.9/Include/include_h force
if your file system supports this.

Then clean up the Dice includes like this:

cd dinclude:
list ~(amiga39) all files lformat="if exists amiga39/%p%n*n delete %p%n*nendif" >ram:qqq
execute ram:qqq


cd dlib:
copy work:NDK_3.9/Include/linker_libs/amiga.lib amiga39l.lib
libtos amiga39l.lib amiga39s.lib

Test program:

#include <proto/dos.h>

int main (void)

Printf ("Hello World\n");
return (RETURN_OK);
compile with

dcc hello.c -o hello
