openxdk compiling problems

schneidz · 02-27-2006, 08:53 PM

hi, i am trying to get this to compile:

Code:

#include <openxdk/openxdk.h>
#include <stdio.h>
#include <stdlib.h>

void XBoxStartup()
{
            char buffer[300]; // large temp text buffer
            sprintf(buffer,"hello-schneidz");
            vga_print(50, 50, buffer);
}

but i get more than 100 compiling errors from this using gcc in redhat 9.

Code:

[schneidz@hyper-nmv1so2wb hello-world]$ gcc -v

...

i get "cc1: invalid option `no-cygwin'" when trying to compile with '-mno-cygwin'.

does anybody have any experience with openxdk?

thank you,

you are using red hat linux to build this on?

Then you don't need the -mno-cygwin option.

But your program will fail compile anyway, as this warning message is saying:

Quote:

/usr/local/openxdk/include/xboxkrnl/dbg.h:17: warning: return type defaults to `int'

It comes from this line:

Quote:

void XBoxStartup()

C, and C++ must have a main function, so this should rightly be called main.
the other issue with it is the VOID. That is not a supported type for a function, it actually must be INT.

Code:

#include <openxdk/openxdk.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
    char buffer[300]; // large temp text buffer
    sprintf(buffer,"hello-schneidz");
    vga_print(50, 50, buffer);

  return 0;
}

is a functional format. I don't have the opendxk package to test it on, nor an xbox.

thanks much jaqui,

i was pretty sure i didn't need '-mno-cygwin' because i wasn't using cygwin but the confirmation is nice.

i was trying to do a slimmed down version of this:
http://www.xbdev.net/openxdk/tutoria...orld/index.php

i think my first problem is that 'xvga.h' isn't in '/usr/local/openxdk/i386-pc-xbox/include' or '/usr/local/openxdk/include'
(maybe it's only windows - is there a linux alternative?)

according to the tutorials i read 'XBoxStartup()' is the entry point for the xbox to run code.

what you said makes sense so i'll try to cross-compile it as a windows .exe then try to translate it to a xbox .xbe.

for a poc (proof of concept), can anyone get their xbox to say 'hello-world'.
