Title: New Release Of Openxdk
Post by: edwardaux on October 04, 2004, 04:41:00 PM
After a long hibernation, OpenXDK has finally released some more code containing a number of fairly major changes.  Highlights include:

- Migration to a GCC-based toolchain.  It now compiles using the Cygwin GCC compiler.  Unfortunately, as much as it would have been desirable to support both MS and GNU toolchains, the practicalities are such that the MS compilers are no longer supported.  Sorry!  (Although, theoretically, you should be able to compile your application using the MS compilers and link in the GCC-compiled OpenXDK libraries.)

- It now contains a complete libc replacement (thanks to newlib.)  This means that 99% of the normal stdio, memory, sprintf, et al routines are available.

- Multimedia support is provided using the Simple DirectMedia Layer (SDL) and supports video, joysticks and event handling.  Video is currently limited to 640x480 or smaller.  Only one joystick/pad is supported (but that is expected to be fixed soon.)

- To demonstrate the capabilities of the current OpenXDK framework, the SDL port of Doom (without sound or networking) is able to be compiled and executed.  You will need to find a DOOM1.WAD (shareware) and put it in the root of your XBOX's C drive.

- Sound and networking are currently not supported.  If you have experience in interfacing with the NVidia nForce MCP-D chip at the hardware/driver level, please get involved!

Head on over to http://openxdk.sourceforge.net to check out the latest code.  Or pay a quick visit to http://www.openxdk.org for the current documentation.

Have you seen/looked into free-xdk ?  Maybe could use for some input or img libs.

wonderful!  a great step forward in the xbox homebrew scene. Hopefully OpenXDK will open avenues not thought of before smile.gif

Cheers!

I think I speak for all linux developers out there when I say:

oh. my. god

I've always hoped that one day I could gcc together an xbox app/game, and the day has come.  Wow.  Freaking awesome.


Thank you.

Actually, it doesnt look like there's anything here that wasnt in free-xdk already.

I dont recall ever once seeing any of the free-xdk development milestones on x-s news....

All well, that's quite in the past now, I guess.

P.S.

Remember that uber-rad intro animation in the first PBL?  Yah, that has to be some of my finer work....

Ah, memories.

Nice to see some progress here again...

Is it possible to eventually replace the xdk completly... or is directX (due to copyrights) impossible to impliment?

Artifex
if your going to say something dont beat around the bush... say 'why does x-s not post milestones of free-xdk'
Did you submit the news? no? hrm

? your PBL has to do with?

sry but the tone of your post is annoying...

I rather people say what they want to say rather than

<semi complaint here>

<lookie im a old scener respect what i say here>

No flames... just curious why you dont post what you think in plain english rather then under the table political crap
that sir is what ruins the scene

W0W.... I thought that the OpenXDK project was lost... guess not...

Caustik must be trying to get cxbx towards a more versatile app.....

wow,now that the OpenXDK has SDL implemented (even though there's missing sound support),i think i should start converting my SDL-ports :-) . This is really great news !

maybe its time Free-XDK made a 0.1 release as opposed to solely CVS?

either way there are some extremely talented hackers out there.. gg to the devs

Is it possible to compile pbl-meetoo or any dashboard with this now... if yes wouldn't it mean that it is completly legal to softmod an xbox....

Shit, why haven't I heard anything.
Have you guys not been telling X-S?

Why arn't you working together on this it is so important that we have a free legal XDK on the xbox.

Here here, has anyone tried to compile one of these, or better yet, has anyone trried to compile XBMC or Avalaunch with this. How about trying to compile the Mouse test app with this.


HELL! Y don't I try it. Where can I download!? ph34r.gif Dang, I don't have linux on my system  sad.gif  (wish I'd bought that 250GB drive and installed dual systems like I started to). Guess I'll have to try linking the files.

Wish it had some instructions so I knew what I was doing!

Open-xdk does not let you recompile normal MS xdk written apps (dashboards, graphics tests etc.).  It does not provide the same API as the normal xbox libs, and doesn't support 3d graphics at all (nor does it support 2d-accelerated graphics?).

This is not meant to downplay open-xdk at all, it is just a response to the sorts of comments like "Can you recompile evox now?"

It DOES allow people to write completely new applications and to port some SDL apps.  Someone could fairly easily write a dashboard using open-xdk now.  Which would be pretty cool.  Looks like open-xdk is still in a bit of fledgling state though, but I'm sure it will improve now that someone has gotten more interest in it.

P.S.  Looks like I'm one of the oldest xbox-scene members there is.  Doesn't that count for something? smile.gif

Funny, your sourceforge page is slashdotted and the project page shows.. 0% completed, 0 released files.

oh! oh! www.freexdk.com.. no..wait.. that's parked at godaddy.

oh lets google search it.  Bunch of links to the beforementioned sf page and others not particularily related.

Maybe if you had released some information regarding free-xdk hitting milestones instead of just quiet cvs updates, hell, even a released file now and then... or a website.. or a percentage complete.. then someone would have taken notice.

I saw some questions about trying to compile XBMC, et al, so thought I would post a quick update on what you can and can't do with OpenXDK.

- OpenXDK does not (and probably never will have) have the same API as the official XDK.  The MS XDK is heavily based on DirectX, which I do not have the source code for, so I have to use something else.  

- SDL (http://www.libsdl.org) is what I have chosen to base OpenXDK multimedia capabilities on.  It has video, audio, joystick, events, threads, file, networking support as part of its API (note that only video, joystick and events have been implemented so far in OpenXDK, but that will change over time)

- I have only tested using Cygwin GCC on Windows 2000.  I have *not* tested on Linux.  However, having said that, I don't believe that it will be a huge step to move to being able to compile on Linux.

- The OpenXDK compilation process produces i386 Portable Executable (PE) files.  These are Win32 applications that are post-processed by a utility called CXBE to convert to an XBE. To compile under Linux, you will need a GCC cross-compiler that produces i386 PE executables (not ELF).  You will then need to run a Linux version of Caustik's CXBE to convert to an XBE (I have already received an email from someone who says they have ported CXBE to compile/run under Linux)

- OpenXDK does not currently have audio, networking or usb support (the first two are my number 1 priority)

- I am currently in the middle of integrating code that will allow OpenXDK to launch other XBE files.  This functionality combined with the existing SDL capabilities should be enough to write an open dashboard.

- Lastly, please bear in mind that OpenXDK is a work in progress.  It is missing some functionality, but it also has a bunch of good features that mean it is getting closer to being suitable for real XBOX development.

To read about some of the existing functionality, have a quick look at http://www.openxdk.org

Anyway, I hope that helps clear up some of the confusion.
