>Sorry for waiting until now to reply. It's all good. : ) >What do you think? I think we should convert to BE, but not away from PE-COFF. There are too many differences between them, and while it would be less work in the short term to switch to ELF, in the long term, implementing all of the features of PE would be very troublesome. Not the least concern is that information such as import data and file headers aren't even mapped into a process's address space with ELF. As I understand it, when you get an IHANDLE to a linked in DLL it's just a pointer to the mapped in PE file header. I'm sure there are programs that require this on a source level to run (which, for quite some time will be the only thing that affects us on the PowerPC side of things). That being said, a proper pe-powerpcbe target in gcc should then be the first priority. Binutils already more or less properly creates pe-powercbe files (with what I assume are your patches on the wiki, and a little monkeying to make sure that the MZ header and PE signature are always written as little-endian regardless of the target architecture). What kind of issues had you had on the EABI side of things, and what was your plan in more detail for emulating the features of PE in ELF? Also how much progress had you made in the port up to now? ~Tristan Miller (monocasa)

Interest in ReactOS and some requets
by Arko Provo Mukherjee 13 Mar '07

13 Mar '07

Dear friends, We are 3 undergrad comp sc. and IT students from India. We have some coding experience but have never worked for the Open Source Community as developers. Yet we have always admired the concept and used FLOSS stuff like GNU/Linux. We came across ReactOS project and got really interested in it. We really want to contribute to the development of React OS and since we are new in Open Source development, we would require your guidance and support in stuff like understanding the code, building the build environment etc. Among other shortfalls that we have, we haven't programmed much on Windows platform (almost always Linux ie) and hence know little about the Windows API. But we are eager to learn and can definitely learn parts of the API as long as you can guide us. We humbly request you to guide us and give us some problems so that we can try and support this community. A lot is left to be done in ReactOS and it would be great being a part of such a project. Also we are better at writing C codes than reading them ( like almost everyone ;) ) and hence would request you to give us some problems that we can write from stratch rather than bug fixing that would require reading all codes. But we are ready to contribute in any way you feel we can as developers and support this community. Regards Arko Provo Mukherjee Abhishek Biswas Biswanath Banik

How can I help?
by Sam Banks 11 Mar '07

11 Mar '07

Hi Guys I have recently discovered ReactOS through my research for Linuxforums.org, I have written an article on ReactOS, which should show up online in the near future. Basically I like your work and I would be keen to contribute some of my (unfortunately limited) time and skills to your project. I cant code but I can write ok. Could I be of any use to you guys? Cheers Sam -- Did you know that if you play a Windows XP cd backwards, you will hear the voice of Satan? That's nothing! If you play it forward, it'll install Windows XP.

Endianess

Hey, Sorry, having problems with internet or else I'd ask this on IRC. I was curious as to why the emphasis on little-endian mode in powerpc. Mac G5's don't even have le-mode, and it definitely seems that (although im not totally sure, as theres not much info out in the wild yet) that the XBox360 lacks le-mode as well. Also, on the processors that support le-mode, it seems in all cases (although theres probably some embedded guy that I'm missing : P) that do support it, it's selectable at the minimum at the user/supervisor level with only a bit of work. Perhaps eventually a thunking layer (maybe a part of NTVDM, would it need to be that complex?) that would translate the calls from le usermode to a be kernel could be written, allowing one to run NT-PPC applications that are out there. We wouldn't be able to load drivers (or any le kernel code), but are there actually any PPC drivers out in the wild? Plus, it seems that it would definitely be a good thing for the kernel source to be tested on multiple endians as early as possible in its development to ease porting later on. ~ Tristan Miller (monocasa)

Re: [ros-dev] [ros-diffs] [ion] 26032: - Tree cleanups proposed on the mailing list. Move all non-Core OS modules to rosapps. Tests were already moved by Fireball to rostests.
by Aleksey Bragin 11 Mar '07

11 Mar '07

It's all about re-thinking what rosapps is. Initially it was supposed to be a place for various "app"lications. Right now it turned out to become a kind of a trashcan, where stuff unapplicable for trunk goes. Since this is wrong, it's perfectly fine to "force" devs to build with rosapps (and rostests, if they are interested in thorough testing) module. Otherwise, with make/make all, we again end up with rudimentary rosapps. Also there will be some kind of "unmaintained" module (undecided yet - discussions are welcome) where some stuff from rosapps is going to be moved (which is not currently maintained, and not interesting for devs).

Hi, yes definately. Our project would certainly benefit from a good PR and spread the word, because it eventually brings new developers and thus development speed rises. Thanks a lot, and feel free to email here or me. With the best regards, Aleksey Bragin.

Move all non-Core OS modules to rosapps. Tests were already moved by Fireball to rostests. > This will break 'make bootcd' Upon thinking about this, I'm not sure it's such a good idea with respect to usermode stability as it will get less testing now from non-included apps. Another idea, instead of moving everything out of the main trunk would be to give each component a new tag in rbuild. This tag could be something like core="yes|no". Everything which has been moved to rosapps could be labeled with a core="no" 2 new build commands would be available, make core and make corebootcd. This would allow us to have the best of both world. Many of the tests we run at application level rely on the apps which have just been moved being easily accessable. If these are gone, I suspect less feedback will be collected about the status of usermode. Ged.

I forgot to mention that I used Ged Murphy's .ppt as a base (design mostly), and I used some parts of information about the kernel given by Alex Ionescu. WBR, Aleksey Bragin.

Setting autoreply while being subscribed to a mailing list - that's something not good to do. Unsubscribed... WBR, Aleksey Bragin.

Hi, thanks for your interest. Yes, Arty is indeed The Man to contact regarding the PPC port, but anyway post your questions here if you can't catch him on irc, and they will be answered sooner or later. WBR, Aleksey Bragin.
