Hi Tim, I'll have a go at hosting CVS if you like, I've yet to determine what my cable connection is like for such things so I'll stick a recent patch of xfractint in and set you and Jon up with accounts on my cygwin setup so you can use ssh to access the repository. I've also written up some quick howto's for the other UTron project coders so I'll post them as well. Probably get it done over the weekend, watch this space :-) >On another subject, what is the problem re Fractint and XP? Probably the same as with NT and win2K, they all use a HAL type setup so direct hardware access is out. Though 2K and XP can both use directx. I wonder if any windows whizz out there could do a directx wrapper in fractint for video and keyboard access, that'd be cool :-) Cheers, Robin. ------------------------------------------------- This mail sent through UK Online webmail

Tim, > I have looked into using indent. It's fine for new development or > situations when you are willing to redo all the comments.

I used it on video.c and the comments were virtually untouched. I like the results. As expected, the file size increased (from 16216 bytes to 17049 bytes). Don't try this at home, I have already modified the file to clear up the -Wall warnings. Unfortunately, the object file size also increased (from 49984 bytes to 50080 bytes). Not much, but I'm a little uneasy about it. I looked at the before and after C files and couldn't see any obvious reason for the different object file sizes. Jonathan

Hi Folks, Just to let you know I've checked in the fractint and xfractint source to my cvs box, including all the patches from V20.0 to now. If you want access then drop me a line and I'll set you up. Cheers, Robin. ------------------------------------------------- This mail sent through UK Online webmail

Tim, > On another subject, what is the problem re Fractint and XP? Not having tried it, my guess would be that since it's based on NT it doesn't have suitable video drivers. And, there is some question about DOS compatibility of XP. I don't recall what this means, but it sounded to me like it means Fractint won't ever work in its present form. Jonathan

wishlist and buglist

Hi Jon, >Would it be possible to edit some of the inane >comments out of the Fractint >bug list and wish list? Certainly, it has been getting a bit cluttered lately, some people seem to think the buglist is a place to report *any* bugs with windows! better get that idea quashed real soon or we're going to be snowed right under :-) I'll add in some stuff about win2k /XP too like you asked for recently. Great work getting some ASM code going under xfractint BTW, Thanks! I've got a laptop all set up with debian gnu/linux and have got xfractint compiling now so I'll see if I can get my old dxf output patch in to warm up. Sorry about the long pause in fractint work but I've been busy getting an object oriented head on by trying some UnrealScript coding... anyone remember Tron? http://www.planetunreal.com/utron :-) I'm also getting familiar with CVS and have my own server hanging off a cable modem now and I'll see if I can't get xfractint checked in for us to play with if you like (though ISTR Damien may have CVS on julia already which might be a better option) Merry Xmas to everyone and have a great new year! Cheers, Robin. ------------------------------------------------- This mail sent through UK Online webmail

Fractint bug list and wish list

Robin, Would it be possible to edit some of the inane comments out of the Fractint bug list and wish list? That might reduce the occurrence of more of it. Thanks. Jonathan

Windows XP

Tim, It looks like we should update the bug list and wish list screens to explain why Fractint will never run on Windows XP. At least not until several lengthy projects have been completed (or started). Jonathan

Humberto, > I may be completely off the mark here, but some optimizations involve code > unrolling and duplication so this could be the case for the object size. And > I assume you're talking about the stripped binary in both cases. The optimizations were the same in both cases. But, I didn't do anything with the binaries, so maybe that's the problem. > And by the way why are you worried about the code size increase in > xfractint? I'm only worried about the size increase because it may indicate a change in the logic of the code run through indent. Jonathan

Xfractint compiler optimizations
by Jonathan Osuch 18 Dec '01

Tim, Did you know that the Xfractint Make file does not have any compiler optimizations set? Setting -O2 works wonders. The down side is that it breaks the assembler mandelbrot code. I'll have to look into that. We also don't set any CPU specific optimizations. This is probably a good thing, but it would also increase the execution speed. Duh! I've decided to start seriously working on dumping my Windows environments. I'm presently looking into dosemu. Although, if I can't get that to work correctly, I'll set up a boot to DOS instead of to the GUI so I can still work with Fractint. The major problem I have is that I'll need to purchase a new external DSL modem (a Cisco 673 or 678?). I have an internal PCI DSL modem at present, which isn't supported by Linux. Jonathan
