    Problem With Official Devkit And Windows Xp

    Sorry, hyjacking your thread a bit. ;) But i'm a bit confused, why is the official sdk using cygwin where as the sdk in the archives is not? Seems to be an added layer to go wrong. Could they not just use the arm gcc that runs on win32?

    Clipping, How To? (stuck On Tri's)

    Ok, i've got my clipping working but it seems to create too many triangles. Is this to be expected? Here is the updated app + code The code is not optimal its mainly done to make it readable. I'm more intrested in optimising the algo before optimising the code. The later can be done when i'm...

    Problem With Official Devkit And Windows Xp

    Thats odd, have you checked your paths? Has your windows account got Administrator rights? Maybe thier sdk does not install correctly if you don't. (straw clutch)

    GP2X Gp2x Development

    You should give the Visual studio 2005 route a try and grab the sdk thats in the gp32x.de archives. This is what I use and I feel for a previous games coder is the easiest to pick up.

    Clipping, How To? (stuck On Tri's)

    rixed, would I expect that my final code will need to subit created tris against planes yet to test? Mmm, i've got a feeling thats an obvious yes. From your code I think the method is... start with zero points in the output data and the three in the input tri. do trival accept or reject else...

    GP2X Dangerous Linux Hacking Code

    Ah, I think I get it, still a bit new at this Linux lark. Sorry, a bit offtopic, but if the gp2x was using Linux in the normal way I would be logged in as a normal user and this 'hack' would fail? (Guess this is why Windows has problems as most login as administrator letting naughty progs to...

    GP2X Dangerous Linux Hacking Code

    Am I correct in saying this has no effect to the amount of memory avalible on the heap? All it does is change the cache mode to the upper 32megs? So to use this mem in an emulator your still need to manage it your self, but at least its at full speed now? :) Very cleaver mate! But is it not a...

    Clipping, How To? (stuck On Tri's)

    Yer, sorry was in a rush when I posted. Had to walk the dog and do the shopping before the football started. :) When you run the app up your see one line and a triangle. The line is testing my line code, which is working a treat. The read part shows the resulting line after clipping. All the...

    GP2X Networking Toolkit: Waste Of Time?

    I'll answer with a question, would you enjoy coding it? If so do it, its as simple as that. I'm doing a 3D engine and i'm sure its not needed that badly as there are other 3D engines in development. I'm doing it because I enjoy coding it. For someone like my self with no network knowledge it...

    GP2X Floating Point And Linking

    (Sorry for slow reply) I'm using the windows version, i've downloaded the one of GPH as well as the one from the gp32x archives. I'm using the latter, but both for me report 4.0.2 Doing a search there is only one gcc.exe in my devkitgp2x dir. ( located C:\devkitGP2X\arm-linux\bin ) Also in...

    Hi, so how is everyone doing with thier code? Here is a little update on mine. Been slowed down a bit as I was ill the past couple weeks and been busy at work. ( GPU == 940 cpu ) Most of the work has been on my GPU code..... Lost texturing as i'm coding my own tri rendering, dumping the code I...

    GP2X Floating Point And Linking

    Are you sure about the gcc version? I've got the sdk from the archives and "gcc --version" reports 4.0.2 When GPH release thier sdk I grabbed it to see if its got a higher gcc version and that also reported 4.0.2 (assuming I checked it correctly ;) )

    GP2X Cycle Latency

    Just tried it, worked a treat. I'm now breaking the protection unit. I'm making all the upper 32 megs cached with a protection hole over that 'landmine' at 16meg so I'll know if I tread on it. So may be a while till its running again. As my raster code is 'very' basic its just one instruction...

    GP2X Cycle Latency

    Thats very intresting about the branch, may have to ask for that book for my birthday. I'm thinking of unrolling my scan line renderer inner loop into a long line of mov's to memory. Then add a value to the PC so that it starts at the correct place and that the last instruction will wright the...

    Mini Stdc++ Lib?

    I seemed to have got hung up on trying to remove the need to link to the standard c++ runtime lib. I almost got my link errors down to zero then I hit the IO init code. Right can of worms. Why am I doing this? At the mo my exec's are over half a meg (release) and 1.2 megs (debug) yet hardly any...

    GP2X What Is The Fastest Way To Develop And Test Apps?

    Just my pennies worth. I dev in 2005 like your self, I have a bat file on the post build events. It copys over the files needed, bin file for 940 and the exe and any data thats changed in the data dir. I've had to put some if's in the batch file to stop it running if the build failed. This is...

    GP2X Just Started Coding

    Yer, after I typed that I thought it sounded a bit 'anti' SDL. Its prob better to use SDL if your a beginner, its just that coding it your self on the 940 is so much fun! :)
