[tolishot]

hi!i have a problem with my csppc !when i call warp3d apps then shows a message :
powerpc data access exception
task name 'ramlib_ppc'
task address:087ed3b0
task id:105


that message shows!i have install fresh setup about 3-4 times!
my software is:
os3.9
bb1
bb2

Hi!

there's a warpOS library for OS4... and MorphOS also runs Warp3D apps :-)

Anyway, if you insist on using OS3+WarpOS check out in WarpOS preferences that the gfx card base memory is correctly set up. There are also some flags that may affect 3D apps like "terminator" and othes but it's been a long time since I used WarpOS... I advice you installing both MorphOS and OS4 to be able to run everything :-D

Thank You for that! I think with that bit of info I'm going to wipe the 3.9 partition from my 1200 and stick with just 4.0 and MOS. I have enough other machines that I can run 3.9 on that don't have a PPC in them.

It's some age old bug in Warp3D libraries someone never bothered to fix. Basically the library initialization overflows the stack.

a bug? and what triggers it, is it known? Never had this on my 2 csppc A4000's...

[tolishot]

when i buy the csppc card the germany seller mail me the libs and driver for installation csppc.after installation the csppc works great!!both demos 3d and games like wipeout quake heretic and others.the same problem i have also and my amiga 1200ppc.in last week when i install some libs ppc and 3d works!but i dont change the setting in prefs/workbench graphics memory or other memory option.default option is graphics memory and when i try to change it to other memory show a message env/sys cannot be delete !!(a1200ppc message).

help me to correct this problem with exceptions!!if i correct
 this in my a4000 then i try to correct also and my a1200!!
thanks!!! :-?

It's a bug. The Warp3D library init overflows the limited ramlib stack (just 2KB). It depends on the order of the library opening: If you manually open one of the sublibraries first it will hide the bug. Basically if the library init calls OpenLibrary any other diskbased libraries it will cause ramlib to recurse, eating away some of the stack area. If some of the the sublibraries are preloaded to memory the OpenLibrary will return immediately (rather than invoking ramlib again) and not cause further ramlib recursion.

Also, the crash might not happen unpatched system, or if you're just lucky and there's no critial data before the ramlib stack.

The same bug plagued multiple libraries from the same authors. The probram and the solution were brought to their attention years ago, nothing happened.

I told you already. See the earlier post.

[tolishot]

thanks for reply!i want to tell me the steps of this procedure to fix the problem!what to do? :-?

he works this patch in this situation???

[tolishot]

warp3d and warpos works toghether??

@Jeff

Hi! I wouldn't delete your OS3.9 partition! There's software that won't run on OS4/MOS like Demos or old apps. But I keep it with low priority and always boot from OS4 or MOS.

You won't save much space deleting your OS3.9 partition and if your PPC chip dies you will suffer even more because you'll have to reinstall everything again.

@tolishot

follow Piru's advice ;-)

And yes, Warp3D and WarpOS work together.

thanks for advise!i try to run the stuckaid and i tell you what happens! :idea:
