OSLIB - Exception - Syscall - FW 4.xx. Any working Samples?

[Mr305]

I have made a hard decision to move to Oslib but NOT A SINGLE sample works.

Any one got a simplistic working source that simply blits and image?


I'm using MinPSPW with OSlib devpack.

[MiKeY188]

I have the same problem, It compiles fine sometimes. But it never displays once i click on it.

[brethren]

must be your setup...i've just compiled revision 2418 pspdev, installed oslib headers and libs and compiled the SimpleSample that comes with oslib210, it runs fine on my slim using 401m33-2

here is the sample I have that compiles ok for 4.01 CFW

Can you attach your binaries too? (the compiled eboot)

And what's the 0x200 Module attribute? Never seen it before

[brethren]

that example that xart posted comes with oslib210, its called SimpleSample. Your gonna need to download it yourself for the resources

edit you need to replace your libmikmod with the one that comes with the oslib archive

Got it.

I was using the old sample one that comes with oslib 1.0.0.


THank you all!

What's 0x200; It's not user mode and still it works in 3.xx kernel

[roe-ur-boat]

0x200 is the flag needed to use psp-packer. I don't know what mode it is though, it was asked on lan.st but I don't remember it getting answered.
