hmm..., I don't know if it's different for PPC from x86, but I've built many different versions of the kernel fine basically following the 10.1 instructions on an x86 machine. The only thing I had to do not mentioned there was copy /usr/include/mach-o from a Mac OS X 10.2 box. -jwa Martedl, 14 gen 2003, alle 22:18 US/Pacific, Jeff Jenkins ha scritto: Hi, I have seen several posts to this list asking for: 1. what CVS tag to use to get a function kernel that is somewhere close to what Jaguar is based on. 2. how to build this source into to a binary kernel that works.

All UI elements are handled by userland applications (WindowServer, and the various drawing frameworks). So accessing these elements is next to impossible in kernel. Finally, there really are no "system globals" in the sense of OS 9. A lot of things that we're globals are now process specific, and those that are still globals (through shared mem. or something else) are not easily accessible.

mount_msdos and libdisk.a
by George André 08 Jan '03

08 Jan '03

Hi, The msdosfs module in the open source CVS contains the source code to mount_msdos(8). The linking stage of this project requires libdisk.a (-ldisk). Does anyone know where this library is, alternatively which CVS module it is in? I'm using 10.1.5 and the April2002 Dev tools (PB 2 beta). George. _______________________________________________ darwin-kernel mailing list | darwin-kernel(a)lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
