"sudo ranlib /usr/local/lib/libkld.a" worked for me.

Building Darwin 6.5
by Thierry DELHAISE 04 May '03

04 May '03

Like certainly many others, I'm trying to build Darwin 6.5 on my 10.2.5 with December developper tools 2002. I reach the starting point of building xnu since I allready setup all the environment : - I've followed the step describe on OpenDarwin site (right for 10.1.1). I've assumed 10.2.5 could be build like 10.1.1. - finally I face out the problem describe by Michael (kld_builderror) and solve it with the solution provide by Felix. So, I've 'sourced SETUP/setup.csh' - OK make exporthdrs - OK make - KO with creating libsa.o /bin/rm -f vers.c /Volumes/Data/Darwin/xnu/BUILD/obj/RELEASE_PPC/libsa/newvers \ `/bin/cat /Volumes/Data/Darwin/xnu/libsa/conf/version.major /Volumes/Data/Darwin/xnu/libsa/conf/version.minor /Volumes/Data/Darwin/xnu/libsa/conf/version.variant ` /Volumes/Data/Darwin/xnu/libsa/conf/copyright /usr/bin/cc -static -g -nostdinc -nostdlib -no-cpp-precomp -fno-builtin -finline -fno-keep-inline-functions -msoft-float -fsigned-bitfields -Wpointer-arith -fpermissive -arch ppc -Dppc -DPPC -D__PPC__ -D_BIG_ENDIAN=__BIG_ENDIAN__ -O2 -mcpu=750 -mmultiple -fschedule-insns -DAPPLE -DNeXT -DKERNEL_PRIVATE -D__MACHO__=1 -Dvolatile=__volatile -DLIBSA -DKERNEL -DLIBKERN_KERNEL_PRIVATE -Wall -Wno-four-char-constants -fno-common -c vers.c [ updating libsa.o RELEASE ] /usr/bin/ld -static -r -arch ppc -o libsa.o bootstrap.cpo catalogue.cpo c++rem3.o kld_patch.o kmod.cpo mach.o misc.o mkext.o vers_rsrc.o bsearch.o malloc.o sort.o strrchr.o strstr.o setjmp.o vers.o /usr/local/lib/libkld.a /usr/bin/ld: table of contents for archive: /usr/local/lib/libkld.a is out of date; rerun ranlib(1) (can't load from it) make[6]: *** [libsa.o] Error 1 make[5]: *** [build_all] Error 2 make[4]: *** [do_all] Error 2 make[3]: *** [build_all] Error 2 make[2]: *** [build_all] Error 2 make[1]: *** [build_all] Error 2 make: *** [all] Error 2 Since 'libkld.a' is built from cctools/ld, I've rerun 'ranlib' on it (and make a new fresh copy in /usr/local/lib' But nothing works.

Keycode mapping under darwin
by Thierry DELHAISE 04 May '03

04 May '03

Hi all, As a French user of darwin, I would like to "play" with a French Keyboard. Since I come from Unix world (mostly from FreeBSD), I've tried fisrt to search some ioctl to configure the console driver to map the keyboard. I've allready post on this subject in the darwin-x86 list. While waiting some answers, I continue to search in the Kernel Source of darwin. First, I think no ioctl exist on darwin to set key mapping. Second, I think all the job is done inside the keyboard driver (in my case ApplePS2Keyboard) witch is a subset of AppleADBKeyboard. (ADB for AppleDeviceBundle ?). Inside AppleADBKeyboard, I've found that the driver load a default US keymap witch is superset by some info in the Info.plist. am I right ? So to get a French Keyboard, I understood that I have to had a French keymap in the Info.plist of AppleADBKeyboard. Does it is the right way ? Remember, that for now I'm not interest about X11 or Graphics Keyboard mapping. I only want "text console" mapping. THX for your help.

Re: Disk Scheduler

On Friday, May 2, 2003, at 04:29 PM, Joey Echeverria wrote: Does anyone know where the code for the Darwin disk scheduler is located? What do you mean by disk scheduler? I don't believe any such monolithic thing exists in Darwin. I/O requests that go out to disk, depending on their source and entry pathway, usually hit the UBC (universal buffer cache) and can be potentially coalesced with other I/O request (in other words deferred) to make a larger single request out to disk. The file systems involved play a large part in this, it depends on how they originate the I/O request. For the UBC and such you would need to look at the VM sub-system I believe which I think is under xnu/ofsmk (http://www.opensource.apple.com/darwinsource/10.2.5/) The common drivers used to drive disks are generally sub-classes of IOBlockStorageDriver however the meat of the functionality is located in the transport drivers in response to calls via the nubs they publish (sub-classes of IOBlockStorageDevice). IOMedia (and/or sub-classes) sit above the block device/driver and are the main IO abstraction for the higher levels in the system (at least IOKit wise). They can be found in the IOStorageFamily. The following (generated using "ioreg") outlines the IOKit objects involved in the disk IO "stack", some are not much more then glorified registry entries. The IOMediaBSDClient is the shim over into the BSD world. I believe most of the ordering of requests (if any) and/or their deferral happens on the BSD side of things (UBC, VFC, the various FS, etc.).

I had exactly the same problem the last time I did this. I believe that the instructions in "Kernel Programming" are suffering from 'bit rot'. I've filed a bug <rdar://problem/3246832> against "Kernel Programming" so that we remember to update these instructions the next time we revise the document. btw Most people don't know that we track documentation problems via the same system as other bug reports. If you encounter bugs in our documentation, feel free to write up a bug report (URL below). <http://developer.apple.com/bugreporter/> I understand the includes issue. This relates to Apple's ongoing efforts to enforce some degree of binary compatibility within the BSD parts of the kernel. We're trying to make it so that Kernel.framework only contains header files that third party developers can rely on. So certain headers, such as <sys/unistd.h>, which a third party KEXT shouldn't be using, are no longer in Kernel.framework. Of course, the kernel itself shouldn't be subject to this restriction. My solution to the problem is to copy the appropriate headers from "xnu/bsd/sys" into "Kernel.framework/Headers/sys". The seghack error obvious relates to seghack not being in the path used by the build system. I applied the same solution as you (changing the make file to use an absolute path), so I don't know what the full story is.

kld_build Error on Darwin 6.5
by Michael A. Williams 02 May '03

02 May '03

Has anyone seen this compiling Darwin 6.5? iBook with fresh install of OS X 10.2 then the December 2002 developer tools followed by a 10.2.5 update cd. Following the instructions for a kernel build from the November 2002 kernel programming pdf, download and extract from www.opensource.apple.com/darwinsource/10.2.5 bootstrap_cmds, Libstreams, cctools and xnu, everything looks to work as expected until the kld_build in cctools/ld which comes up with an include path error. Searching google and the mailing list archives did not supply any answers.
