[darwinbuild] Building Intel xnu with darwinbuild
by Shantonu Sen 21 Aug '06

21 Aug '06

Currently, the build instructions at <http://kernel.macosforge.org/intel-build-instructions.html > require downloading a tarball of kernel build tools, and building the kernel with "make". Instead of doing so, you can use darwinbuild, which will do things like save the symboled version of the kernel, etc.. Instead of: • Download and install the kernel tools, a small set of additional command line tools (from the bootstrap_cmds and cctools projects) required to compile xnu. • Download the xnu-792.10.96 sources. • Extract the sources and build the kernel: You can now do the following. Since all dependencies are built from source except for the BuildRoot loaded from your root filesystem, this avoids the problem of downloading binary roots that may not be compatible with your system. Note that the other instructions on that page, specifically installing Xcode 2.4 and the updated kernel extensions, are still needed. 1) Download and install CVS darwinbuild. darwinbuild 0.7.2 does not have the required functionality 2) Download <http://www.opendarwin.org/~ssen/darwinbuild-xnu-support.tar.gz > and extract it in your build area 3) Initialize your build area: # /usr/local/bin/darwinbuild -init 8K1079.plist 4) Using the tips at <http://forums.macosxhints.com/archive/index.php/t-50441.html >, download required APSL source. If your cookie times out, you may need to re-issue the curl line, and remove malformed tarballs from Sources/ # cookiepath=/tmp/com.apple.daw.apsl.cookie # username=XXX # password=YYY # curl -L "https://daw.apple.com$(curl -sL http://www.opensource.apple.com/darwinsource/tarballs/apsl/ | grep appleConnectForm | awk 'BEGIN { RS = "\"" } ; {print $1}' | grep cgi)?theAccountName=$username&theAccountPW= $password" -c $cookiepath # export CURLARGS="-b $cookiepath" # /usr/local/bin/darwinbuild -source bootstrap_cmds # /usr/local/bin/darwinbuild -source cctools # /usr/local/bin/darwinbuild -source cctools_ofiles # /usr/local/bin/darwinbuild -source kext_tools # /usr/local/bin/darwinbuild -source xnu 5) Load BuildRoot, based on the contents of your root filesystem. Then build required dependencies, in order # /usr/local/share/darwinbuild/createChroot # /usr/local/bin/darwinbuild bootstrap_cmds # /usr/local/bin/darwinbuild -load bootstrap_cmds # /usr/local/bin/darwinbuild -headers xnu # /usr/local/bin/darwinbuild -headers -load xnu # /usr/local/bin/darwinbuild cctools # /usr/local/bin/darwinbuild -load cctools # /usr/local/bin/darwinbuild cctools_ofiles # /usr/local/bin/darwinbuild -load cctools_ofiles # /usr/local/bin/darwinbuild kext_tools # /usr/local/bin/darwinbuild -load kext_tools 6) Build xnu # /usr/local/bin/darwinbuild xnu At this point, you can install the results however you'd like, including the updated drivers that are needed.

[darwinbuild] two issues
by Dale Walsh 21 Aug '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 First, this has probably been asked before but where can I find the plist files for 10.4.6 or 10.4.7. Second, I've built darwinbuild 0.7.2 on an intel iMac and I was trying to build xnu in 8G32 but I get the following: Mounting volfs ... /usr/local/bin/darwinbuild: line 791: 2430 Illegal instruction chroot "$BuildRoot" /sbin/mount_volfs "/.vol" I've created the build on an external FW drive and when I plug it in to a ppc Mac it works without issues so I'm not entirely sure of where the problem is. I don't need to build anything below 10.4.6 (Darwin 8.6) so a working plist would be helpful. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (Darwin) iD8DBQFE4oU0iD9DTPch4RQRAk89AJ9zs4th1QHxWIBOj7IGfXr5rV7IjQCfS+4d WMU7KCruW3XyUj5agZv4n3k= =1msq -----END PGP SIGNATURE-----
