How can I test this using the latest darwinbuild 0.5? I can build from a G3 running OS X 10.3 and try to run on an Athlon XP running OpenDarwin 7.2.1. Also, how do I perform a 'make clean' once a package has been built? Michael

[darwinbuild] Building GCC

Hi, I am trying to build gcc for 8A428 (also tried for 8C46) and getting this error. ERROR: could not find root: SystemStubs I have check the roots directory and found it here http://darwinsource.opendarwin.org/Roots/SystemStubs-5.root.tar.gz, however, darwinbuild is looking for it in the 8A428 sub-directory. It is also not using the version number (5). Is this a mistake? Michael

[darwinbuild] First use of darwinbuild
by John Cebasek 02 Aug '05

Hi All: I am attempting to build Kerberos via darwinbuild (which looks to be a really neat tool). I followed the installation/initialization instructions as per the readme file in the distribution (pretty much following them word for word), and then I tried to actually build Kerberos with this command /usr/local/bin/darwinbuild Kerberos 62. It downloaded quite a few files and then when it actually tried to do the make, it couldn't find make. The error is: private/var/tmp/Kerberos/build-Kerberos-62-2.sh line 96: make command not found. (It also couldn't find date, hostname, tail and cut). Obviously I've got a simple configuration problem. Can you point me to the error of my ways? I'm using Mac OS X 10.4.2 and xCode 2.0 Thanks in advance for your time John Cebasek johnc(a)cryptocard.com

[darwinbuild] RELEASE: Darwin Build Scripts 0.6.1
by Kevin Van Vechten 29 Jul '05

29 Jul '05

The Darwin Build Scripts 0.6.1 release is available[1]. The full list of changes is available on the web[2]. This release addresses the issues preventing Darwin Build 0.6 from downloading pre-built roots from OpenDarwin on Panther systems. Additionally, downloads are now stored in a global cache directory instead of inside each build directory. (Cache directory defaults to $PREFIX/share/darwinbuild/caches/). Furthermore, darwinbuild can now resume interrupted downloads of roots.

[darwinbuild] Building root/header packages
by Michael Franz 29 Jul '05

29 Jul '05

Using darwinbuild, how do I create a root package? When I build I get a directory that I think I think is root. And it might be that simple, but where are the headers if there are header packages a project? - O.K. might be as clear as it could be, but I am not near my system to actually look. What I want to do is build the bsm-2.11 root package, which seems to depend on bsm-2.11 . Is it valid to build this in a non-chroot environment to create the root package? Can I just fake the bsm-2.11 requirement by renaming bsm-2.10 to bsm-2.11? TIA Michael

[darwinbuild] RELEASE: Darwin Build Scripts 0.6
by Kevin Van Vechten 28 Jul '05

28 Jul '05

The Darwin Build Scripts 0.6 release is available[1]. Major improvements include: * darwinbuild installs into /usr/local/bin (or any other PREFIX). * A completely re-written darwinxref tool with plugin support * Build directory hierarchy is now created with `darwinbuild -init 8A428` * Automatically fetches property lists for builds from OpenDarwin servers -- Currently 8C46, 8B15, 8A428, and 7W98 are supported * All builds are performed in a chroot by default (use -nochroot to override). * New `darwinbuild -depsbuild=8A428` argument helps bootstrap new builds * darwintrace logging now resolves volfs (/.vol) paths to POSIX paths * Automatically unmount devfs and volfs from the BuildRoot at exit * Added support for manifests / uuids of roots that are created with DarwinBuild The full list of changes is available on the web[2]. See the read me [3] for more information about the Darwin Build Scripts.

[darwinbuild] No luck building
by darwinbuild＠spam.turbolink.net 27 Jul '05

Ok, so I find a bug in the automounter where it ignores the readahead value set. I figured I'd download the source and simply fix the problem myself. I downloaded the tar.gz file and tried to build it with no success, it's missing header files it needs. In searching for the headers I came across darwinbuild, which seems like exactly what I need: I specify the package, it resolves the dependencies and builds it. Perfect. So I download 0.6 and follow all the instructions exactly. I do "darwinbuild -init 8B15" which works, then a "darwinbuild automount", which fails to locate files.root.tar.gz. Ok, so I make a new directory and try "darwinbuild -init 8A428" which again works, and then "darwinbuild automount". This runs for a long time, downloading dependencies I suppose, then tries to build the target. This fails with the same header files missing (URLMount.h, URLMountPrivate.h) it did originally. Where exactly are these header files supposed to come from? Am I incorrect in assuming that darwinbuild will find and install headers that are required for building? Thanks for any info... - Mike

[darwinbuild] some darwintrace ideas
by Shantonu Sen 13 Jul '05

13 Jul '05

darwinbuild currently uses DYLD_INSERT_LIBRARIES/ DYLD_FORCE_FLAT_NAMESPACE with the "darwintrace.dylib" to log open(2) and execve(2) system calls, for use in dependency analysis. This is great for determining *what* is used during a project build, but not "how" or "why" or "when" Some experimental ideas I'm planning on taking a look at: 1) Full logging of execve(2) arguments 2) shell-escaping the execve(2) arguments so you can copy-paste compiler invocations and such. 3) build a shell script to replay a build, to the extent that this is possible with shell commands. During a build, there is some computation/processing that would not be captured here. 4) synthesize shell commands for some system calls, like mkdir(2) 5) translating volfs paths to normal paths, for better logging of Carbon File Manager clients. 6) tracking system calls to a pid and process name, so you can filter on what a particular process does/did. 7) refactoring compiler invocations, etc., to take common sets of arguments and store them in a shell variable. 8) Some more semantic interpretation of files and paths based on extension, magic, etc. The overall goal is to attack the Darwin self-hosting issue from the tools end, instead of emulating Xcode in a top-down approach. Accomplishing these sets of tasks would get you either some straightforward shell scripts, or possibly makefiles. There should also be intelligent diffing of the end results so you can see what changed between software updates (like a new file was added, and this is immediately obvious). Some of these steps can be done independently and non-sequentially. If you're interested in some of these issues, and want to coordinate, let me know. Shantonu

[darwinbuild] Moved .xref.db into .build
by Kevin Van Vechten 13 Jul '05

13 Jul '05

For those of you working off top-of-tree darwinbuild, I've just moved the xref.db inside the .build directory. Sorry for the seemingly gratuitous change, you should update any of you current darwinbuild working directories with: $ mv .xref.db .build/xref.db If anyone has any other suggestions regarding the .build directory, please say so now, since I'd like to make its format mostly finalized before the 0.6 release. Thanks! - Kevin
