Deploying DarwinBuild on PureDarwin

This page is about attempting to run DarwinBuild on a PureDarwin system (consequently, making PureDarwin a bit more self-hosted).

Get Darwinbuild

Homebrew

As of 2015, Darwinbuild can be installed using Homebrew, however it fails.

brew install --HEAD homebrew/head-only/darwinbuild
(...)
==> Installing darwinbuild from homebrew/homebrew-head-only
==> Cloning http://svn.macosforge.org/repository/darwinbuild/trunk/

SVN

svn co http://svn.macosforge.org/repository/darwinbuild/trunk darwinbuild

MacPorts

port archive darwinbuild

DarwinBuild

Unfortunately, there is no darwinbuild project in darwinbuild:

darwinbuild darwinbuild
ERROR: project not found: darwinbuild

Somebody needs to fix that (TODO: add darwinbuild)

Compiling Darwinbuild in a PureDarwin chroot

See Deploying MacPorts on PureDarwin for some prerequisites (gcc stuff and some usefull dev tools).

cd /Volumes/PureDarwin
# These dependencies will be needed:
tar xzvf /Volumes/Builds/9G55/Roots/.DownloadCache/libdyld.root.tar.gz                    
tar xzvf /Volumes/Builds/9G55/Roots/.DownloadCache/Libsyscall.root.tar.gz

We will temporary grab an old trick used by darwinbuild previously in order to avoid some project to raise this error: 

/bin/sh: dsymutil: command not found

chroot .
cp /usr/bin/true /usr/bin/dsymutil
LDFLAGS=-L/opt/local/lib make

make install

cd somewhere
darwinbuild -init <build version>
