Darling is a runtime environment for OS X applications.
Please note that no GUI applications are supported at the moment.
Darling uses many Git submodules, so a plain clone will not do.
git clone --recurse-submodules https://github.com/darlinghq/darling.git
Updating sources:
git pull
git submodule init
git submodule update
For complete instructions, visit DarlingHQ.org.
cd darling
mkdir -p build/x86-64
cd build/x86-64
cmake ../.. -DCMAKE_TOOLCHAIN_FILE=../../Toolchain-x86_64.cmake
make
make install
# Now we go into src/lkm to build the kernel module
cd ../../src/lkm
make
make install
cd darling
mkdir -p build/i386
cd build/i386
cmake ../.. -DCMAKE_TOOLCHAIN_FILE=../../Toolchain-x86.cmake
make
make install
Loading the kernel module:
modprobe darling-mach
# ATTENTION: The kernel module is likely unstable,
# full of vulnerabilities, etc.
# You SHOULD restrict access to /dev/mach to trusted
# users only and be prepared to the eventuality of
# kernel hangups (and related data loss).
chmod a+rw /dev/mach
Let's start with a Hello world:
$ darling shell echo Hello world
Hello world
Congratulations, you have printed Hello world through Darling's OS X system call emulation and runtime libraries.
You can install .pkg packages with the installer tool available inside shell. It is a somewhat limited cousin of OS X's installer:
$ darling shell
Darling [~]$ installer -pkg mc-4.8.7-0.pkg -target /
If you have previously downloaded the Midnight Commander package from Rudix, you can now run mc to start MC for OS X. For easier installation, install the Rudix Package Manager. Note that not all Rudix packages may work under Darling.
You can uninstall and list packages with the uninstaller command.
DMG images can be attached and deattached from inside darling shell with hdiutil. This is how you can install Xcode along with its toolchain and SDKs (note that Xcode itself doesn't run yet):
Darling [~]$ hdiutil attach Xcode_7.2.dmg
/Volumes/Xcode_7.2
Darling [~]$ cp -r /Volumes/Xcode_7.2/Xcode.app /Applications
Darling [~]$ export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk
Darling [~]$ echo 'void main() { puts("Hello world"); }' > helloworld.c
Darling [~]$ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang helloworld.c -o helloworld
Darling [~]$ ./helloworld
Hello world
Congratulations, you have just compiled and run your own Hello world application with Apple's toolchain.
