NOTE: This is still super super early in development. (To see what has been implemented you can read Foundation.h, the uncommented classes are implemented. Although not all are finished)
Foundation lite is a limited subset of Cocoa's Foundation framework, intented for use on Linux (x86_64).
It deliberately only implements only the absolute core components of Foundation with the goal of making it feasible to deploy Objective-C on Linux servers.
Most of the types implemented are simple wrappers around Apple's own CoreFoundation Lite (hence Foundation Lite), meaning that these are no half-assed implementations I whipped up in my spare time, and should have roughly the same performance characteristics as those on MacOS, and will be updated with each release of it.
- clang 3.2+ (Latest recommended): http://clang.llvm.org/
- CFLite: https://github.com/fjolnir/CoreFoundation-Lite-Linux
- libBlocksRuntime: http://compiler-rt.llvm.org/
- ICU4C 4.4+: http://site.icu-project.org/
- libobjc2 http://svn.gna.org/svn/gnustep/libs/libobjc2/
Install the latest version of clang using one of the sources on http://llvm.org/apt
sudo echo "<repo url>" >> /etc/apt/sources.list
wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install clang-3.4
sudo apt-get install libblocksruntime-dev
sudo apt-get install libicu-dev
svn co http://svn.gna.org/svn/gnustep/libs/libobjc2/
mkdir libobjc2/build
pushd libobjc2/build
cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
make
sudo make install
popd
git clone https://github.com/fjolnir/CoreFoundation-Lite-Linux.git cflite
pushd cflite
sudo make -f MakefileLinux install
popd
And then simply execute make in your Foundation-Lite directory to try it out. (There's no make install yet because it is not mature enough to warrant installing)
The easiest way to begin contributing is to help increase the test coverage. The test format is very simple and anyone with Objective-C experience should be able to learn it just by glancing at the files in testcases/
And of course I welcome implementations of any NS* classes that I have not gotten around to yet!
