Objective-C/GNUStep workspace in linux via vagrant (for learning purposes).
Use this workspace to learn the basics of Objective-C without having a Mac.
Vagrant + VirtualBox + Git
The first time you start the virtual-machine (vagrant up) it will install all the required packages (it may take some minutes).
git clone https://github.com/josketres/objectivec-linux-vagrant
cd objectivec-linux-vagrant
vagrant up
Ssh into the virtual-machine, compile and run the example /workspace/helloworld.h
vagrant ssh
# once inside the virtual-machine
cd /workspace
# compile the example
make
# run the compiled example
./obj/helloworld
