Please correct if something is not right, using this I am running all the examples successfully!
1.) install rust Nightly (the compiler)
http://www.rust-lang.org/install.html4 or on mac/linux
curl -sSf https://static.rust-lang.org/rustup.sh | sudo sh -s -- --channel=nightly
2.) install gcc (linux sudo apt-get install gcc)
3.) clone crust (install git if you don’t have it sudo apt-get install git on linux)
git clone https://github.com/maidsafe/crust.git
4.) go into the crust folder:
cd crust
5.) install libsodium if you have not yet done so
Unfortunally, there are not libsodium packages for Ubuntu. So, you should download, build and install libsodium as follows:
Download the newer tar archive from Index of /libsodium/releases/ (you can also get the git repository from GitHub - jedisct1/libsodium: A modern, portable, easy to use crypto library.).
Follow the ritual:
tar xzf libsodium-1.0.3.tar.gz
cd libsodium-1.0.3/
./configure
make && make check && sudo make install
Once you have installed you have to reload/rebuild the GNU linkers. A simple sudo ldconfig is enough.
Now run ./configure and it should generate the makefile. (I’m assuming you have at least build-essentials package installed).
6.)cd crust
( to run crust_peer)
cargo run --example crust_peer
