1. These tools (gmp, mpfr, libmpc, and ncurses) are needed for GCC and GDB installation. On rpm systems such as CentOS, you can run this command as root

yum install gmp-devel mpfr-devel libmpc-devel ncurses-devel

2. On dpkg systems such as Ubuntu, you can run this command as root

apt-get install libgmp-dev libmpfr-dev libmpc-dev libncurses-dev

3. Run the following two commands for the installation of tools and kernel

cd {path-to-your-oslight}; ./install-tools.sh

cd {path-to-your-oslight}; ./install-os161.sh

3. After the installation of tools and kernel, create a sample sys161.conf configration file

cd ${HOME}/os161/root/

cp {path-to-your-sys161-2.0.8}/sys161.conf.sample sys161.conf

4. You may look into sys161.conf for possible modification. The default is fine for now.

5. Create two disk files of 5MB each

disk161 create LHD0.img 5M

disk161 create LHD1.img 5M

6. start this command from one shell

cd ${HOME}/os161/root/; sys161 -w kernel

7. Run os161-gdb from another shell

cd ${HOME}/os161/root/; os161-gdb kernel

8. Type the following command to attach to the kernel

target remote unix:.sockets/gdb
