Linux Mint 18.3 RT Kernel

Install Linux Mint 18.3 and build and install the RT-PREEMPT kernel for LinuxCNC Uspace.

Download Linux Mint 19.1 and burn to a DVD. I used Linux Mint 18.3 Mate (64-bit)

After installing open a terminal and update then download the RT kernel.

sudo apt-get update
sudo apt-get install -y build-essential bin86 kernel-package libssl-dev
sudo apt-get install -y libqt4-dev libncurses5-dev pkg-config
mkdir rtlinux
cd rtlinux
wget https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/linux-4.19.1.tar.xz
wget https://mirrors.edge.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patch-4.19.1-rt3.patch.gz

Now extract and patch the kernel.

tar -xpf linux-4.19.1.tar.xz
gunzip patch-4.19.1-rt3.patch.gz
cp patch-4.19.1-rt3.patch linux-4.19.1
cd linux-4.19.1
cat patch-4.19.1-rt3.patch | patch -p1
make xconfig

Use ctrl f and search for preempt. Select Fully Preemptible Kernel(RT) Save and close

Now build the kernel.

make
sudo make modules_install
sudo make install

If you get the following:

Warning: No support for locale: en_US.utf8

Then do the following.

sudo dpkg-reconfigure locales
sudo update-locale LANG=en_US.UTF-8

Finally add the grub customizer.

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Next Install LinuxCNC Uspace Linux Mint 18 LinuxCNC
