Building from source
This section assumes you have the necessary dependencies installed. If not,
check the Installation Guide for a list of dependencies (at least
for Ubuntu) and a more complete guide for compiling from source.
We use nice to set the building process to a lower priority, so it doesn’t
hog memory and CPU resources. We also set -j to the number of cores in your
system to speed up the build process. Note that setting -j without nice can
lead to the system running out of memory/hanging.
git clone https://github.com/leil-io/saunafs.git
cd saunafs
mkdir build
cd build
cmake ..
nice -n 16 make -j$(nproc)
