git clone https://github.com/darkmistress5/dm5-core.git
cd dm5-core
./configure --prefix=/opt/dm5 --enable-plugins=all
make -j$(nproc)
sudo make install
Linux post-install tip: Add your user to the dm5 group to avoid sudo for every command: darkmistress5 install
sudo usermod -aG dm5 $USER
newgrp dm5
Approximately 70% of DM5 deployments use this method. Some users need custom compile flags
