First extract the archive to a sensible place:
tar -xzvf lepton-eda-1.9.18.tar.gz && cd lepton-eda-1.9.18
Run the configuration script. You’ll probably want to specify a custom directory to install Lepton EDA to, for example:
./configure --prefix=$HOME/lepton
You can then compile Lepton:
make
And install it (if you used a --prefix outside your
$HOME
directory, you may need to run this as root):
make install
