Full Node on Raspberry Pi 3

So..I am trying to run a full node on my Raspberry Pi 3. For that I followed this guide: http://www.raspberrypifullnode.com/

But I am failing at these statements:

Quote

./autogen.sh
./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib" --disable-wallet
make
sudo make install

When I try to run the "make" command, it fails because it says that there is no make file...hmmm.
Any help?
