To get it up and running, you need to download & extract the latest source code and type make where you extracted the archive.

If you're lucky, what should happen next is something like this:

make -C nfpvrmake[1]: Entering directory `/cygdrive/c/Code/nfpvr/nfpvr'
make -C ../nfpvrlib
make[2]: Entering directory `/cygdrive/c/Code/nfpvr/nfpvrlib'
make[2]: Nothing to be done for `all'.
make[2]: Leaving directory `/cygdrive/c/Code/nfpvr/nfpvrlib'
g++ -cProgramOptions.cpp -Wall -I../nfpvrlib
g++ -c nfpvr.cpp -Wall -I../nfpvrlib
g++ -o nfpvr ProgramOptions.o nfpvr.o -L../nfpvrlib -lnfpvr
make[1]: Leaving directory `/cygdrive/c/Code/nfpvr/nfpvr'

You can now run nfpvr/nfpvr to start the server.
