windows: I am in the PD directory where all the main files are. I use
make app

error:
$ make app
makefile:4: ../makefile.subdir: No such file or directory
make: *** No rule to make target '../makefile.subdir'. Stop.

did you do ./autogen.sh and ./configure first? Idk about compiling on Windows but that's what it says in INSTALL.txt

Thank you that corrected my issue
