Yes. But I wasn't sure from which directory to run it. From your directions, I don't think it's clear if I should be in
Either way, I ran it in both (I assume the Makefile in the parent directory calls the Makefile in the subdirectory) and I still get the same error. Do I need to run it as root (with sudo)?
What is the "uninstalled version"? To me, it seems impossible to run a program that's not installed on your computer. Is this a common term when working with projects under development, in which you might have one version "installed" and other versions in various directories, that aren't "installed"?
