This is probably my fault, but I don't know how I screwed this up, so any help is appreciated.
I've been doing development of my game on an Ubuntu computer, and I just decided to do an upgrade the other day. During the upgrade, a bunch of packages that were not in use were uninstalled, and I think that's where I messed up. Today, when I go to compile my game, I get this error:
make[3]: *** No rule to make target `/usr/lib/libX11.so', needed by `lib/libsfml-window.so.2.0.0'. Stop.
My first thought was to open synaptic and see if anything jumped out at me, but it's telling me that libx11 and libx11-dev are indeed installed, and that was my only decent guess as to what package I might be missing.
Does anyone know what piece of this puzzle I'm missing?
