Make error: DSO missing from command line

Question

I am attempting to install rejoystick, and when I run make, I get this:

What can I do to fix this? (I'm guessing the error is error adding symbols: DSO missing from command line)

Solution

The build is missing -lX11; to work around that, run

./configure LIBS=-lX11 && make
