Got this error when I run make. Does anyone know how I could solve this?

you need to have the libreadline development libraries installed. We do a pkg-config check for them, but the error case just adds the library linker option in because it wasnt until recently that the readline .pc file was included. I can change that, but the change will just update the error above to fail during configure, indicating that you need the readline-devel package

@nhorman Got it! Thanks!!

I get libreadline is required even if libreadline7 is installed.
