Still having SDL_ttf Problems on Redhat 8.0

I installed SDL_ttf on my Redhat 8.0 system (first I changed to spec
file to get around the /usr/bin/showfont issue, then I installed from
source into /usr). Either way I installed it, I could compile my
programs that needed SDL_ttf, but when I run the program all the fonts
show up as squares. The /usr/bin/showfont program also displays
everything as squares. Is there some other Library that I need
(SDL_ttf, didn’t complain at all when I compiled it)? Is Redhat 8.0
broken somehow?

When I take the exact same source code and compile it on a Redhat 7.x it
works fine.
