[SDL] Problem compiling code with SDL_ttf

[Alejandro Santos]

Ryan: Looks like you are not linking your program with the SDL_ttf library.
Try adding the parameter -lSDL_ttf to the compiler, after the -lSDL
parameter. Something like this may work:

gcc
fontbuilder.c -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lSDL_ttf -I/us
r/include/SDL -D_REENTRANT

Alejandro.
