Actually, I found that my real problem was that I didn't call TTF_Init(). My testing showed that the permissions on the ttf file really doesn't matter.


			Next, I created a font.c file that where I put all of the font code. I created a "drawString(char *)" method that returns a SDL_Surface with the text passed in as a parameter. The prototype for that method is put into the globals.h file, so that the method can be called from my other files.

			If you get a blank black window, then check the permissions on your ttf file:
			$ ls -la *.ttf
			----------+ 1 GaTechGrad None 766656 Oct 9 2006 arial.ttf

			If you don't have read permission, then chmod the file

			chmod u+r arial.ttf
