Hello again
I now have another problem xP with my C++ and SDL.
Im now learning to use the ttf library and Ive linked all the libraries together, and theirs no issues with the compiler trying to find the functions or anything, but when I try to load a font, the ttf_openfont command cant find "lazy.ttf" and returns null, so I end up with the message that the program returned 4, meaning the font failed to load.

Any help as to why the program cant find the font? Posted Image

Thanks!

Heres the source for it:

The ttf file needs to be where the executable can find it. Is it in the same directory as the exe?

The SDL_ttf.dll and libfreetype-6.dll are in the same directory as the .exe., if those are the ones you're talking about.
There is another zlib1.dll that came with ttf but Im using the one that came with SDL_image, if that matters.
Thanks for the reply :) I love your tutorial so far!

do you have the font file in the save directory as the project file? by font file i mean the actual lazy.ttf file, not the dll's. if the error is due to the program being unable to load the font file it means the compiler cant find the lazy.ttf file. just make sure the lazy.ttf file is in the same directory as your compiler's project file if you are running the program through the compiler. if you run it using the .exe file put the lazy.ttf file in the same directory as the .exe.
