Quick SDL_ttf question

I have exactly the same problem as
http://www.gamedev.n...osx-104-solved/
which he has solved, but I just don't know what he means by src folder?
At first I thought he might mean the folder where all the source files
are but that didn't work...so close to the answer but oh so far!

If you put font intro directory then use
"./Myfolder/Mynextfolder/Myfontfile.ttf"

find the default directory of your project and from then it should be easy

Right - You need to specify the proper relative path (relative to the directory from which the program was executed), or the absolute path to the font file.

I would try doing the latter first, just to make sure that font loading code works, and then you can try relative paths.

Thank you very much for your attempt to help!
I have tried both downloading a font (Eight One.ttf)
and getting one from the windows fonts folder (arial)
I have both these font files copied into the Release folder, Debug folder
the folder where the project is and also in the folder C:\fonts
It seems like I am trying every possible thing!?!?

TTF_Font* font = TTF_OpenFont("arial", 50); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("Eight One", 50); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("Eight One.ttf", 50); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("C:\\fonts\\Eight One.ttf", 12); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("arial.ttf", 12); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("Eight One.ttf", 12); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("./arial.ttf", 12); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
font = TTF_OpenFont("./Eight One.ttf", 12); //Magic number
if (font == NULL){
std::cerr << "Unable to load font" << std::endl;
}
else{
SDL_Color red; //Move this definition
red.r = 255;
red.g = 0;
red.b = 0;
textSurface_ = TTF_RenderUTF8_Blended(font,text.c_str(),red);
}

Each of these returns NULL. I am sure it is just something silly but
I have initialised SDL_TTF (after I have created the screen)
I am just stuck for ideas??
Its so frustrating when you just cannot move your project
forward even though you know what the problem is!
