    Default I need help using CL_Font with a System font on the Mac

    I am trying to use a System font on the Mac with CL_Font, but I'm failing and I cannot find any sample code in the Examples.

    I am trying this:

    CL_Font fonta("/Library/Fonts/Apple Symbols.ttf", 12);
    printf("Just created fonta\n");
    printf("fonta is valid\n");
    printf("fonta is NOT valid\n");

    This results in the output:

    Just created fonta
    fonta is NOT valid

    Executable “LearningClanLib” has exited due to signal 10 (SIGBUS).

    Any working sample code would be much appreciated!

    I'm not sure (at least from what I've read in the tutorial) that this is what you're supposed to be doing (ie. I doubt you can load ttf directly, but you can use pregenerated bitmap fonts, although that means you'll lose some of the functionality, like good kerning etc). See .

    Anyway, you've asked for a snippet, this is what I use (you need to create your own font.png, or use some of the font's supplied with the examples. Beware, there has to be a completely transparent vertical line between letter/glyphs. Hope this helps
    CL_SpriteDescription glyphs_desc;
    CL_Sprite font_glyphs(glyphs_desc);
    font = CL_Font(font_glyphs, "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789:;_-.,*~!@#$%^&*()[]<>?");

    Default Using a system font versus creating my own font

    Thank you for your reply, Caesar.

    As the documentation you referred to says: "ClanLib makes it possible to create your own font in an image file OR [emphasis added] use existing system fonts." I want an example of using an existing system font, not of creating my own font. I haven't found any examples of this yet. Does everyone create their own font rather than use a system font?
