I have an Ubuntu 14.10 64 Bit.
I use head from the ClanLib github Repo.

I get the following error by compile clanDisplay:
Code:
Font/font_face_impl.cpp: In member function 'void clan::FontFace_Impl::load_font(const clan::FontDescription&, clan::DataBuffer&)':
Font/font_face_impl.cpp:97:4: error: 'filename' was not declared in this scope
    filename = PathHelp::get_filename(font_file_path, PathHelp::path_type_file);
    ^
Font/font_face_impl.cpp:98:4: error: 'fs' was not declared in this scope
    fs = FileSystem(path);
    ^
What am I doing wrong?
