Question

我正在尝试在Xcode中使用imagemagick，我收到此错误：

Undefined symbols for architecture x86_64:

      _main in main.o
  "Magick::Image::Image(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)", referenced from:

  "Magick::Image::~Image()", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64

任何帮助都将不胜感激。
