Question

我在C ++程序中使用Magick ++，我看到以下警告信息：

In file included from /Users/jwoods/Projects/glidar/src/main.cpp:40:

#  define magick_alloc_sizes(x,y)  /* nothing */

2 warnings generated.

我将Magick ++包含在我认为是头文件的正常方式中，

#ifndef MY_HEADER_H
# define MY_HEADER_H
# include <Magick++.h>
#endif

所以我认为问题出在Magick ++中，而不是我的程序。

我在谷歌搜索了一下这个警告，但没有找到任何明显的解决方法来摆脱它。

如何摆脱magick_alloc_size宏重新定义的警告
