Question

当尝试使用Android NDK使用Boost c ++库编译程序时，我收到以下类型的错误：

In file included from /home/afeder/android/0ad/jni/lib/boost/boost/assert.hpp:50,
                 from /home/afeder/android/0ad/jni/lib/boost/boost/random/linear_congruential.hpp:21,

显然，Boost提供的一组“断言”函数与NDK本身提供的函数之间存在某种冲突，但我该如何解决呢？

感谢。

头文件有#define宏，它封装了整个头文件内容。在您的来源中，您可以更喜欢取消定义不需要的标题。

示例，如果Boost头文件具有#define BOOST_ASSERT_HPP且NDK具有ANDROID_ASSERT_H，则在源中可以使用#undef BOOST_ASSERT_HPP取消定义与Boost相关的头。

使用Android NDK编译Boost时发生assert.h冲突
