我想在Android NDK项目中使用仅GLM(glm.g-truc.net) header 的C++库，但是出现编译错误。在Android.mk中，我添加了标题搜索路径
LOCAL_CFLAGS += -I/Users/Johannes/Development/glm_include/
并且我还尝试通过在
Application.mk中设置以下内容(如CPLUSPLUS-SUPPORT文档中所述)来使用STLport和GNU-STL进行编译:APP_STL := stlport_static
或者
APP_STL := gnustl_static
分别。没有任何帮助；这些是我在包含
<glm/glm.h>和使用glm::ivec2时遇到的错误。 ndk-build输出:Compile++ arm : wbar <= QCARBase.cpp

我正在使用Crystax NDK r6(www.crystax.net)
最佳答案
经过一些标题跳跃之后，我想出了如何使用GNU libstdc++运行时解决此问题。
在包含_GLIBCXX_USE_C99_MATH之前，尝试将<glm.hpp>定义为1，如下所示:
#define _GLIBCXX_USE_C99_MATH 1
#include <glm/glm.hpp>
<glm.hpp>包括<cmath>，而<math.h>又包括_GLIBCXX_USE_C99_MATH。 <cmath>宏强制#undef将<math.h>中的一些宏glm变为isnan()，否则它们将隐藏一些isinf()函数，例如ojit_code，ojit_code等。关于c++ - 仅 header 的C++库(GLM)无法与Android-NDK一起编译，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/7435602/
