我想在 Android NDK 项目中使用 GLM ( glm.g-truc.net ) 仅标头 C++ 库，但出现编译错误。在 中Android.mk，我添加了标题搜索路径

LOCAL_CFLAGS += -I/Users/Johannes/Development/glm_include/

我还尝试使用 STLport 和 GNU-STL 进行编译，方法是Application.mk按照 CPLUSPLUS-SUPPORT 文档中的描述设置以下内容：

APP_STL := stlport_static

或者

APP_STL := gnustl_static

分别。没有什么帮助；这些是我在包含<glm/glm.h>和使用glm::ivec2. ndk-build输出：

After a bit of header hopping, I figured out how to fix this with the GNU libstdc++ runtime.

Try defining _GLIBCXX_USE_C99_MATH to 1 before including <glm.hpp>, like this:

#define _GLIBCXX_USE_C99_MATH 1
#include <glm/glm.hpp>

<glm.hpp> includes <cmath>, which in turn includes <math.h>. The _GLIBCXX_USE_C99_MATH macro forces <cmath> to #undef some macros from <math.h> which would otherwise hide some glm functions like isnan(), isinf(), etc.

Somehow I've managed to compile it. Specifying the following options in the Application.mk did the trick:

APP_OPTIM := release
APP_STL := stlport_static
LOCAL_ARM_MODE := thumb
APP_ABI := armeabi armeabi-v7a

And, I think with the STLport, you can't use RTTI or Exceptions, so don't enable -frtti or -fexceptions in the Android.mk

尝试构建一个像这样的小型示例测试应用程序：

#include <glm/glm.h>
int main(int argc, char* argv[])
{
    return 0;
}

那样有用吗？

If it does, then I'm going to bet that in your app, you have your glm.h include after some #define that has a symbol collision with a symbol that is used in glm. Your #define is probably making use of the sizeof keyword and that is being substituted in the glm lines that have errors.

A possible solution would be to move the glm.h include above any other #includes and/or #defines, if you make it the first thing in the file you may bypass the problem.

A better solution would be to try to avoid #defines and use inline functions whenever possible.

I hope this helps.

I'm running into the same issue when I try to compile glm against gnustl_static, but I don't have any issues when I try to compile with stlport_static. My only suggestion would be to try declaring an stlport dependency using LOCAL_STATIC_LIBRARIES in your shared library module.

Also, have you tried using stlport_shared? stlport has both shared and static libraries, whereas gnustl only has a static version (but supports exceptions/RTTI).
