我正在为 Android 构建一个 3d 模型查看器应用程序。模型的显示和查看是通过 OpenGL 用 C++ 编写的，我正在使用 Android NDK 将其与 android 应用程序相结合。但是，当我尝试部署应用程序时，会遇到许多处理 OpenGL 代码的错误，例如：
/Users/Preddy/Downloads/9781119975915/SDK/_chapter3-2/Android//jni/../../../common/GLES2/gl2.h:501: error: expected constructor, destructor, or type conversion before 'void'

我显然在这里的设置中遗漏了一些东西。我正在使用 Sequoyah（用于编译和调试本机代码）和 NDK 版本。r5b（因为 Sequoyah 无法识别更高版本）。欢迎任何建议，我开始绝望。
