android - Vulkan API 示例构建失败

Question

我正在按照以下说明操作:https://developer.android.com/ndk/guides/graphics/getting-started并在编译任何模块时保持gettig以下错误:

Build command failed.

我对此绝对是新手，没有原生 android 开发经验。请帮我解决这个问题，拜托!我的论文非常需要它!

Ubuntu 14.04；安卓工作室 3.1.2；NDK:r17；编译SDK: API 24: Android 7.0 (Nougat); Gradle 3.3

看起来问题出在 android NDK header 中。具体在:

Android/Sdk/ndk-bundle/sources/third_party/shaderc/include/shaderc/shaderc.hpp

它们将 shaderc::CompileOptions::IncluderInterface 声明为虚类，但没有虚析构函数:

  class IncluderInterface {
      public:
      // Handles shaderc_include_resolver_fn callbacks.
      virtual shaderc_include_result* GetInclude(const char* requested_source,
                                           shaderc_include_type type,
                                           const char* requesting_source,
                                           size_t include_depth) = 0;

      // Handles shaderc_include_result_release_fn callbacks.
      virtual void ReleaseInclude(shaderc_include_result* data) = 0;
  };

我通常不会推荐这个，但看起来你别无选择。您可以从 make 文件中删除 -Wdelete-non-virtual-dtor 或 -Werror 以便它不会因该错误而出错？可能不是长期的解决方案...更好的解决方案是找出谁制作了第三方 header :shaderc.hpp 并请他们很好地修复它...

其他选项是在 Java SDK 中使用 OpenGL，或者从废料中编写 Vulkan 部分而不使用示例代码。我最近写了一个使用 Vulkan 的 android 应用程序，并没有遇到这个错误。
