Vulkan实例创建失败

Question

我有一个vulkan程序在我的笔记本电脑上运行，但在我的台式机上失败了。错误是：

HeatMethod: ../libraries/vulkansdk-linux/1.2.154.0/source/Vulkan-Headers/include/vulkan/vulkan.hpp:13143: typename vk::ResultValueType<vk::UniqueHandle<Type, Dispatch> >::type vk::createResultValue(vk::Result, T&, const char*, const typename vk::UniqueHandleTraits<Type, Dispatch>::deleter&) [with T = vk::Instance; D = vk::DispatchLoaderStatic; typename vk::ResultValueType<vk::UniqueHandle<Type, Dispatch> >::type = vk::ResultValue<vk::UniqueHandle<vk::Instance, vk::DispatchLoaderStatic> >; typename vk::UniqueHandleTraits<Type, Dispatch>::deleter = vk::ObjectDestroy<vk::NoParent, vk::DispatchLoaderStatic>]: Assertion `result == Result::eSuccess' failed.

我使用注释来跟踪问题，并发现它发生在实例创建时：

// Global scope
const std::vector<const char*> VALIDATION_LAYERS = {
    "VK_LAYER_KHRONOS_validation",
};

   // Setup general information about the current application
    vk::ApplicationInfo program_info(
        "Vulkan Engine",
        VK_MAKE_VERSION(1, 0, 0),
        "No Engine",
        VK_MAKE_VERSION(1, 0, 0),
        VK_API_VERSION_1_2);

    if(!CheckAvailableLayers())
        RecordLogError("Validation layers requested, but not available!");

    vector<const char*> required_extensions;
    if(!RequestExtensions(required_extensions))
        RecordLogError("Missing a required extension");
    // Create Vulkan instance to communicate with the loader
    vk::InstanceCreateInfo createInfo(
        {},
        &program_info,
        static_cast<uint32_t>(VALIDATION_LAYERS.size()),
        VALIDATION_LAYERS.data(),
        static_cast<uint32_t>(required_extensions.size()),
        required_extensions.data());
    auto [result, instance] = vk::createInstanceUnique(createInfo);

这个错误本身就是hpp报头中的一个失败断言，所以它有点神秘。我不确定问题出在哪里。

Answer 1

尝试在构建脚本上设置验证层时出现问题：

os.environ['VK_INSTANCE_LAYERS'] = 'VK_LAYER_LUNARG_standard_validation'

删除该行就解决了这个问题。
