Нарушение доступа при вызове vkcreateinstance ()? ⇐ C++

[Anonymous]

Я написал простую программу Vulkan: < /p>

Код: Выделить всё

VkResult GetLayersAndExtensions() {
#ifndef NDEBUG
GraphicsBase::GetInstance().AddInstanceLayer("VK_LAYER_KHRONOS_validation");
GraphicsBase::GetInstance().AddInstanceExtension(VK_EXT_DEBUG_UTILS_EXTENSION_NAME);
#endif
uint32_t instanceExtensionCount = 0;
const char **instanceExtensionNames = nullptr;
instanceExtensionNames = glfwGetRequiredInstanceExtensions(&instanceExtensionCount);
if (!instanceExtensionNames) {
LOGE(TAG_GLFW, "get instance extensions failed");
glfwTerminate();
return VK_ERROR_EXTENSION_NOT_PRESENT;
}
for (uint32_t index = 0; index < instanceExtensionCount; ++index) {
LOGI(TAG_GLFW, "instance extension {}: {}", index, instanceExtensionNames[index]);
GraphicsBase::GetInstance().AddInstanceExtension(instanceExtensionNames[index]);
}
GraphicsBase::GetInstance().AddDeviceExtension(VK_KHR_SWAPCHAIN_EXTENSION_NAME);
return VK_SUCCESS;
}

VkResult CreateInstance() {
VkApplicationInfo applicationInfo = {
.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO,
.apiVersion = _apiVersion
};
VkInstanceCreateInfo createInfo = {
.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO,
.pApplicationInfo = &applicationInfo,
.enabledLayerCount = static_cast(_instanceLayers.size()),
.ppEnabledLayerNames = _instanceLayers.data(),
.enabledExtensionCount = static_cast(_instanceExtensions.size()),
.ppEnabledExtensionNames = _instanceExtensions.data()
};
VkResult result = vkCreateInstance(&createInfo, nullptr, &_instance);
if (result) {
LOGE(TAG_COMMON, "create vulkan instance failed, result is {}", std::to_string(result));
return result;
}
return VK_SUCCESS;
}

... но он сбои, когда я вызываю vkcreateinstance () :

Я пробовал удалить Vulkan, но это не работает.
