我正在按照vulkan教程的程序来理解vulkan,我现在正在创建交换链。在此之前,我还创建了示例和调试/验证层,但当我试图创建交换链时,应用程序崩溃。
void createSwapChain() {
VkSurfaceFormatKHR surfaceFormat;
surfaceFormat.format=VK_FORMAT_B8G8R8A8_SRGB;
surfaceFormat.colorSpace=VK_COLOR_SPACE_SRGB_NONLINEAR_KHR;
VkPresentModeKHR presentMode=VK_PRESENT_MODE_FIFO_KHR;
int width,height;
glfwGetFramebufferSize(window, &width, &height);
VkExtent2D extent ={width,height};
uint32_t imageCount=2;//minimum cap +1
VkSurfaceCapabilitiesKHR capabilities;
vkGetPhysicalDeviceSurfaceCapabilitiesKHR(physicalDevice, surface, &capabilities);
VkSwapchainCreateInfoKHR createInfo={0};
createInfo.sType = VK_STRUCTURE_TYPE_SWAPCHAIN_CREATE_INFO_KHR;
createInfo.surface = surface;
createInfo.minImageCount = imageCount;
createInfo.imageFormat = surfaceFormat.format;
createInfo.imageColorSpace = surfaceFormat.colorSpace;
createInfo.imageExtent = extent;
createInfo.imageArrayLayers = 1;
createInfo.imageUsage = VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT;
createInfo.imageSharingMode = VK_SHARING_MODE_EXCLUSIVE;
// createInfo.queueFamilyIndexCount = 1;
// createInfo.pQueueFamilyIndices = NULL;
createInfo.preTransform = capabilities.currentTransform/*VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR*/;//swapChainSupport.capabilities.currentTransform
createInfo.compositeAlpha = VK_COMPOSITE_ALPHA_OPAQUE_BIT_KHR;
createInfo.presentMode = presentMode;
createInfo.clipped = VK_TRUE;// means obscured images have unimportant color!!
createInfo.oldSwapchain = VK_NULL_HANDLE;
if (vkCreateSwapchainKHR(device, &createInfo, NULL, &swapChain) != VK_SUCCESS)
printf("failed to create swap chain!");
}
有什么想法吗?主机是Eclipse,在Windows 10 64位上安装了MinGW-64 -lglfw 3和-lvulkan-1。

几件事:
1.问题描述中没有足够的信息让其他人找到问题所在。例如,我们无法说明
surface
是如何创建的,也无法说明Vulkan设备是如何创建的。最好在某处发布一个完整的可复制示例并指出它。1.当搜索"vulkan交换链异常"如this one和this one时,有很多匹配项,那里的一些东西可能会提供线索。
1.根据上面提供的信息和链接,我最好的猜测是你在创建设备时没有启用交换链扩展。也许你可以检查一下?
1.验证层应该很有用,您可以在here中找到更多信息,您可以尝试创建一个
vk_layer_settings.txt
文件,并使用它将消息严重性设置为"info",以便您可以验证该层是否处于活动状态。(它将在此级别打印某种启动消息)您的IDE可能会吞掉来自验证层的文本输出,这样做的目的是验证您是否可以看到任何验证输出。在同一个设置文件中提供一个日志文件名,将验证输出发送到该文件,而不是弄清楚IDE正在做什么,这可能会更容易。您还可以使用vkconfig
tool将这些类型的设置应用到验证层。
