我正在用vulkan（暂时）制作一个简单的渲染器，此刻我正在使其变得非常简单。我在vkCreateGraphicsPipelines（）处遇到异常，可能是什么问题，我将如何解决。
我尝试查找尚未初始化的任何内容，但到目前为止没有任何内容。我已经检查了调用堆栈，但一无所获，因为调用管道的create函数时会引发异常。我也在google上搜索，但没有找到任何帮助。我关注的是vulkan教程网站，只是将其抽象为不同的类，多次检查了该教程。一切正常，直到我进入vkCreateGraphicsPipelines函数。
VkPipelineShaderStageCreateInfo shaderStages[] = { p_Model->shader.vertShaderStageInfo, p_Model->shader.fragShaderStageInfo };
VkPipelineVertexInputStateCreateInfo vertexInputInfo = {};
vertexInputInfo.sType = VK_STRUCTURE_TYPE_PIPELINE_VERTEX_INPUT_STATE_CREATE_INFO;
vertexInputInfo.vertexBindingDescriptionCount = 1;
vertexInputInfo.vertexAttributeDescriptionCount = static_cast<uint32_t>(p_Model->mesh.vao.getAttributeDescriptions().size());
vertexInputInfo.pVertexBindingDescriptions = &p_Model->mesh.vao.getBindingDescription();
vertexInputInfo.pVertexAttributeDescriptions = p_Model->mesh.vao.getAttributeDescriptions().data();
//Set info for graphics pipeline creation
VkPipelineInputAssemblyStateCreateInfo inputAssembly = getInputAssemblyInfo();
VkViewport viewport = getViewport();
VkRect2D scissor = getScissor();
VkPipelineViewportStateCreateInfo viewportState = getViewportStateInfo(viewport, scissor);
VkPipelineRasterizationStateCreateInfo rasterizer = getRasterizerInfo();
VkPipelineMultisampleStateCreateInfo multiSampling = getMultiSamplingInfo();
VkPipelineColorBlendAttachmentState colorBlendAttachment = getColorBlendAttachmentState();
VkPipelineColorBlendStateCreateInfo colorBlending = getColorBlendStateInfo(colorBlendAttachment);
VkPipelineDynamicStateCreateInfo dynamicState = getDynamicStateInfo();
VkPipelineLayoutCreateInfo pipelineLayoutInfo = getPipelineLayoutInfo();
//Filling pipeline info
VkGraphicsPipelineCreateInfo pipelineInfo = {};
pipelineInfo.sType = VK_STRUCTURE_TYPE_GRAPHICS_PIPELINE_CREATE_INFO;
pipelineInfo.stageCount = 2;
pipelineInfo.pStages = shaderStages;
pipelineInfo.pVertexInputState = &vertexInputInfo;
pipelineInfo.pInputAssemblyState = &inputAssembly;

pipelineInfo.pMultisampleState = &multiSampling;
pipelineInfo.pDepthStencilState = nullptr;
pipelineInfo.pColorBlendState = &colorBlending;
pipelineInfo.pDynamicState = &dynamicState;
pipelineInfo.layout = pipelineLayout;
pipelineInfo.renderPass = renderPass;
pipelineInfo.subpass = 0;
pipelineInfo.basePipelineHandle = VK_NULL_HANDLE;
pipelineInfo.basePipelineIndex = -1;
if (vkCreatePipelineLayout(m_Context->device, &pipelineLayoutInfo, nullptr, &pipelineLayout) != VK_SUCCESS)
Utils::Logger::logMSG("Failed to create pipeline layout\n", "Rendering", Utils::Category::Error);

着色器代码

throw std::runtime_error("failed to open file");
size_t fileSize = (size_t)file.tellg();
std::vector<char> buffer(fileSize);
file.seekg(0);
file.read(buffer.data(), fileSize);
file.close();
return buffer;
}
void VulkanShader::setShader(std::string p_VertexShader, std::string p_FragmentShader)
{
auto vertShaderCode = readFile(p_VertexShader);
auto fragShaderCode = readFile(p_FragmentShader);
vertShaderModule = createShaderModule(vertShaderCode);
fragShaderModule = createShaderModule(fragShaderCode);
vertShaderStageInfo = {};
vertShaderStageInfo.sType = VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_CREATE_INFO;
vertShaderStageInfo.stage = VK_SHADER_STAGE_VERTEX_BIT;
vertShaderStageInfo.module = vertShaderModule;
vertShaderStageInfo.pName = "main";
fragShaderStageInfo = {};
fragShaderStageInfo.sType = VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_CREATE_INFO;
fragShaderStageInfo.stage = VK_SHADER_STAGE_FRAGMENT_BIT;
fragShaderStageInfo.module = fragShaderModule;
fragShaderStageInfo.pName = "main";
}
VkShaderModule VulkanShader::createShaderModule(const std::vector<char>& p_Code)
{
VkShaderModuleCreateInfo createInfo = {};
createInfo.sType = VK_STRUCTURE_TYPE_SHADER_MODULE_CREATE_INFO;
createInfo.codeSize = p_Code.size();
createInfo.pCode = reinterpret_cast<const uint32_t*>(p_Code.data());
VkShaderModule shaderModule;
if (vkCreateShaderModule(vkContextSingleton::getInstance().device, &createInfo, nullptr, &shaderModule) != VK_SUCCESS)
Utils::Logger::logMSG("Failed to create shader module\n", "Shader", Utils::Category::Error);
return shaderModule;
}
这是错误消息

控制台的输出（不是真正的格式，我只是想让事情先生效）

该评论使我意识到我的验证层不起作用。我myslef认为他们做到了。忘记在实例创建中启用验证层。
