I met a segmentation fault #228

Open fake-rookie opened 3 years ago

fake-rookie commented 3 years ago

Following is code:

#include <cstdlib>
#include <iostream>
#include <stdexcept>
#include <GLFW/glfw3.h>
#include <vulkan/vulkan.h>

#define GLFW_INCLUDE_VULKAN

const uint32_t WIDTH  = 800;
const uint32_t HEIGHT = 600;

class HTA {
public:
    void run();
private:
    GLFWwindow *window;
    VkInstance instance;

    void initWindow();
    void initVulkan();
    void mainLoop();
    void cleanUp();
    void createInstance();
};

void HTA::run()
{
    initWindow();
    initVulkan();
    mainLoop();
    cleanUp();
}

void HTA::initWindow()
{
    glfwInit();

    glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
    glfwWindowHint(GLFW_RESIZABLE, GLFW_FALSE);

    window = glfwCreateWindow(WIDTH, HEIGHT, "Vulkan Triangle", nullptr, nullptr);
}

void HTA::initVulkan()
{
    createInstance();
}

void HTA::mainLoop()
{
    while (!glfwWindowShouldClose(window)) {
        glfwPollEvents();
    }
}

void HTA::cleanUp()
{
    vkDestroyInstance(instance, nullptr);
    glfwDestroyWindow(window);
    glfwTerminate();
}

void HTA::createInstance()

{
    VkApplicationInfo appInfo{};
    appInfo.sType              = VK_STRUCTURE_TYPE_APPLICATION_INFO;
    appInfo.apiVersion         = VK_API_VERSION_1_0;
    appInfo.pEngineName        = "No Engine";
    appInfo.engineVersion      = VK_MAKE_VERSION(1, 0, 0);
    appInfo.pApplicationName   = "Hello Triangle";
    appInfo.applicationVersion = VK_MAKE_VERSION(1, 0, 0);

    VkInstanceCreateInfo createInfo;
    createInfo.sType            = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
    createInfo.pApplicationInfo = &appInfo;

    uint32_t glfwExtensionCount        = 0;
    const char **glfwExtensions        = glfwGetRequiredInstanceExtensions(&glfwExtensionCount);
    createInfo.enabledExtensionCount   = glfwExtensionCount;
    createInfo.ppEnabledExtensionNames = glfwExtensions;
    createInfo.enabledLayerCount       = 0;

    if (vkCreateInstance(&createInfo, nullptr, &instance) != VK_SUCCESS) {
        throw std::runtime_error("failed to create Vulkan Instance!");
    }
}

int main()
{
    HTA app;

    try {
        app.run();
    } catch (const std::exception &e) {
        std::cerr << e.what() << "\n";
        return EXIT_FAILURE;
    }

    return EXIT_SUCCESS;
}

compile with:

g++ --std=c++17 -Wall -Wextra -O2 -lglfw -lvulkan -ldl -lpthread -lX11 -lXxf86vm -lXrandr -lXi -o 00base 00base.cpp

gcc version is 10.2

show me the segmentation fault when i run it

zsh: segmentation fault (core dumped) ./00base

what's the problem?

Krenodeno commented 3 years ago

Can you run it with debugger to see where it comes from ? it's always a good way to find a bug.

I can see a thing from the code standpoint: the GLFW_INCLUDE_VULKAN define have to be defined before including glfw, but you either include vulkan yourself or let glfw do it for you with the define, but don't do the two.

fake-rookie commented 3 years ago

I already add -g option to compiled and run with gdb. Set many breakpoint and run it. But no found. (also no coredump file generator)

I tried to change GLFW_INCLUDE_VULKAN as your suggested. The same result.

Krenodeno commented 3 years ago

Okay, can you modify the glfw initialization step like this :

void HTA::initWindow()
{
    if (!glfwInit()) {
        exit -1;
    }
    glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
    glfwWindowHint(GLFW_RESIZABLE, GLFW_FALSE);

    window = glfwCreateWindow(WIDTH, HEIGHT, "Vulkan Triangle", nullptr, nullptr);
    if (window == NULL) {
        exit -2;
    }
}

It should help telling if it comes from glfw.

Krenodeno commented 3 years ago

I just tested your exemple, and I did not get any error, so I suggest you verify if your installation is correct: GLFW is installed as a library and a development library, and same for vulkan (or via the sdk).

fake-rookie commented 3 years ago

I tested this code:

void HTA::initWindow()
{
    if (!glfwInit()) {
        exit -1;
    }
    glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
    glfwWindowHint(GLFW_RESIZABLE, GLFW_FALSE);

    window = glfwCreateWindow(WIDTH, HEIGHT, "Vulkan Triangle", nullptr, nullptr);
    if (window == NULL) {
        exit -2;
    }
}

Also the same result.

I think the GLFW is no problem with installation.

I wrote other GLFW program can work as normal.

Maybe the Vulkancan has problem.

But i run the vkcube is normal.

Following is what Vulkan package i installed.

extra/spirv-tools 2020.6-1 (vulkan-devel) [installed]
extra/vulkan-headers 1:1.2.171-1 (vulkan-devel) [installed]
extra/vulkan-icd-loader 1.2.171-1 [installed]
extra/vulkan-intel 20.3.4-3 [installed]
extra/vulkan-tools 1.2.171-1 (vulkan-devel) [installed]
extra/vulkan-validation-layers 1.2.166-1 (vulkan-devel) [installed]

I use Arch Linux and installed that with pacman.

Did not download the SDK directly.

Is that a problem?

Krenodeno commented 3 years ago

It's odd, I also developed some Vulkan programs on an Arch machine and never had this behavior.

Are the examples running ? like vulkaninfo or vkcube

mj-saunders commented 3 years ago

@fake-rookie do you have more than one GPU?

Since I updated kernel recently, I got segfaults that I don't remember having before. I've got an intel GPU and discrete nvidia in my laptop, running Arch.

Have a feeling this is different from your issue, as you can run vkcube without something like the following.

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/intel_icd.x86_64.json vkcube ^ the icd file may of course be different

The issue is an uninitialized pNext pointer in VkInstanceCreateInfo createInfo;

Change it to VkInstanceCreateInfo createInfo{}; and the crash will go away. ALWAYS initialize vulkan structs (even if to zero). Many of them have pointers in them that the driver nor validation layers have no clue if they are valid or not. If they aren't null, they assume its valid because there is no other way to check. So always initializing everything to zero (just by putting {} after the name) is good practice.

Yes. Has two GPUs on my laptop. Same of one Intel and one Nvidia.

And the F****** Nvidia driver also bothered me. One times make me reinstall the OS.

charles-lunarg commented 3 years ago

Replace this code

    VkInstanceCreateInfo createInfo;
    createInfo.sType            = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
    createInfo.pApplicationInfo = &appInfo;

with this.


    VkInstanceCreateInfo createInfo{}; //Note the {} after the name
    createInfo.sType            = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
    createInfo.pApplicationInfo = &appInfo;

The crash will go away. VkInstanceCreateInfo has a member called pNext of type const void*. When you don't provide a value for it (or don't use {} to reset it to zero), the value is uninitialized. This means the value is literally whatever was in the memory before hand. And because there is no way to tell if a pointer 'is valid', eg points to something inside the process address space, the driver will try to dereference it. When it does this, you get a crash because it isn't a valid pointer.

Thanks!

I'll try it.
