Skia OpenGL 函数执行完成时崩溃记录

运行环境:

　　系统: Win10 

　　Skia版本: Skia m110（通过JetBrains下的skia-pack项目下载的编译好的包）

　　窗口框架:glfw3

问题代码

#include <iostream>
#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <GL/gl.h>
#define SK_GL
#include "include/gpu/GrDirectContext.h"
#include "include/gpu/gl/GrGLInterface.h"
#include "include/core/SkSurface.h"
#include "include/core/SkColorSpace.h"
#include "include/core/SkCanvas.h"
#include <conio.h>
#include <thread>


int main() {
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    auto window = glfwCreateWindow(800, 600, "Skia + OpenGL", nullptr, nullptr);
    glfwMakeContextCurrent(window);

    sk_sp<const GrGLInterface> interface = GrGLMakeNativeInterface();
    if(!interface) {
        printf("GrGLMakeNativeInterface fail.");
        return 1;
    }

    sk_sp<GrDirectContext> grContext = GrDirectContext::MakeGL(interface);
    if(!grContext) {
        printf("MakeGL fail.");
        return 1;
    }
    int width, height;
    glfwGetFramebufferSize(window, &width, &height);
    cout << "buff w:" << width << ", h:" << height << endl;



    GrGLFramebufferInfo fbInfo;
    fbInfo.fFBOID = 0;  // 默认帧缓冲
    fbInfo.fFormat = GL_RGBA8;

    GrBackendRenderTarget backendRenderTarget(width, height, 0, 0, fbInfo);//注释后不崩溃





}

 

　发现运行以上代码会崩溃，当注释这句后，main函数执行完不会崩溃:

GrBackendRenderTarget backendRenderTarget(width, height, 0, 0, fbInfo);

　通过VS调试，发现崩溃报错:

Run-Time Check Failure #2 - Stack around the variable 'backendRenderTarget' was corrupted.

　栈损坏报错...不确定是不是m110这个版本对Windows兼容不好的原因.

问题解决

同样大致一样的代码，尝试换m93、m116不会崩溃。

 

 

发现网上对PC端Skia的GPU相关的示例是真的少，最后附上Skia PC端简单示例(OpenGL):

    int winSize = 800;
    glfwInit();
    glfwWindowHint(GLFW_RED_BITS, 8);
    glfwWindowHint(GLFW_GREEN_BITS, 8);
    glfwWindowHint(GLFW_BLUE_BITS, 8);
    glfwWindowHint(GLFW_ALPHA_BITS, 8);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_STENCIL_BITS, 8);
    auto window = glfwCreateWindow(winSize, winSize, "Skia + OpenGL", nullptr, nullptr);
    glfwMakeContextCurrent(window);

    sk_sp<const GrGLInterface> interface = GrGLMakeNativeInterface();
    if(!interface) {
        printf("GrGLMakeNativeInterface fail.");
        return 1;
    }
    sk_sp<GrDirectContext> grContext = GrDirectContext::MakeGL(interface);
    if(!grContext) {
        printf("MakeGL fail.");
        return 1;
    }

    GrGLFramebufferInfo framebufferInfo;
    framebufferInfo.fFBOID = 0;  // 默认的 FBO
    framebufferInfo.fFormat = GL_RGBA8;



    GrBackendRenderTarget backendRenderTarget(winSize, winSize, 0, 8, framebufferInfo);

    sk_sp<SkSurface> surface = SkSurface::MakeFromBackendRenderTarget(
            grContext.get(),
            backendRenderTarget,
            kBottomLeft_GrSurfaceOrigin,
            kRGBA_8888_SkColorType,
            nullptr,
            nullptr
    );
    if (!surface) {
        printf("Failed to create Skia GPU surface.\n");
        return -1;
    }
    SkCanvas* canvas = surface->getCanvas();


    while (!glfwWindowShouldClose(window)) {
        glfwPollEvents();

        // 清屏（Skia 层面）
        canvas->clear(SK_ColorWHITE);

        SkPaint paint;
        paint.setColor(SK_ColorRED);
        paint.setAntiAlias(true);

        canvas->drawRect(SkRect::MakeXYWH(100, 100, 300, 200), paint);

        // 提交 GPU 绘图
        surface->flushAndSubmit();

        // 交换缓冲
        glfwSwapBuffers(window);
    }
    surface->flushAndSubmit();
    surface.reset();

    grContext->flush();
    grContext->abandonContext();
    grContext.reset();

    glfwMakeContextCurrent(nullptr);
    glfwDestroyWindow(window);
    glfwTerminate();

感谢GPT的辅助，让我能把Skia小的Hello World写出来。
