库已正确添加到智能感知中，但构建和调试失败

问题描述 投票：0回答：1

这是我在调试或运行时收到的错误。

这是Main.cpp：

// std
#include <stdio.h>

// opengl
#include <GL/glew.h>

#include <SDL2/SDL.h>


#define SCREEN_WIDTH 800
#define SCREEN_HEIGHT 600

int main(int argc, char* argv[])
{
    // Initialize SDL
    if(SDL_Init(SDL_INIT_VIDEO) < 0)
    {
        fprintf(stderr, "SDL couldn't initialize\n");
        return 1;
    }

    // @todo: implement createWindow method
    // Create window
    SDL_Window* window = SDL_CreateWindow(
        "Title", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
        SCREEN_WIDTH, SCREEN_HEIGHT,
        SDL_WINDOW_OPENGL | SDL_WINDOW_SHOWN

    if(!window)
    {
        fprintf(stderr, "Error creating window\n");
        return 2;
    }

    // SDL OpenGL settings

    );
    SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
    SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 24);
    SDL_GL_SetAttribute(SDL_GL_STENCIL_SIZE, 8);

    // SDL OpenGL context
    SDL_GLContext glContext = SDL_GL_CreateContext(window);

    SDL_GL_SetSwapInterval(1);

    // GLEW
    glewInit();
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_TEXTURE_2D);
    glEnable(GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

    // Game loop
    bool quit = false;

    while(quit == false)
    {
        SDL_Event windowEvent;

        while(SDL_PollEvent(&windowEvent))
        {
            if(windowEvent.type == SDL_QUIT)
            {
                quit = true;
                break;
            }
        }

        // @todo: implement render method
        // Render

        SDL_GL_SwapWindow(window);
    }

    // @todo: encapsulate method
    // Clean up
    SDL_GL_DeleteContext(glContext);

    return 0;
}

这是我的c_cpp_properties.json：

    "configurations": [
        {
            "name": "Linux",
            "includePath": [

                }
            ]
        }
    ]

这是我的tasks.json：

    "tasks": [

            "type": "cppbuild",

            "command": "/usr/bin/g++",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "-lSDL2",
                "-lGL"
            ],
            "options": {

            },

                "isDefault": true
            },
            "detail": "compiler: /usr/bin/g++"
        }
    ]
}

我尝试根据某些建议将 

"additionalSOLibSearchPath": "/usr/local/lib",
添加到 launch.json，我还尝试了计算机上的其他库位置，包括 SDL2 的直接路径。

我将 

"/usr/include/GL", "/usr/include/SDL2"
添加到 c_cpp_properties.json 文件的包含路径中 虽然这似乎只会改变智能感知。

我将 

"-lSDL2", "-lGL"
添加到了tasks.json。

如果这有帮助，这是我的 MakeFile：

我还在 MakeFile 中添加了 

CXXFLAGS = -std=c++11 -Wall -g
和 
LDFLAGS = -lSDL2 -lGL -lGLEW
。

此停止不应该发生，因为默认情况下它是禁用的。查找 .gdbinit 文件并从其中删除 

set stop-on-solib-events 1
或将其更改为 
set stop-on-solib-events 0
。

更新launch.json：

        "setupCommands": [
            {
                "description": "Enable pretty-printing for gdb",
                "text": "-enable-pretty-printing",
                "ignoreFailures": true
            },
            {
                "description": "Set Disassembly Flavor to Intel",
                "text": "-gdb-set disassembly-flavor intel",
                "ignoreFailures": true
            },
            {
                "description": "Don't stop the target when a shared library is loaded or unloaded",
                "text": "-gdb-set stop-on-solib-events 0",
                "ignoreFailures": true
            }
        ]
