c++ - Visual Studio代码SFML没有这样的文件或目录

Question

您好，我一直在尝试使用 Visual Studo 代码来学习 C++ SFML。在观看了如何在 C++ 中安装 sfml 的教程后，我已经准备好了一切。但是，问题是当我尝试编译时它给了我这个错误:“main.cpp:2:10: fatal error :SFML/Graphics.hpp:没有这样的文件或目录”。我已经阅读了很多指南，但似乎没有一个起作用。

这是我的代码:

#include <SFML/Graphics.hpp>
#include <iostream>
int main() {
    sf::RenderWindow window(sf::VideoMode(1280,720),"Nareszcie");
    while(window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type==sf::Event::Closed)
            {
                window.close();

            }
            window.clear();
        }
    }
    return 0;
}

希望有人能帮我解决这个问题。

您还需要将包含目录添加到构建说明中。

"args": [
    "-g",
    "${file}",
    "-o",
    "${fileDirname}\\${fileBasenameNoExtension}.exe",
    "-I",
    "C:/SFML-2.5.1/include/"
],

但是，您还需要将可执行文件链接到 SFML 库。

"args": [
    "-g",
    "${file}",
    "C:/path/to/sfml/libsfml-graphic.a" // something like that
    "-o",
    "${fileDirname}\\${fileBasenameNoExtension}.exe",
    "-I",
    "C:/SFML-2.5.1/include/",
],

我的建议是使用适当的构建系统，例如 CMake、meson 或其他系统，它们会自动执行此类操作。这是一个 CMake 示例:

cmake_minimum_required(VERSION 3.14)
project(your-project CXX)

# creates your executable with two cpp file in it
add_executable(my-exe main.cpp otherfile.cpp)

# find sfml. Assume the command line argument -DCMAKE_PREFIX_PATH="C:/SFML-2.5.1"
find_package(SFML 2.5.1 COMPONENTS graphic REQUIRED)

# configure your project correctly. Take care of include directories and linking
target_link_libraries(my-exe PUBLIC sfml-graphic)

VSCode 还为这些构建系统提供了一个很好的插件。
