SDL.h VSCode 中没有这样的文件或目录

问题描述 投票：0回答：4

我正在尝试添加相关的 

"-I"path_to_your_SDL_include_directory""
，如几篇类似帖子（例如 this one）中所述。我尝试了三种方法；将其添加到tasks.json、Makefile和c_cpp_properties.json中。

我的文件结构如下。我的 main.cpp 位于 

MyProject/src
中。我已将SDL的include文件夹的所有内容复制到
MyProject/lib/SDL2_lib/include
并将lib文件夹复制到
MyProject/lib/SDL2_lib/lib
。 
SDL2.dll
住在
MyProject/lib/SDL2_lib
。

以下是视觉摘要以及我的代码。

main.cpp

#include <iostream>
#include <SDL.h>


const int WIDTH = 800, HEIGHT = 600;

int main( int argc, char *argv[] )
{
    SDL_Init( SDL_INIT_EVERYTHING );

    SDL_Window *window = SDL_CreateWindow( "Hello SDL WORLD", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_ALLOW_HIGHDPI );

    if ( NULL == window )
    {
        std::cout << "Could not create window: " << SDL_GetError( ) << std::endl;
        return 1;
    }

    SDL_Event windowEvent;

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

    SDL_DestroyWindow( window );
    SDL_Quit( );

    return EXIT_SUCCESS;
}

    ],

}

尽管如此，我还是收到了错误；

如有任何帮助，我们将不胜感激！

编辑：我还应该补充一点，添加随机文件名而不是 

SDL.h
强调了整个包含语句而不仅仅是结尾。很明显，VSCode 确实知道它存在，只是没有将其添加到程序中，这就是我的猜测

Edit2：从 powershell 运行 

make
会出现以下错误；

c++ sdl-2

很明显你有两个问题。

  1. VSCode 的 C++ 扩展抱怨文件 SDL2.h
  2. 从 Makefile 编译时存在链接问题

让我们先解决 Makefile 的问题：

你的 Makefile 中有一个拼写错误，它写的是 

SDL2_lib/libr
而不是 
SDL2_lib/lib
。

修复此问题后，您必须添加要链接的库。从技术上讲，您只需要 

libSDL2.la
（假设动态链接），因为您已经编写了自己的 
main()
函数（因此您不需要 
SDL2main
。

因此，Makefile 中的命令行应该如下所示（请注意我如何将项目的文件放在库之前以保证正确加载符号，这在使用中间文件时变得更加重要）：

g++ -Ilib/SDL2_lib/include -Llib/SDL2_lib/lib src/main.cpp \
    -lmingw32 -lSDL2main -lSDL2 -mwindows \
    -o Main

如果这不起作用，请提供编译器输出（作为文本，而不是图像），但在尝试此操作之前不要提供：

选项一：指定整个库的文件名：

g++ -Ilib/SDL2_lib/include -Llib/SDL2_lib/lib src/main.cpp \
    -lmingw32 -lSDL2main.la -llibSDL2.la -mwindows \
    -o Main

选项二：静态链接（您不需要 DLL）

g++ -Ilib/SDL2_lib/include -Llib/SDL2_lib/lib src/main.cpp \
    -lmingw32 lib/SDL2_lib/lib/libSDL2main.a lib/SDL2_lib/lib/libSDL2.a -mwindows \
    -o Main

关于 VSCode：

我不认为你的配置有什么问题。您可能想尝试切换到反斜杠（无论如何，这不会产生任何影响）或（是的，确实如此）重新加载 VSCode。

我没有使用过 Windows 和 VSCode，但我想你可以尝试一下

g++ -I lib/SDL2_lib/include -Llib/SDL2_lib/lib -lsdl -o Main src/main.cpp

或

g++ -I lib/SDL2_lib/include -Llib/SDL2_lib/lib -lsdl2 -o Main src/main.cpp

标志之间不应有空格 IE “-I lib/SDL2_lib/include”应为“-Ilib/SDL2_lib/include” “-L lib/SDL2_lib/lib”应该是“-Llib/SDL2_lib/lib”
