vscode中的sdl.h没有这样的文件或目录

Question

I'm trying to add the relevant "-I"path_to_your_SDL_include_directory"" as outlined in several similar posts such as

我的文件结构如下。我的main.cpp在myproject/src中。我已经复制了SDL的所有内容。 sdl2.dll生活在myproject/lib/sdl2_lib中。

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;
}

编辑：我还应该添加一个添加一个随机文件名而不是sdl.h强调整个Include语句，而不仅仅是结束。很明显，VSCODE确实知道它存在，它只是不会将其添加到程序中，这就是我猜测

Edit2：运行Make从PowerShell发出以下错误：

Answer 1

显然，您有两个问题。

1. VSCODE的C ++扩展程序抱怨文件SDL2.h
2. 当您从makefile中编译时，有一个链接问题

，让我们首先解决makefile的内容：

您的makefile中有一个错字，它说sdl2_lib/code而不是<< 代码> sdl2_lib/lib 。

修复此操作后，您必须添加库以链接。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

代码

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

> 请提供编译器输出（作为文本，而不是图像），但请勿在尝试此操作之前：

选项：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（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：

我不认为有您的配置有任何错误。

Answer 2

我没有使用Windows和Vscode，但我想您可以尝试

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

Answer 3

标志之间不应该有空间
IE
“ -i lib/sdl2_lib/include”应该是“ -ilib/sdl2_lib/include”
“ -l lib/sdl2_lib/lib”应为“ -llib/sdl2_lib/lib”

MACOS

安装工具和LIB

brew install gcc
brew install sdl2
brew install sdl2_image

创建项目结构

mkdir -p game_app/{include,lib,src,build/debug}

cd game_app
cat << src/main.c << _EOF
#include <stdio.h>
#include <stdlib.h>
#include <SDL2/SDL.h>

typedef struct App
{
  SDL_Window *window;
  SDL_Renderer *renderer;
} App;

int main(void)
{
  printf("Hello, world!\n");
  return EXIT_SUCCESS;
}

_EOF

code .
