SDL Development

Hello,
I’m beginning into programming and I tried to set up SDL2 on code::blocks but i always got this errors:

Erreur codeblocks SDL2
Erreur codeblocks SDL2821×184 11.5 KB

I followed several tutos and it always finishes like that…
Can you help me ?

on MS Windows 10

download codeblocks
https://www.codeblocks.org/downloads/binaries/
I have
codeblocks-20.03mingw-nosetup.zip

download SDL2
https://www.libsdl.org/download-2.0.php
I have
SDL2-devel-2.0.14-mingw.tar.gz (MinGW 32/64-bit)

make a folder
C:\Projects\dependencies\SDL2\

unzip
SDL2-devel-2.0.14-mingw.tar.gz
and put this folder
x86_64-w64-mingw32
in
C:\Projects\dependencies\SDL2
so you have
C:\Projects\dependencies\SDL2\x86_64-w64-mingw32

open codeblocks and create a new project / console application
project title = sdl_demo
Folder to create project in = C:\Projects\sdl\

hit ok and finish

in codeblocks menu select
Project / Build Options
make sure the project name is selected (not Debug or Release)

select
Search Directories \ Compiler
Add
C:\Projects\dependencies\SDL2\x86_64-w64-mingw32\include\SDL2
OK

select
Search Directories \ Linker
Add
C:\Projects\dependencies\SDL2\x86_64-w64-mingw32\lib
OK

select
Linker Settings \ Link Libraries
Add
mingw32
SDL2main
SDL2

go to
D:\Projects\dependencies\SDL2\x86_64-w64-mingw32\bin

copy
SDL2.dll

put it in
D:\Projects\sdl\sdl_demo

so you have
D:\Projects\sdl\sdl_demo\SDL2.dll

now go to google image search and type
sample.bmp

hopefully you’ll find a bitmap you like

I found some here
–BMP Files

I downloaded dots.bmp
and saved it to
C:\Projects\sdl\sdl_demo

now in your project in codeblocks open main.cpp and enter the following code
and from the codeblocks menu choose Build / Build and run

#include <SDL.h>

int main(int argc, char *argv[])
{
    SDL_Window *window;
    SDL_Renderer *renderer;
    SDL_Surface *surface;
    SDL_Texture *texture;
    SDL_Event event;

    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't initialize SDL: %s", SDL_GetError());
        return 3;
    }

    if (SDL_CreateWindowAndRenderer(320, 240, SDL_WINDOW_RESIZABLE, &window, &renderer)) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't create window and renderer: %s", SDL_GetError());
        return 3;
    }

    surface = SDL_LoadBMP("dots.bmp");
    if (!surface) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't create surface from image: %s", SDL_GetError());
        return 3;
    }
    texture = SDL_CreateTextureFromSurface(renderer, surface);
    if (!texture) {
        SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, "Couldn't create texture from surface: %s", SDL_GetError());
        return 3;
    }
    SDL_FreeSurface(surface);

    while (1) {
        SDL_PollEvent(&event);
        if (event.type == SDL_QUIT) {
            break;
        }
        SDL_SetRenderDrawColor(renderer, 0x00, 0x00, 0x00, 0x00);
        SDL_RenderClear(renderer);
        SDL_RenderCopy(renderer, texture, NULL, NULL);
        SDL_RenderPresent(renderer);
    }

    SDL_DestroyTexture(texture);
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);

    SDL_Quit();

    return 0;
}
