Compile Hello World

Compiling with mingw64

gcc -o hello -Wall hello.c `sdl2-config --cflags --libs`

Each time I install something for programming projects I get slightly closer to understanding what on earth is going on. Thank you for this page.

I am getting the following error :
C:/M/B/src/mingw-w64/mingw-w64-crt/crt/ucrtexewin.c:67: undefined reference to `wWinMain'

My vscode's tasks.json is :
{ "tasks": [ { "type": "cppbuild", "label": "C/C++: g++.exe build active file", "command": "C:\\msys64\\mingw64\\bin\\g++.exe", "args": [ "-fdiagnostics-color=always", "-g", "${file}", "-o", "${fileDirname}\\${fileBasenameNoExtension}.exe", "-I C:\\msys64\\mingw64\\include\\SDL2", "-L C:\\msys64\\mingw64\\lib", "-lSDL2main", "-lSDL2", "-mwindows", "-municode" ], "options": { "cwd": "${fileDirname}" }, "problemMatcher": [ "$gcc" ], "group": { "kind": "build", "isDefault": true }, "detail": "Task generated by Debugger." } ], "version": "2.0.0" }

My issue is fixed I had to replace int main with "int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow ){"

               And had to change the order of arguments:

Here's my final tasks.json:

{ "tasks": [ { "type": "cppbuild", "label": "C/C++: g++.exe build active file", "command": "C:\\msys64\\mingw64\\bin\\g++.exe", "args": [ "-fdiagnostics-color=always", "-g", "${file}", "-o", "${fileDirname}\\${fileBasenameNoExtension}.exe", "-I C:\\msys64\\mingw64\\include\\SDL2", "-L C:\\msys64\\mingw64\\lib", "-lmingw32", "-lSDL2main", "-lSDL2", "-lSDL2_image", "-mwindows" ], "options": { "cwd": "${fileDirname}" }, "problemMatcher": [ "$gcc" ], "group": { "kind": "build", "isDefault": true }, "detail": "Task generated by Debugger." } ], "version": "2.0.0" }

and this is my final code:

`#include <stdio.h>
#include <windows.h>
#include <SDL2/SDL.h>

const int WIDTH = 800, HEIGHT = 600;

solved my problem, thank you

big thanks friend

I want to compile ffmpeg-n4.4.1 with msys2 mingw64, it's request sdl version within "sdl2 >= 2.0.1 sdl2 < 2.1.0",
but the cmd pacman -Ss sdl2, show that this sdl2 version is mingw64/mingw-w64-x86_64-SDL2 2.32.2-1 [installed]
I cant find the correct version of SDL2, can you help me how to do? thank you very much.
