yes

patent hill
#

also if you are using cmake please send the cmake script too

soft dawn
#

The main element is already defined in the losowegowno.obj element

soft dawn
#

at least one multiply defined symbol was found

patent hill
#

so did u use headerguards or did u include a header multiple times?

soft dawn
#

no i have only one void main

patent hill
#

can u sendcode for the main function?
Because the main function cannot be void?

soft dawn
#

#include "raylib.h"

int main(void)
{

const int screenWidth = 800;
const int screenHeight = 450;

InitWindow(screenWidth, screenHeight, "raylib [core] example - basic window");

SetTargetFPS(60);
while (!WindowShouldClose())
{

    BeginDrawing();

    ClearBackground(RAYWHITE);

    DrawText("Congrats! You created your first window!", 190, 200, 20, LIGHTGRAY);

    EndDrawing();
    
}
CloseWindow();
return 0;

}

#

this is the whole code

patent hill
#

so the code seems to be correct
can u send the compile output soemthing like this for example

x.cpp:1:1: error: ‘::main’ must return ‘int’
    1 | void main() {}
      | ^~~~

wait im new to vs where to find it?

patent hill
#

so how do u compile your project
if u click the button like the compile button u can find the output in the output page
or in the problems tab

so for your information the other cpp file named randomowegowno.cpp is also being compiled and both contradict on the main function
So you can like move it to another folder or you can remove it from compiling
randomwno is a TU which defines the main function. And also the main.cpp is a TU which defined the main function. these two contradict because there needs to be one unique deceleration of the main function. meaning you have to remove it from compilation and linking or you can remove the main function (comment it even) from the file to let the project compile
