raylib :: Making the barest code required for a blank window

Question

Greetings

I'm very new to C. I would like to know the most minimal amount of steps/code for making a basic window using raylib. I'm using Linux and have followed the steps on github https://github.com/raysan5/raylib/wiki/Working-on-GNU-Linux, but I honestly don't know where to begin to build my own project. Is cmake or make required for a basic window like in the example: core_basic_window.c, that I'm able to compile (using the instructions from github, but I'm not sure how to modify/simply the code for my own project). Thank you : )

I've tried to copy and past this code from the github pull/project/directory and run gcc on it but I get error messages:

// Filename: core_basic_window.c

#include "raylib.h"

int main(void)
{
    // Initialization
    //--------------------------------------------------------------------------------------
    const int screenWidth = 800;
    const int screenHeight = 450;
 
    InitWindow(screenWidth, screenHeight, "raylib [core] example - basic window");
 
    SetTargetFPS(60);               // Set our game to run at 60 frames-per-second
    //--------------------------------------------------------------------------------------
 
    // Main game loop
    while (!WindowShouldClose())    // Detect window close button or ESC key
    {
        // Update
        //----------------------------------------------------------------------------------
        // TODO: Update your variables here
        //----------------------------------------------------------------------------------
 
        // Draw
        //----------------------------------------------------------------------------------
        BeginDrawing();
 
            ClearBackground(RAYWHITE);
 
            DrawText("Congrats! You created your first window!", 190, 200, 20, LIGHTGRAY);
 
        EndDrawing();
        //----------------------------------------------------------------------------------
    }
 
    // De-Initialization
    //--------------------------------------------------------------------------------------
    CloseWindow();        // Close window and OpenGL context
    //--------------------------------------------------------------------------------------
 
    return 0;
}

Couldn't compile:

You didn't like your libraries right. If you are using the Notepad++ option then: Create a Folder, and create a main.cpp/.c file. -> Navigate to the Raylib download folder, extracted of course, and click npp->then click notepad++.exe In notepad++ click file->Open (or Ctrl-O) then navigate to the folder you created for your project-> Write code then click F6 to run. That should be simple to follow instructions.

Compiler Flags (for GCC)

echo > Setup required Environment
echo -------------------------------------
SET RAYLIB_PATH=C:\raylib\raylib
SET COMPILER_PATH=C:\raylib\w64devkit\bin
ENV_SET PATH=$(COMPILER_PATH)
SET CC=gcc
SET CFLAGS=$(RAYLIB_PATH)\src\raylib.rc.data -s -static -Os -std=c99 -Wall -I$(RAYLIB_PATH)\src -Iexternal -DPLATFORM_DESKTOP
SET LDFLAGS=-lraylib -lopengl32 -lgdi32 -lwinmm
cd $(CURRENT_DIRECTORY)

cmd /c IF EXIST $(NAME_PART).exe del /F $(NAME_PART).exe

cmd /c IF EXIST $(NAME_PART).exe $(NAME_PART).exe

If you put this into a main.bat file or something it should give you a raylib runtime.
