Linux

Download the SDK bundle for linux-amd64 and put main.c beside the folders it unzipped:

my_game/
├── include/
│   └── natiny.h
├── lib/
│   └── libnatiny_linux_amd64.a
└── main.c

#include "natiny.h"
#include <stddef.h>

static NatinyWindow window;

static void frame(float dt, void* userdata)
{
    (void)dt;
    (void)userdata;

    natiny_window_bind(window);
    natiny_render_clear(0.07f, 0.09f, 0.13f, 1.0f);
    natiny_render_set_color(0.66f, 0.76f, 0.22f, 1.0f);
    natiny_render_rectangle(360.0f, 260.0f, 80.0f, 80.0f);
    natiny_window_unbind();
}

int main(void)
{
    if (!natiny_backend_init(NATINY_BACKEND_AUTO)) {
        return 1;
    }

    window = natiny_window_create("Hello, Natiny", 800, 600);
    if (!window) {
        natiny_backend_shutdown();
        return 1;
    }

    natiny_backend_loop(frame, NULL);
    natiny_backend_shutdown();
    return 0;
}

Compile and link:

clang -O2 -Iinclude -c main.c -o main.o
clang -O2 main.o lib/libnatiny_linux_amd64.a -o app \
    -lGL -lX11 -ldl -lpthread -lm

./app

A dark window opens with a green square in it. gcc works just as well; nothing on that line is clang-specific.

libnatiny_linux_amd64.a is the whole engine - GLFW, the shader compiler, the mixer and the physics solver are already inside it, so there is nothing else of Natiny's to link. It is plain C with no C++ runtime anywhere, so a C compiler is all you need.

The five libraries on the link line are the system's. You need their development packages to build - on Debian and Ubuntu that is libgl1-mesa-dev and libx11-dev - but not to run.

One archive carries both backends this platform can run, Vulkan and OpenGL. NATINY_BACKEND_AUTO picks Vulkan; pass NATINY_BACKEND_OPENGL to choose the other. Vulkan is opened at run time rather than imported, so a machine with no Vulkan driver still starts and still runs OpenGL.

The SDK README in the bundle has the same commands for arm64 and i386, and for linking libnatiny_linux_amd64.so instead of the archive.
