The logging system, when using main callbacks, doesn't display in the console on windows10.

[TheDWPCer]

The following print systems fail to display to the console:

std.debug.print("std.debug.print", .{});
sdlLog(null, .application, .critical, "sdlLog-application");
sdlErr("sdlErr");
try sdl3.log.log("sdl3-zig-log", .{});
sdl3.c.SDL_Log("SDL_Log");

sdlLog and sdlErr are copied from "template/src/main.zig"

when running the template example on windows, everything works (the image is drawn) but nothing it printed to the console.
the code above was ran in the init function.

pub fn init(
    app_state: *?*AppState,
    args: [][*:0]u8,
) !sdl3.AppResult {
    _ = args;

    // Setup logging.
    sdl3.errors.error_callback = &sdlErr;
    sdl3.log.setAllPriorities(.info);
    sdl3.log.setLogOutputFunction(void, &sdlLog, null);

    // Logging test begin
    std.debug.print("std.debug.print", .{});
    sdlLog(null, .application, .critical, "sdlLog-application");
    sdlErr("sdlErr");
    try sdl3.log.log("sdl3-zig-log", .{});
    sdl3.c.SDL_Log("SDL_Log");
    // Logging test end

    try log_app.logInfo("Starting application...", .{});

    // Prepare app state.
    const state = try allocator.create(AppState);
    errdefer allocator.destroy(state);

    // Setup initial data.
    const window_renderer = try sdl3.render.Renderer.initWithWindow(
        "Hello SDL3",
        WINDOW_WIDTH,
        WINDOW_HEIGHT,
        .{},
    );
    errdefer window_renderer.renderer.deinit();
    errdefer window_renderer.window.deinit();
    const tree_tex = try sdl3.image.loadTextureIo(
        window_renderer.renderer,
        try sdl3.io_stream.Stream.initFromConstMem(my_image),
        true,
    );
    errdefer tree_tex.deinit();

    // Prove error handling works.
    const dummy: ?sdl3.video.Window = sdl3.video.Window.fromID(99999) catch null;
    _ = dummy;

    // Set app state.
    state.* = .{
        .window = window_renderer.window,
        .renderer = window_renderer.renderer,
        .tree_tex = tree_tex,
    };
    app_state.* = state;

    try log_app.logInfo("Finished initializing", .{});
    return .run;
}

also, "Finished initializing" and "Starting application..." fail to show too.

The following consoles I try with:
Visual Studio Code's bash (MINGW),
git bash (MINGW),
terminal's cmd,
terminal's powershell

This is only for main callbacks, logging work perfectly without them on windows10.

This is weird, happens for me too.

Same for me on Win11.
Redirecting stderr to a file works though, e.g. template 2> err.txt
Also noticed that the template example won't spawn a console window (if started from Windows) whereas something like castholm's breakout example will spawn a console window.

[wilba]

If you remove sdl3.log.setLogOutputFunction(void, &sdlLog, null); or move it to after initWithWindow() then SDL3 log messages will output to stderr, as well as std.debug.print(), std.log.info() etc.

stderr just doesn't exist in init() before the window is created, so std.debug.print() etc. still don't work before the window is created... yet log_app.logInfo() does work.

Actually, moving sdl3.log.setLogOutputFunction(void, &sdlLog, null); before window creation isn't important... as I can leave it where it is... what makes the problem go away is calling a log function before calling sdl3.log.setLogOutputFunction... as if SDL is setting up something on the first log function. e.g. this works for me:

    // Setup logging.
    sdl3.errors.error_callback = &sdlErr;
    sdl3.log.setAllPriorities(.info);
    try sdl3.log.log("test", .{}); // *** added this
    sdl3.log.setLogOutputFunction(void, &sdlLog, null);

    try log_app.logInfo("Starting application...", .{});

[TheDWPCer]

// Setup logging.
sdl3.errors.error_callback = &sdlErr;
sdl3.log.setAllPriorities(.info);
try log_app.logInfo("Starting application...", .{});
sdl3.log.setLogOutputFunction(void, &sdlLog, null);

(slight modification above) [thanks @controlbionics-jason and @wilba]

This solution works on windows 10 with visual studio code, but only when using the cmd console and powershell console log (not the git bash console log)

This is a good enough fix for me right now. Thanks for your help.
This might be a git bash issue from this point on, but I think I'll leave this open for now until adding the intermediary logging statement is not required.
(Unless otherwise informed that this is correct)
Current Version of Git Bash is: git version 2.50.0.windows.1
