Windows executable crashes on other machines

[grave maple]

I am trying to build a windows executable that can run on other windows machines, but so far the executable works fine on my machine, while it hangs for 15-20 seconds on other machines and then just exits. My build.zig is the following:

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "spacer",
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });

    if (optimize != .Debug) {
        exe.subsystem = .Windows;
    }

    // Engine
    const engine = b.createModule(.{
        .root_source_file = .{ .path = "src/engine/engine.zig" },
    });

    exe.root_module.addImport("engine", engine);
    exe.addLibraryPath(.{ .cwd_relative = "external/sdl/lib/x64" });
    exe.linkSystemLibrary("SDL2");
    exe.addLibraryPath(.{ .cwd_relative = "external/sdl-ttf/lib/x64" });
    exe.linkSystemLibrary("SDL2_ttf");
    exe.addLibraryPath(.{ .cwd_relative = "external/sdl-image/lib/x64" });
    exe.linkSystemLibrary("SDL2_image");

    exe.addWin32ResourceFile(.{
        .file = .{ .cwd_relative = "src/spacer.rc" },
    });

    b.getInstallStep().dependOn(&b.addInstallArtifact(
        exe,
        .{ .dest_dir = .{ .override = .{ .custom = "../" } } },
    ).step);
}

And the entrypoint in main.zig is:

extern "kernel32" fn CreateMutexA(lpMutexAttributes: ?*const *opaque {}, bInitialOwner: w.BOOL, lpName: w.LPCSTR) callconv(w.WINAPI) w.HANDLE;
extern "user32" fn MessageBoxA(hwnd: ?w.HWND, lpText: w.LPCSTR, lpCaption: w.LPCSTR, uType: w.UINT) w.INT;

const MessageBox = struct {
    const button_ok: w.UINT = 0x0;
    const icon_error: w.UINT = 0x10;
};

pub export fn wWinMain(_: w.HINSTANCE, _: ?w.HINSTANCE, _: ?w.LPWSTR, _: w.INT) callconv(w.WINAPI) w.INT {

The problem isn't missing SDL dlls as those were present in the same directory as the executable on all other machines I tested on.

My machine is an intel CPU Windows 11 while most of the other machines I tested on were running Windows 10 (again Intel laptop CPUs).

might be api related, try running it just by double cliking it

running windows executables via command line don't show the "functions not found" dialog boxes

[grave maple]

Doesn't run from either CMD or double clicking the exe. In debug mode where CMD is present it just hangs on blank console and closes in 15-30 sec. On release version without CMD it just does nothing and closes (there was no message box error).

try to add -Dtarget=x86_64-windows-gnu to your zig build command (in your terminal)

sometimes, zig might use instructions that are specific to your cpu to optimize the binary

[grave maple]

Just for the record, it seems to produce the MessageBox even when ran from console. I'll try with the target now

[broken glacier]

try add sdl ttf too

[grave maple]

no that's when I removed it from my system

If I have it in the directory it just runs fine, I just wanted to test if CMD really does hid ethe messagebox

[broken glacier]

ok

what about now ?

[grave maple]

Worked. Thank you.
