Error code 53 on Windows

[Billuc]

Hi,
I am new to Zig and wanted to try this library.
However I am having a problem when running my program with the following error

run
└─ run administrative failure
error: the following command exited with error code 53:
C:\Users\luc.billaud\Code\Perso\myproject\zig-out\bin\myproject.exe

I tried both static linking and automatic fetch and build.

Here is my code :

pub fn main() !void {
    var alloc = std.heap.GeneralPurposeAllocator(.{}){};
    const allocator = alloc.allocator();
    var open_err: ?[]u8 = null;
    _ = zuckdb.DB.initWithErr(allocator, "db.duckdb", .{}, &open_err) catch |err| {
        defer allocator.free(open_err.?);
        std.debug.print("DB open: {any} {any}", .{ open_err.?, err });
    };
}

Could the problem be linked to the fact that I am on Windows ?

Additional information :

• Zig v0.14.0
• Latest DuckDB version (1.2.1 on Windows)
• Windows 11
• ZuckDB installed via zig fetch --save git+https://github.com/karlseguin/zuckdb.zig

Thanks in advance !

I honestly don't know. AFAIK, you're the first person to try on windows. Not even clear how far it's getting, whether the issue is in the library, duckdb or Zig.

IF you really want to dig into this, it might be interesting to see if you're able to get a C / C++ project working. If you're able to get it working in C/C++, then maybe we can figure out what's different. If not, the duckdb discord group might be able to help.

I have no way to test / debug this.

Hi, okay i'll try this whenever I have dome time ;) Thx

I got it working in Windows. The issue is that it doesn't find the DLL file.

@Billuc Try adding in your build.zig:

if (builtin.target.os.tag == .windows) {
    b.installFile("lib/duckdb.dll", "bin/duckdb.dll");
}

I don't know if this is the canonical way of doing this, but it works.

Also, thanks @karlseguin for the effort of implementing this :)
