When compiling from Debian the program works as intended, while compiling using
zig build -Dtarget=x86_64-windows-gnu on debian or just zig build on windows gives me lld linker errors.
On windows I followed the official gtk4 installation guide using msys2. However while compiling i noticed some linking issues were easily fixed by changing the file endings of some library files from .dll.a to .a.
Can someone help me find a way to compile to windows.
Build.zig
const std = @import("std");
pub fn build(b: *std.Build) void {
const target = b.standardTargetOptions(.{});
const optimize = b.standardOptimizeOption(.{});
const exe = b.addExecutable(.{
.name = "src",
.root_source_file = .{ .path = "src/main.zig" },
.target = target,
.optimize = optimize,
});
exe.linkSystemLibrary("c");
exe.linkSystemLibrary("gtk4");
b.installArtifact(exe);
const run_cmd = b.addRunArtifact(exe);
run_cmd.step.dependOn(b.getInstallStep());
if (b.args) |args| {
run_cmd.addArgs(args);
}
const run_step = b.step("run", "Run the app");
run_step.dependOn(&run_cmd.step);
}
error on debian 12 without any tweaks:
