我通常只编写高级代码，所以我完全没有编译代码的经验（因为 IDE 通常为我这样做）所以我可能会忽略一些非常明显的东西。我花了很多时间弄清楚如何在 Linux 中编译 Vala，但我似乎无法完成这项工作。
这些是我采取的步骤：
- 我安装了 valac、gtk、mingw64（我构建了一个 docker 映像只是为了确保：0620731/valac:mingw64）
- 从展示 gtk3 的 gnome 教程中复制了一些工作 vala 代码。
- 运行这个： valac --cc=x86_64-w64-mingw32-gcc-win32 --pkg gtk+-3.0 -X -mwindows ../main.vala （我也尝试了不同的编译器。结果各不相同，但没什么好处。）
我得到的输出是：

我也尝试编译 c 文件，但我得到了完全相同的结果，所以它不是一个错误的版本。
虽然我设法在 Windows 上编译了同一个项目，所以并不是所有的都丢失了，但我真的希望能够在没有双启动/VM 的情况下做到这一点。我很亲密，我现在不想放弃。
这可能很有用（main.vala）：
using Gtk;
int main(string[] args) {
Gtk.init(ref args);
var window = new Window();
window.title = "First GTK+ Program";
window.border_width = 10;
window.window_position = WindowPosition.CENTER;
window.set_default_size(350, 70);
window.destroy.connect(Gtk.main_quit);
var button = new Button.with_label("Click me!");
button.clicked.connect(() => {
button.label = "Thank you";
});
window.add(button);
window.show_all();
Gtk.main();
return 0;
}
