Vala on Windows
Currently there are no official binary releases of Vala for Windows. However, a member of the Vala community provides builds for Windows. You can download an installer as .exe file which contains a minimalist GNU environment for Windows (MinGW) providing the GNU C compiler, the Vala compiler as well as the GLib and GTK+ libraries.
After successful installation you can compile your Vala programs:
> valac hello.vala
In order to suppress the additional console window for GTK+ applications you have to take the following steps:
Download MinGW API for MS-Windows
Extract w32api-x.xx-mingw32-dev.tar.gz into the Vala/MinGW installation directory
Pass -X -mwindows to the Vala compiler:
> valac -X -mwindows --pkg gtk+-2.0 hellogtk.vala
