[Vala] compiler warning for Variant.strv()

[Yasushi SHOJI <yasushi shoji gmail com>]

Hi,

I have a code snippet which gets incompatible pointer type warning
from gcc.

Is there anyway to fix this except "-Wno-incompatible-pointer-types"?


$ cat a.vala
using Gee;

void main () {
        Variant ary = new Variant.strv({"foo", "bar", "baz"});
}


$ valac --pkg gee-0.8 a.vala --no-color
a.vala:4.11-4.55: warning: local variable `ary' declared but never used
        Variant ary = new Variant.strv({"foo", "bar", "baz"});
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
