[Vala] Problems with building app with GStreamer in MSYS2/Win64

["marcin saepia net" <marcin saepia net>]

Hello

I am trying to build simple app written in Vala 0.30 and link them with
windows 64-bit build of GStreamer 1.6.1. I also want to reuse GObject, GLib
and Soup that ship with GStreamer so I don't introduce another dependencies.

I apologize if this is not truly Vala related, but I cannot assess whether
this is related to boilerplate code generated by Vala or not.

I've fetched MSYS2 and added lib/pkgconfig from GStreamer installation dir
to the PKG_CONFIG_PATH and pkg-config correctly recognizes all libraries.

However, when I try to build the app the following error occur.

I've found out that such issue often is related to cross-compilation issues
but I have no clue how to proceed with this exact case. Any suggestions?

Log below,

thank you

Marcin
