Re: [Vala] glib-2.0 - glib-2.0.vapi mismatch bug: TestFixtureFunc vs TestFunc

[Felipe Lavratti <felipelav gmail com>]

Daniel, tried with --target-glib=2.44 and the warning stills.

The valac line that generate the error is this:
/usr/bin/valac -C -b /home/fanl/workspace-beyond/software/vatom -d
/home/fanl/workspace-beyond/software/vatom/build --pkg=gio-2.0
--pkg=gee-0.8 --pkg=posix --target-glib=2.44 --thread --debug
/home/fanl/workspace-beyond/software/vatom/src/main.vala
/home/fanl/workspace-beyond/software/vatom/build/atom.vapi

The thing is, glib 2.44 _does uses_ the GTestFixtureFunc type, but the
vala.api does not, have a look here:
http://ftp.gnome.org/pub/gnome/sources/glib/2.44/glib-2.44.0.tar.xz >>
/glib-2.44.0/glib/gtestsutil.h

I think that in the glib-2.0.vapi file the test macro `#if GLIB_2_26` is
failing because the symbol `GLIB_2_26` is not defined, instead I found this
symbol in the glib headers:
/usr/include/glib-2.0$ ag -i 2_26
glib/gversionmacros.h
39: * GLIB_VERSION_2_26:
46:#define GLIB_VERSION_2_26 (G_ENCODE_VERSION (2, 26))
