Hi,
I've wanted to restart working on my vala branch of cheese. In the
meantime vala has received quite some changes. Therefore it does not
compile anymore. The main problem I have are "ref" variables. For
example with the text_extents method of Cairo
TextExtents extents;
text_extents ("hello", ref extents);
This does not compile because the compiler says.
"use of possibly unassigned local variable `extents' text_extents
("hello", ref extents);"
What should I do here or is it a bug in text_extents?
or also this code
RawError dbus_error;
dbus_error.init ();
var hal = new Hal.Context ();
if (hal == null)
throw new WebcamError.FAILED ("Error getting HAL
context");
if (!hal.set_dbus_connection (RawBus.get (BusType.SYSTEM, ref
dbus_error)))
throw new WebcamError.FAILED ("Error setting dbus
connection:
%s".printf (dbus_error.message));
complains about the fact that dbus_error is unassigned.
Any help will be highly appreciated
Thanks
Jaap
