Hey all,
I'm learning Vala at the moment, primarily with the intention to develop
apps
which support JACK audio output. I'm gonna work towards GStreamer based
audio routing, and JACK Transport to Start/Stop my app.
For the while, I hope to have a play around with JACK using Vala. So I went

Hey all,
I'm wondering how things work if I develop my program using ValaIde, and
then
I want to compile it on a different PC/Platform.
Would I have to download the ValaIde for that platform?
Or could I do some valac -vide main.vala kind of magic?
Cheers, -Harry

Hey all,
I'm attempting to learn how to write .vapi files manually. I've looked
trough
the Jack binding, the GTK+ binding and the sfml bindings.
Yet im stumped as to how to write a wrapper for the dead-simple function

Hey All,
I've got a function in the JACK.vapi binding, that returns a buffer. Now it
doesnt "physically"
return the buffer, but returns a void* to the buffer.
I checked the Vala tutorial for any references to void*, and didnt find
anything...
This is the function (to be called on a Port object

Hey,
I've no experience with Multi-Dimensional arrays in Vala, but I can quote a
tutorial:
http://live.gnome.org/Vala/ValaForJavaProgrammers#Arrays
It provides the basics of Vala for Java programmers (me.. in college ;-(
but also has a piece that might be of intrest to you.

I'm getting some strange errors... I'm trying to use a global int to count

but when I try compiling this:

return 0;
}
I get the following errors:

Hey,
Coming from a C++ background I first tried typeHere nameHere[]; too.
I noticed that newer languages seemed to have type[] name; configuration
(Java, C# etc).
I'm not part of the Vala team though, so I dont know the "official" status!

Hey Nicolas,
Any chance you'd compile with valac --save-temps ?
And then maybe post line 113 from your test.c file so we can see what's
really going on there?

Hey,
The link you posted seems dead, I got a "page not found" after clicking
it..?
OTOH: Have you tried rebuilding your pipeline using the "gst-launch" command
line tool?
This should show if its a GStreamer error, or your code...
I'm not familiar with GSt much, so I'll only be of limited use.

Hey Rafael,
What I've done when things don't seem to work, is figure out what the exact
command is to
compile the C file, and then edit the C file & compile it. (Without valac,
because as you said,
that would overwrite the C file.)
How you can do this is pass valac the --save-temps switch, and

I had this working before, but due to Hard disk issues I lost the .vapi.

Hey all,
Very simple question: Im looking for a "quit()" function, or "exit()".
Does it exist? I'm trying to use it to quit the whole program from a

Hey Nigel,
Indeed if not told to keep the temporary files, valac will by default remove
them after a compile.
if compiling from the command line (which I highly recommend [1]), do the
following:
valac --save-temps file.vala
