Hello,
When I compile the following code :
public static int main(string[] args) {
int[] b = { 2, 4, 6, 8 };
foreach (int a in b)
stdout.printf("%d\n", a);
return 0;
}
with :
$ valac -C main.vala
$ gcc -Wunused-variable main.c -o main $(pkg-config --cflags --libs
glib-2.0)
I get the following warning :
main.c: In function ?_vala_main?:
main.c:38:8: attention : unused variable ?_a_collection_size_?
[-Wunused-variable]
gint _a_collection_size_ = 0;
^
What is the reason for this warning ?
Valac not clever enough to delete unused C variables.
Is it possible to get rid of it ?
Yes, ignore C warnings. Or fix vala, in this case it's not easy so I
don't suggest doing it :)
Thank you for your answer.
The problem is that when I compile vala code with the warning compilations flags
our build system enables, I have a lot of warnings. This one is only one amongst
others.
The risk is high to miss a real one in the mass...
Is it planned to "cleanup" this aspect of the generated C code ?
It would be interesting to dig into the code myself, but for now, I am not
sufficiently skilled in vala, so it would take too much time I think.
Concerning the other warnings I have, do you think it's worth it to submit them
to the mailing list ? Or will the answers be of the same kind ?
Thank you.
