Thanks for report. I'm surprised as Fedora 23 is one of my test beds. Let me fire up the VM.

Checking the vala dependencies.

$ sudo dnf install vala vala-devel vala-tools vala-doc

That looks OK. It's building fom the expected source (thanks Ubuntu).

I'm confused!

Yes. This is very strange it's internal to vala's dependency handling. Does

valac --pkg libsoup-2.4 --pkg posix --pkg gio-2.0 --pkg glib-2.0  -o qproxy genproxy.vala

change anything. It should not, as /usr/share/vala-0.30/vapi/libsoup-2.4.deps should define the gio dependency, and glib is a given.

[ohhorob]

No errors!

[rob@localhost qproxy]$ valac --pkg libsoup-2.4 --pkg posix --pkg gio-2.0 --pkg glib-2.0  -o qproxy genproxy.vala
/home/rob/mwptools/qproxy/genproxy.vala.c: In function ‘gen_proxy_default_handler’:

            ^
[rob@localhost qproxy]$

[stronnag]

And you have the file /usr/share/vala-0.30/vapi/libsoup-2.4.deps, which just contains 'gio-2.0' ?

[ohhorob]

[rob@localhost qproxy]$ ls -alh /usr/share/vala-0.30/vapi/libsoup-2.4.deps
-rw-r--r--. 1 root root 8 Sep 18  2015 /usr/share/vala-0.30/vapi/libsoup-2.4.deps
[rob@localhost qproxy]$ cat /usr/share/vala-0.30/vapi/libsoup-2.4.deps
gio-2.0
[rob@localhost qproxy]$

[stronnag]

And how about?

valac --pkg libsoup-2.4 --pkg posix --pkg gio-2.0 -o qproxy genproxy.val

and

$ valac -v  -X -O2 -X -s --thread --target-glib=2.46 --pkg libsoup-2.4 --pkg posix -o qproxy genproxy.vala

which should give:

(and an omission from the Makefile).

[stronnag]

pushed a new Makefile with --pkg gio-2.0 as it's harmless

git pull
make clean
make

No errors!
