[gentoo-user] Anyone here speak vala?

[walt]

I'm trying to install dev-libs/granite but the install fails with this bit of wit:

/var/tmp/portage/dev-libs/granite-0.2.3.1/work/granite-0.2.3.1/lib/Widgets/DynamicNotebook.vala:509.19-509.49: error: Return value transfers ownership but method return type hasn't been declared to transfer ownership
            get { return add_button.tooltip_text; }
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Sometimes I despair of software devs ever learning to communicate with humans :(

I don't know Vala but I can tell you what's going on. It's a version mismatch 
between the compiler and library. Since vala is in early stages the syntax is 
still changing. So the answer is to file a bug with gentoo.

However you can get it to compile with valac-0.24 but it looks for valac-0.26 
so:

# mv /usr/bin/valac-0.26 /usr/bin/valac-0.26.old
# cp /usr/bin/valac-0.24 /usr/bin/valac-0.26
# emerge dev-libs/granite

And then restore the original valac-0.26. This will compile successfully but 
with several warnings so it may not actually work.

Your workaround got granite installed, thanks.  My objective is to try to build
a promising calendar app I downloaded from the ElementaryOS project (all their
apps are written in vala).  So now I'll go try to make the calendar work :)

Thanks again.
